Transmitter Section
The transmitter section consists of a 1550 nm InGaAsP laser in an eye safe optical subassembly (OSA) which mates to the fiber
cable. The laser OSA is driven by a LD driver IC which converts differential input LVPECL logic signals into an analog laser
driving current.
TX_DISABLE
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”).
Receiver Section
The receiver utilizes an APD photodiode mounted together with a trans-impedance preamplifier IC in an OSA. This OSA is
connected to a circuit providing post-amplification quantization, and optical signal detection.
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 LVTTL level..
