Agilent HFCT-5710L/LP Small Form Factor Pluggable LC Optical Transceivers
Data Sheet
Description The HFCT-5710L/LP Small Form Factor Pluggable LC optical transceiver is compliant with both the IEEE 802.3Z (1000BASE-LX) and Small Form Factor Pluggable (SFP) MultiSource Agreement (MSA) specifications. The transceiver is intended for premise, public and access networking equipment. The product transmits data over single mode cable for a link distance of 10 km, which is in excess of the standard. Typical applications for this product are switch to switch, switch backbones, and highspeed interface for server farms. Emerging applications of this product include high-density metro access switch GbE connections.

General Features 1000BASE-LX Compliance: The HFCT-5710L/LP is compliant with the IEEE 802.3Z (2000 Edition) Physical Medium Dependent (PMD) sublayer and baseband medium, type 1000BASE-LX (Long Wavelength Laser) description. This includes specifications for the signal coding, optical fiber and connector types, optical and electrical transmitter characteristics, optical and electrical receiver characteristics, jitter characteristics, and compliance testing methodology for the aforementioned. This transceiver is capable of implementing both Single Mode (SM) and Multimode (MM) optical fiber applications in that order of precedence in the event of conflicting specifications. In addition, the SM link type exceeds the 2 m to 5 km 1000BASE-LX specification by achieving compliance over 2 m to 10 km. The MM link type meets the 50 m and 62.5 m MMF specification when used with an "offset launch" fiber. The optical connector is LC duplex. There is no governing environmental specification in IEEE 802.3Z therefore the environmental specifications contained in this product definition take precedence. Compliance over all operating conditions defined in this document is implied except where specifically noted.
SFP MSA Compliance: The product package is compliant with the SFP MSA with the LC connector option. The SFP MSA includes specifications for mechanical packaging and performance as well as dc, ac and control signal timing and performance. The power supply is 3.3 V dc. The High Speed I/O (HSIO) signal interface is a Low Voltage Differential type. It is ac coupled and terminated internally to the module. The internal termination is a 100 Ohm differential load. Operating Temperature The HFCT-5710L/LP has an operating case temperature of -10 to +85C.
Serial Identification (EEPROM) The HFCT-5710L/LP is compliant with the SFP MSA, which defines the serial identification protocol. This protocol uses the 2-wire serial CMOS E2PROM protocol of the ATMEL AT24C01A or similar. MSA compliant, example contents of the HFCT-5710L/LP serial ID memory are defined in Table 9. Eye Safety For details of product compliance, see Table 1. De-latch Mechanism The de-latching mechanism uses the same design as the MM HFBR-5710L. The HFCT-5710L/ LP is designed with an MSA compliant standard de-latch and an optional de-latch for Belly-toBelly operation. The optional de-latch has been slightly modified outside of MSA compliance to optimize the mechanical performance of the product. These modifications do not interfere with the overall form, fit and function as specified by the SFP MSA. Power Supply Noise The HFCT-5710L/LP can withstand an injection of PSN on the VCC lines of 100 mV ac without a degradation in eye mask margin to 10% on the transmitter and a 1 dB sensitivity penalty on the receiver. This occurs when the product is used in conjunction with the MSA recommended power supply filter shown in Figure 1.

Notes: 1) TX Fault is an open collector/drain output, which should be pulled up with a 4.7K - 10K resistor on the host board. Pull up voltage between 2.0V and VccT, R+0.3V. When high, output indicates a laser fault of some kind. Low indicates normal operation. In the low state, the output will be pulled to < 0.8V. 2. TX Disable input is used to shut down the laser output per the state table below with an external 4.7 - 10 KW pull-up resistor. Low (0 - 0.8 V): Transmitter on Between (0.8 V and 2.0 V): Undefined High (2.0 - 3.465 V): Transmitter Disabled Open: Transmitter Disabled 3. MOD-DEF 0,1,2. These are the module definition pins. They should be pulled up with a 4.7 - 10 KW resistor on the host board to a supply less than VccT +0.3 V or VccR+0.3 V. MOD-DEF 0 is grounded by the module to indicate that the module is present MOD-DEF 1 is clock line of two wire serial interface for optional serial ID MOD-DEF 2 is data line of two wire serial interface for optional serial ID 4. LOS (Loss of Signal) is an open collector/drain output which should be pulled up externally with a 4.7K - 10 KW resistor on the host board to a supply < VccT,R+0.3 V. When high, this output indicates the received optical power is below the worst case receiver sensitivity (as defined by the standard in use). Low indicates normal operation. In the low state, the output will be pulled to < 0.8 V. 5. RD-/+: These are the differential receiver outputs. They are ac coupled 100W differential lines which should be terminated with 100W differential at the user SERDES. The ac coupling is done inside the module and is thus not required on the host board. The voltage swing on these lines will be between 370 and 1600 mV differential (185 - 800 mV single ended) when properly terminated. 6. VccR and VccT are the receiver and transmitter power supplies. They are defined as 3.135 - 3.465 V at the SFP connector pin. The maximum supply current is 300 mA and the associated inrush current will be no more than 30 mA above steady state after 500 nanoseconds. 7. TD-/+: These are the differential transmitter inputs. They are ac coupled differential lines with 100W differential termination inside the module. The ac coupling is done inside the module and is thus not required on the host board. The inputs will accept differential swings of 500 - 2400 mV (250 1000 mV single ended), though it is recommended that values between 500 and 1200 mV differential (250 - 600 mV single ended) be used for best EMI performance.
