Digital Diagnostic Functions
SFP-1G-LX supports the 2-wire serial communication protocol as defined in SFP MSA.
Digital diagnostic information is accessible over the 2-wire interface at the address 0xA2.
Digital Diagnostics for SFP-1G-LX 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. The laser is packaged in an eye safe optical subassembly
(OSA) which 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 trans
impedance 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 statuses to the customer.
