Digital Diagnostic Functions
SFP-GE-CWDM-xxxx-26DB-C10 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-GE-CWDM-xxxx-26DB-C10 are internally calibrated by default. The internal micro
control unit accesses the device operating parameters in real time,Such as transceiver temperature,
laser bias current, transmitted optical power, received optical power and transceiver supply voltage.The
module implements the alarm function of the SFP MSA,alerts the user when a particular operating
parameter exceeds the factory-set normal range.
Block-Diagram-of-Transceiver
Functions Description
The transmitter is mainly composed of a laser driver part of the intelligent transceiver chip and a TOSA
(light-emitting component). The TOSA includes a DFB laser and a backlight photodetection chip.When
the module is working, the input signal is connected to the intelligent transceiver chip, at this time, the
laser driver of the intelligent transceiver chip supplies the bias current and the modulation current to
the laser.The intelligent transceiver chip simultaneously uses an automatic optical power control (APC)
feedback loop to maintain a constant average optical power of the laser output. The purpose is to eliminate
the change of the output optical signal due to temperature changes and aging of the light source
device.When the transmitter enable pin (TX_Disable) is high (TTL logic "1"), the laser output is turned
off. When TX_Disable is low (TTL logic "0"), the laser will turn on within 1ms.When the transmitter fault
signal (TX_Fault) is reported as high,indicates a transmitter failure caused by the transmitter's bias current
or transmitted optical power or laser tube temperature exceeding a preset alarm threshold. Low
indicates normal operation.
The receiver is mainly composed of a limiting amplifier part of the intelligent transceiver chip and a ROSA
(light-receiving component).The ROSA includes a PIN photodetector and a transimpedance amplifier
chip.When the ROSA detects the incident light signal, it will be converted into a photo-generated current
by the PIN photodetector. The photo-generated current is converted into an electrical signal after
passing through the transimpedance amplifier. The electrical signal is further amplified by the limiting
amplifier , then outputs a fixed-amplitude electrical signal to the host.When the amplitude of the electrical
signal received from the incident light conversion of the opposite optical transceiver module is
lower than the set threshold,the module reports that the received signal is lost,the RX_LOS pin is high
(logic "1"),which can be used to diagnose whether the physical signal is normal.The signal is operated
in TTL level.The microprocessor inside the module monitors the module's operating voltage, temperature,
transmitted optical power, received optical power, and laser bias current value in real time. The
host acquires this information over a 2-wire serial bus.
