Digital Diagnostic Functions
WS-G5487-C support the 2-wire serial communication protocol. Digital diagnostic information are
accessible over the 2-wire interface at the address 0xA2. Digital Diagnostics for WS-G5487-C are
internally calibrated by default. A micro controller unit inside the transceiver gathers the monitoring
information and reports the status of transceiver.
Transceiver Temperature, internally measured, represented as a 16 bit signed twos complement
value in increments of 1/256 degrees Celsius, Temperature accuracy is better than ±3 degrees
Celsius over specified operating temperature and voltage.
Transceiver Supply Power, internally measured, represented as a 16 bit unsigned integer with the
voltage defined as the full 16 bit value (0 – 65535) with LSB equal to 100 µVolt, yielding a total range
of 0 to +6.55 Volts.
Transceiver TX bias current, internally measured, represented as a 16 bit unsigned integer with the
current defined as the full 16 bit value (0 – 65535) with LSB equal to 2 µA, yielding a total range of 0
to 131mA. Accuracy is better than ±10% over specified operating temperature and voltage.
Transceiver TX output power, internally measured, represented as a 16 bit unsigned integer with
the power defined as the full 16 bit value (0 – 65535) with LSB equal to 0.1 µW. Data is assumed to
be based on measurement of laser monitor photodiode current. Accuracy is better than ±3dB over
specified temperature and voltage. Data is not valid when the transmitter is disabled.
Transceiver RX received optical power, internally measured, represented as a 16 bit unsigned
integer with the power defined as the full 16 bit 35 value (0 – 65535) with LSB equal to 0.1 µW.
Accuracy is better than ±3dB over specified temperature and voltage.

OPTICAL SUBASSEMBLY
Transmitter Section
The DFB driver accept differential input data and provide bias and modulation currents for driving a
laser. An automatic power-control (APC) feedback loop is incorporated to maintain a constant
average optical power. 1550 nm DFB in an eye safe optical subassembly (OSA) mates to the fiber
cable.
TX_DISABLE
The TX_DISABLE signal is high (TTL logic “1”) to turn off the laser output. The laser will turn on within
1ms when TX_DISABLE is low (TTL logic “0”).
TX_FAULT
When the TX_FAULT signal is high, output indicates a laser fault of some kind. Low indicates normal
operation.
Receiver Section
The receiver utilizes a PIN detector integrated with a trans-impedance preamplifier in an OSA. This
OSA is connected to a Limiting Amplifier which providing post-amplification quantization, and optical
signal detection. The limiting Amplifier is AC-coupled to the transimpedance amplifier, with internal
100Ω differential termination.
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.
Controller Section
The micro controller unit monitors the operation information of LD driver and Limiting Amplifier. And
report these status to the customer.
