Figure 1. Transceiver functional diagram
Transmit Fault (TX_FAULT)
A catastrophic laser fault will activate the transmitter
signal, TX_FAULT, and disable the laser. This signal is
an open collector output (pull-up required on the host
board). A low signal indicates normal laser operation and
a high signal indicates a fault. A fault is dened as laser
power below or above the specied IEEE 802.3ae speci-
ed min/max range. The TX_FAULT will be latched high
when a laser fault occurs and is cleared by toggling the
TX_DISABLE input or power cycling the transceiver. The
transmitter fault condition can also be monitored via the
two-wire serial interface (address A2, byte 110, bit 2).
Transmitter Section
The transmitter section includes the Transmitter Optical
Sub-Assembly (TOSA) and laser driver circuitry. The
TOSA, containing an Avago designed and manufactured
1310 nm DFB light source, is located at the optical inter-
face and mates with the LC optical connector. The TOSA
is driven by an IC which uses the incoming dierential
high speed logic signal to modulate the laser diode
driver current. This Tx laser driver circuit regulates the
optical power at a level within the specied range.
Transmit Disable (TX_DISABLE)
The AFCT-701SDDZ accepts an LVTTL compatible trans-
mit disable control signal input which shuts down the
transmitter optical output. A high signal implements
this function while a low signal allows normal transceiver
operation. In the event of a fault (e.g. eye safety circuit
activated), cycling this control signal resets the module
as depicted in Figure 5. An internal pull up resistor dis-
ables the transceiver transmitter until the host pulls the
input low. TX_DISABLE can also be asserted via the two-
wire interface (address A2h, byte 110, bit 6) and moni-
tored (address A2h, byte 110, bit 7).
The contents of A2h, byte 110, bit 6 are logic OR’d with
hardware TX_DISABLE (contact 3) to control transmitter
operation. The normal behavior of this feature is to reset
a TX disabled transceiver to TX enabled when it is power
cycled or hot-plugged.
