Description
The HFBR/HFCT-53D3 transceiver from Agilent allows the system designer to implement a range of solutions for multimode and single mode Fibre Channel applications. The overall Agilent transceiver product consists of three sections: the transmitter and receiver optical subassemblies, an electrical subassembly, and the package housing which incorporates a duplex SC connector receptacle.
Transmitter Section The transmitter section of the HFBR-53D3 consists of an 850 nm Vertical Cavity Surface Emitting Laser (VCSEL) in an optical subassembly (OSA), which mates to the fiber cable. The HFCT-53D3 incorporates a 1300 nm FabryPerot (FP) Laser designed to meet the Fibre Channel specification. The OSA is driven by a custom, silicon bipolar IC which converts differential PECL logic signals (ECL referenced to a +5 V supply) into an analog laser diode drive current. Receiver Section The receiver of the HFBR-53D3 includes a silicon PIN photodiode mounted together with a custom, silicon bipolar transimpedance preamplifier IC in an OSA. This OSA is mated to a custom silicon bipolar circuit that provides postamplification and quantization. The HFCT-53D3 utilizes an InP PIN photodiode in the same configuration.

The post-amplifier also includes a Signal Detect circuit which provides a PECL logic-high output upon detection of a usable input optical signal level. This singleended PECL output is designed to drive a standard PECL input through a 50 W PECL load.
Recommended Cleaning/ Degreasing Chemicals Alcohols: methyl, isopropyl, isobutyl. Aliphatics: hexane, heptane. Other: soap solution, naphtha. Do not use partially halogenated hydrocarbons such as 1,1.1 trichloroethane, ketones such as MEK, acetone, chloroform, ethyl acetate, methylene dichloride, phenol, methylene chloride, or N-methylpyrolldone. Also, Agilent does not recommend the use of cleaners that use halogenated hydrocarbons because of their potential environmental harm.
to the outside of the equipment chassis it may be subject to whatever system-level ESD test criteria that the equipment is intended to meet. The transceiver performance is more robust than typical industry equipment requirements of today. Electromagnetic Interference (EMI) Most equipment designs utilizing these high-speed transceivers from Agilent will be required to meet the requirements of FCC in the United States, CENELEC EN55022 (CISPR 22) in Europe and VCCI in Japan. Refer to EMI section (page 5) for more details. Immunity Equipment utilizing these transceivers will be subject to radio-frequency electromagnetic fields in some environments. These transceivers have good immunity to such fields due to their shielded design. Eye Safety These laser-based transceivers are classified as AEL Class I (U.S. 21 CFR(J) and AEL Class 1 per EN 60825-1 (+A11). They are eye safe when used within the data sheet limits per CDRH. They are also eye safe under normal operating conditions and under all reasonably foreseeable single fault conditions per EN60825-1. Agilent has tested the transceiver design for compliance with the requirements listed below under normal operating conditions and under single fault conditions where applicable. TUV Rheinland has granted certification to these transceivers for laser eye safety and use in EN 60950 and EN 60825-2 applications. Their performance enables the transceivers to be used without concern for eye safety up to 7 V transmitter VCC.
Package and Handling Instructions
Flammability The HFBR/HFCT-53D3 transceiver housing is made of high strength, heat resistant, chemically resistant, and UL 94V-0 flame retardant plastic. Recommended Solder and Wash Process The HFBR/HFCT-53D3 is compatible with industry-standard wave or hand solder processes. Process plug This transceiver is supplied with a process plug (HFBR-5000) for protection of the optical ports within the duplex SC connector receptacle. This process plug prevents contamination during wave solder and aqueous rinse as well as during handling, shipping and storage. It is made of a hightemperature, molded sealing material that can withstand +80C and a rinse pressure of 110 lbs per square inch. Recommended Solder fluxes Solder fluxes used with the HFBR/HFCT-53D3 should be water-soluble, organic fluxes. Recommended solder fluxes include Lonco 3355-11 from London Chemical West, Inc. of Burbank, CA, and 100 Flux from Alpha-Metals of Jersey City, NJ.
Regulatory Compliance
(See the Regulatory Compliance Table for transceiver performance) The overall equipment design will determine the certification level. The transceiver performance is offered as a figure of merit to assist the designer in considering their use in equipment designs. Electrostatic Discharge (ESD) There are two design cases in which immunity to ESD damage is important. The first case is during handling of the transceiver prior to mounting it on the circuit board. It is important to use normal ESD handling precautions for ESD sensitive devices. These precautions include using grounded wrist straps, work benches, and floor mats in ESD controlled areas. The transceiver performance has been shown to provide adequate performance in typical industry production environments. The second case to consider is static discharges to the exterior of the equipment chassis containing the transceiver parts. To the extent that the duplex SC connector receptacle is exposed

