Product Description
SFP GE BXU SM1310 20KM fiber optic transceiver2.5G/SM/1310/2KM/DDMI transceiver is a high performance, cost effective module that supports data-rate up to 2.67Gbps.The transmitter section and the receiver section work independently in the transceiver. The receiver section contains an InGaAs PIN photo diode, a transimpedance amplifier and a post amplifier (with working data rate up to 2.67Gbps), functionally transmit received optical power to steady electrical data.

Block Diagram of TransceiverTransmitter SectionTX-FAULTTX Fault is an open collector/drain output, which should be pulled up with a 4.7K - 10KΩ 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. When sensing an improper power level in the laser driver, the SFP sets this signal high and turns off the laser. TX-FAULT can be reset with the TX-DISABLE line. The signal is in TTL level.TX-DISABLETX disable is an input that is used to shut down the transmitter optical output. It is pulled up within the module with a 4.7 - 10 KΩ resistor. Its states are: Low (0 - 0.8V): Transmitter on; (>0.8, < 2.0V): Undefined; High (2.0 - 3.465V): Transmitter Disabled; Open: Transmitter Disabled. The TX-DISABLE signal is high (TTL logic "1") to turn off the laser output. The laser will turn on when TX-DISABLE is low (TTL logic "0").TD-/+These are the differential transmitter inputs. They are AC-coupled, differential lines with 100Ω differential terminationinside the module. The AC coupling is done inside the module and is thus not required on the host board. The inputswill accept differential swings of 500 - 2400 mV (250 - 1200 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.Receiver SectionRX-LOSLOS (Loss of Signal) is an open collector/drain output, which should be pulled up with a 4.7K - 10KΩ resistor. Pull up voltage between 2.0V and VccT, R+0.3V. 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 < 0.8V.The RX-LOS is high (TTL logic "1") when there is no incoming light from the companion transceiver. This signal is normally used by the system for the diagnostic purpose. The signal is operated in TTL level.RD-/+These are the differential receiver outputs. They are AC coupled 100Ω differential lines which should be terminated with 100 Ω (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 600 and 1000 mV differential (300 - 500 mV single ended) when properly terminated.Mod-Def 0, 1, 2.Mod-Def 0, 1, 2. These are the module definition pins. They should be pulled up with a 4.7 - 10K resistor on the host board to supply less than VccT+0.3V or VccR+0.3V.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.Recommended host board power supply circuitRecommended Interface CircuitDigital Diagnostic Memory MapCertficate:Exhibition:
