Transmitter Section
The transmitter section consists of a 1310 nm InGaAsP laser in an eye safe optical subassembly (OSA) which matesto 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 InGaAs PIN 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 normallyused by the system for the diagnostic purpose. The signal is operated in LVTTL level.
