RX_LOS
Transmitter and Receiver Optical Sub-assembly Section
A 1550 nm InGaAsP laser and an InGaAs PIN photodiode integrate with an WDM filter to form a bi-directional single fiber
optical subassembly (OSA). The laser of OSA is driven by a LD driver IC which converts differential input LVPECL logic
signals into an analog laser driving current. And, The photodiode of OSA is connected to a circuit providing post-amplification
quantization, and optical signal detection.
TX_FAULT
When sensing an improper power level in the laser driver, the SFP set 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_DISABLE
The TX_DISABLE signal is high (TTL logic “1”) to turn off the laser output.
Receive Loss (RX_LOS)
The RX_LOS is high (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.
