Transmitter Section
The transmitter section includes a 1310 nm Fabry-Perot
laser and a transmitter driver circuit. The driver circuit
maintains a constant optical power level provided that
the data pattern is valid 8B/10B code. Connection to
the transmitter is provided via a LC optical connector.
The transmitter has full IEC 60825 and CDRH Class 1 eye
safety.
TX_DISABLE
The transmitter output can be disabled by asserting
pin 3, TX_DISABLE. A high signal asserts this function
while a low signal allows normal laser operation. In
addition, via the 2-wire serial interface the transmitter
output can be disabled (address A2h, byte 110, bit 6) or
monitored (address A2h, byte 110, bit 7). The contents
of A2h, byte 110, bit 6 are logic OR’d with hardware Tx_
Disable (pin 3) to control transmitter operation. In the
event of a transceiver fault, such as the activation of the
eye safety circuit, toggling of the TX_DISABLE will reset
the transmitter, as depicted in Figure 4.
