The lead-free and RoHS-compliant small form factor pluggable (SFP+) transceiver from JDSU improves the performance for 8 Gigabit Fibre Channel (8GFC) applications, and is ideal for high-speed, storage area network applications. This transceiver features a highly reliable, distributed-feedback (DFB) laser coupled to an LC optical connector. The transceiver is fully compliant to the FC-PI-4 800-SMLC-L variant and is compatible with 400-SM-LC-L and 200-SM-LC-L variants. It is fully compatible with SFP+ specifications at 8.5 G, 4.25 G and 2.125 G bit rates, with internal AC coupling on both transmit and receive data signals. The all-metal housing design provides low EMI emissions in demanding 8.5 G applications and conforms to IPF specifications. An enhanced digital diagnostic feature set allows for real-time monitoring of transceiver performance and system stability, and the serial ID allows for customer and vendor system information to be stored in the transceiver. Transmit disable, loss-of-signal, and transmitter fault functions are also provided. The small size of the transceiver allows for high-density system designs that, in turn, enable greater total bandwidth.

8.5 G F IBRE CHANNEL COMPLIANT SFP+ 1310 NM LIMITING TRANSCEI vER
2 Section 1 Functional Description
TheJSH-85L3Ax1-108.5GSFP+1310nmopticaltransceiverisdesignedtotransmit and receive 8B/10B scrambled 8.5 G serial optical data over standard single-mode optical fiber.
Transmitter
The transmitter converts 8B/10B scrambled serial PECL or CML electrical data into serial optical data compliant with the 800-SM-LC-L variant of the 8 G Fibre Channel standard. Transmit data lines (TD+ and TD-) are internally AC coupled, with 100 W differential termination. Transmitterrateselect(RS1)pin9isassignedtocontroltheSFP+moduletransmitterrate.Itisconnectedinternallytoa30kW pull-down resistor. A data signal on this pin does not affect the operation of the transmitter. Anopencollector-compatibletransmitdisable(Tx_Disable)isprovided.Thispin is internally terminated with a 10 kWresistortoVcc,T. A logic "1," or no connection, on this pin will disable the laser from transmitting. A logic "0" on this pin provides normal operation. The transmitter has an internal PIN monitor diode that ensures constant optical power output, independent of supply voltage. It is also used to control the laser output power over temperature to ensure reliability at high temperatures. Anopencollector-compatibletransmitfault(Tx_Fault)isprovided.TheTx_Fault signal must be pulled high on the host board for proper operation. A logic "1" output from this pin indicates that a transmitter fault has occurred or that the part is not fully seated and the transmitter is disabled. A logic "0" on this pin indicates normal operation.
Receiver
The receiver converts 8B/10B scrambled serial optical data into serial PECL/CML electrical data. Receive data lines (RD+ and RD-) are internally AC coupled with 100 W differential source impedance, and must be terminated with a 100 W differential load. ReceiverRateSelect(RS0)pin7isassignedtocontroltheSFP+modulereceiver rate.Itisconnectedinternallytoa30kW pull-down resistor. A data signal on this pin has no affect on the operation of the receiver. An open collector compatible loss of signal (LOS) is provided. The LOS must be pulled high on the host board for proper operation. A logic "0" indicates that light has been detected at the input to the receiver (see Optical Characteristics, Loss of Signal Assert/Deassert Time). A logic "1" output indicates that insufficient light has been detected for proper operation.

PECL driver and receiver components will require biasing networks. Please consult application notes from suppliers of these components. CML I/O on the PHY are supported. Good impedance matching for the driver and receiver is required. SDA and SCL should be bi-directional open collector connections in order to implement serial ID in JDSU SFP+ transceiver modules.

Digital Diagnostic Monitoring and Serial ID Operation
TheJSH-85L3Ax1-10opticaltransceiverisequippedwithatwo-wireserialEEPROM that is used to store specific information about the type and identification of the transceiver as well as real-time digitized information relating to the transceiver's performance. See the Small Form Factor Committee document number SFF-8472Revision10.3,datedDecember1,2007formemory/addressorganization of the identification data and digital diagnostic data. The enhanced digital diagnostics feature monitors five key transceiver parameters which are internally calibrated and should be read as absolute values and interpreted as follows:

Reading the data
The information is accessed through the SCL and SDA connector pins of the module. The SFF-8431 Revision 3.2 specification contains all the timing and addressing information required for accessing the data in the EEPROM. ThedeviceaddressusedtoreadtheSerialIDdatais1010000X(A0h),andthe addresstoreadthediagnosticdatais1010001X(A2h).Anyotherdeviceaddresses will be ignored. MOD_ABS, pin 6 on the transceiver, is connected to Logic 0 (Ground) on the transceiver. SCL, pin 5 on the transceiver, is connected to the SCL pin of the EEPROM. SDA, pin 4 on the transceiver, is connected to the SDA pin of the EEPROM. The EEPROMWrite Protect pin is internally tied to ground with no external access,allowingwriteaccesstothecustomer-writablefield(bytes128-247of address1010001X).Note:addressbytes0-127arenotwriteprotectedandmay cause diagnostic malfunctions if written over.
Decoding the data
The information stored in the EEPROM, including the organization and the digital diagnostic information, is defined in the Small Form Factor Committee documentSFF-8472Revision10.3,datedDecember1,2007.

4.2 Package and Handling Instructions
This product is not compatible with any aqueous wash process.
Process plug
TheJSH-85L3Ax1-10opticaltransceiverissuppliedwithaprocessplug.Thisplug protects the transceiver optics during standard manufacturing processes by preventing contamination from air borne particles. Note: It is recommended that the dust cover remain in the transceiver whenever an optical fiber connector is not inserted.
Recommended cleaning and degreasing chemicals
JDSU recommends the use of methyl, isopropyl and isobutyl alcohols for cleaning. Do not use halogenated hydrocarbons (trichloroethane, ketones such as acetone, chloroform, ethyl acetate, MEK, methylene chloride, methylene dichloride, phenol, N-methylpyrolldone).
Flammability
The housing is made of cast zinc and sheet metal.
4.3 Electrostatic Discharge (ESD)
Handling
Normal ESD precautions are required during the handling of this module. This transceiver is shipped in ESD protective packaging. It should be removed from the packaging and handled only in an ESD protected environment utilizing standard grounded benches, floor mats, and wrist straps.
Test and operation
In most applications, the optical connector will protrude through the system chassis and be subjected to the same ESD environment as the system. Once properly installed in the system, this transceiver should meet and exceed common ESD testing practices and fulfill system ESD requirements. Typical of optical transceivers, this module's receiver contains a highly sensitive optical detector and amplifier which may become temporarily saturated during an ESD strike. This could result in a short burst of bit errors. Such an event may require the application to reacquire synchronization at the higher layers (serializer/deserializer chip).

4.4 Eye Safety
TheJSH-85L3Ax1-10OpticalTransceiverisaCLASS1LASERPRODUCTasdefinedbytheinternationalstandardIEC60825-1SecondEdition2007-03andby U.S.A. regulations for Class 1 products per CDRH 21 CFR 1040.10 and 1040.11. Laser emissions from Class 1 laser products are not considered hazardous when operated according to product specifications. Operating the product with a power supplyvoltageexceeding4.0voltsmaycompromisethereliabilityoftheproduct, andcouldresultinlaseremissionsexceedingClass1limits.
Caution
Tampering with this laser based product or operating this product outside the limits of this specification may be considered an act of "manufacturing," and will require, under law, recertification of the modified product with the U.S. Food and Drug Administration (21 CFR 1040). The use of optical instruments with this product will increase eye hazard.