APPLICATION SUPPORT Optical Power Budget and Link Penalties
The worst-case Optical Power Budget (OPB) in dB for a fiberoptic link is determined by the difference between the minimum transmitter output optical power (dBm avg.) and the lowest receiver sensitivity (dBm avg.). This OPB provides the necessary optical signal range to establish a working fiber-optic link. The OPB is allocated for the fiber-optic cable length and the corresponding link penalties. For proper link performance, all penalties that affect the link performance must be accounted for within the link optical power budget.
As for the receiver section, it is internally ac-coupled between the preamplifier and the postamplifier stages. The actual Data and Data-bar outputs of the postamplifier are dc-coupled to their respective output pins (pins 2, 3). Signal Detect is a single-ended, +5 V PECL output signal that is dc-coupled to pin 4 of the module. Signal Detect should not be accoupled externally to the follow-on circuits because of its infrequent state changes. Caution should be taken to account for the proper interconnection between the supporting Physical Layer integrated circuits and this HFBR/HFCT-53D3 transceiver. Figure 3 illustrates a recommended interface circuit for interconnecting to a +5 V dc PECL fiber-optic transceiver. Some fiber-optic transceiver suppliers' modules include internal capacitors, with or without 50 Ohm termination, to couple their Data and Data-bar lines to the I/O pins of their module. When designing to use these type of transceivers along with Agilent transceivers, it is important that the interface circuit can accommodate either internal or external capacitive coupling with 50 Ohm termination components for proper operation of both transceiver designs. The internal dc-coupled design of the HFBR/HFCT-53D3 I/O connections was done to provide the designer with the most flexibility for interfacing to various types of circuits.
In the HFBR-53D3 there are three key elements to the laser driver safety circuitry: a monitor diode, a window detector circuit and direct control of the laser bias. The window detection circuit monitors the average optical power using the monitor diode. If a fault occurs such that the transmitter dc regulation circuit cannot maintain the preset bias conditions for the laser emitter within 20%, the transmitter will automatically be disabled. Once this has occurred, only an electrical power reset will allow an attempted turn-on of the transmitter. The HFCT-53D3 utilizes an integral fiber stub along with a current limiting circuit to guarantee eye-safety. It is intrinsically eye safe and does not require shut down circuitry.
Data Line Interconnections
Agilent's HFBR/HFCT-53D3 fiberoptic transceiver is designed to directly couple to +5 V PECL signals. The transmitter inputs are internally dc-coupled to the laser driver circuit from the transmitter input pins (pins 7, 8). There is no internal, capacitivelycoupled 50 Ohm termination resistance within the transmitter input section. The transmitter driver circuit for the laser light source is a dc-coupled circuit. This circuit regulates the output optical power. The regulated light output will maintain a constant output optical power provided the data pattern is reasonably balanced in duty factor. If the data duty factor has long, continuous state times (low or high data duty factor), then the output optical power will gradually change its average output optical power level to its preset value.
Signal Detect
The Signal Detect circuit provides a deasserted output signal that implies the link is open or the transmitter is OFF. The Signal Detect threshold is set to transition from a high to low state between the minimum receiver input optional power and -30 dBm avg. input optical power indicating a definite optical fault (e.g. unplugged connector for the receiver or transmitter, broken fiber, or failed far-end transmitter or data source). A Signal Detect indicating a working link is functional when receiving encoded 8B/l0B characters. The Signal Detect does not detect receiver data error or error-rate. Data errors are determined by Signal processing following the transceiver.
Eye Safety Circuit
For an optical transmitter device to be eye-safe in the event of a single fault failure, the transmitter must either maintain normal, eyesafe operation or be disabled.

Electromagnetic Interference (EMI)
One of a circuit board designer's foremost concerns is the control of electromagnetic emissions from electronic equipment. Success in controlling generated Electromagnetic Interference (EMI) enables the designer to pass a governmental agency's EMI regulatory standard; and more importantly, it reduces the possibility of interference to neighboring equipment. There are three options available for the HFBR-53D3 and two for the HFCT-53D3 with regard to EMI shielding which provide the designer with a means to achieve good EMI performance. The EMI performance of an enclosure using these transceivers is dependent on the chassis design. Agilent encourages using standard RF suppression practices and avoiding poorly EMI-sealed enclosures. The first configuration is a standard HFBR-53D3 fiber optic transceiver that has no external EMI shield. This unit is for applications where EMI is either not an issue for the designer, the unit resides completely inside a shielded enclosure, or the module is used in a low density, extremely quiet application. The HFCT-53D3 is not available for use without an external shield. The second configuration, option EM, is for EMI shielding applications where the position of the transceiver module will extend outside the equipment enclosure. The metallized plastic package and integral external metal shield of the transceiver helps locally to terminate EM fields to the chassis to prevent their emissions outside the enclosure. This metal shield
contacts the panel or enclosure on the inside of the aperture on all but the bottom side of the shield and provides a good RF connection to the panel. This option can accommodate various panel or enclosure thickness, i.e., .04 in. min. to 0.10 in. max. The reference plane for this panel thickness variation is from the front surface of the panel or enclosure. The recommended length for protruding the HFBR/HFCT-53D3 EM transceiver beyond the front surface of the panel or enclosure is 0.25 in. With this option, there is flexibility of positioning the module to fit the specific need of the enclosure design. (See Figure 6 for the mechanical drawing dimensions of this shield.) The third configuration, option FM, is for applications that are designed to have a flush mounting of the module with respect to the front of the panel or enclosure. The flush-mount design accommodates a large variety of panel thickness, i.e., 0.04 in. min. to 0.10 in. max. Note the reference plane for the flushmount design is the interior side of the panel or enclosure. The recommended distance from the centerline of the transceiver front solder posts to the inside wall of the panel is 0.55 in. This option contacts the inside panel or enclosure wall on all four sides of this metal shield. See Figure 8 for the mechanical drawing dimensions of this shield. The two metallized designs are comparable in their shielding effectiveness. Both design options connect only to the equipment chassis and not to the signal or logic ground of the circuit board within the
equipment closure. The front panel aperture dimensions are recommended in Figures 7 and 9. When layout of the printed circuit board is done to incorporate these metal-shielded transceivers, keep the area on the printed circuit board directly under the metal shield free of any components and circuit board traces. For additional EMI performance advantage, use duplex SC fiber-optic connectors that have low metal content inside them. This lowers the ability of the metal fiber-optic connectors to couple EMI out through the aperture of the panel or enclosure.

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause catastrophic damage to the device. Limits apply to each parameter in isolation, all other parameters having values within the recommended operating conditions. It should not be assumed that limiting values of more than one parameter can be applied to the product at the same time. Exposure to the absolute maximum ratings for extended periods can adversely affect device reliability.
