The product offers digital diagnostics using the 2-wire
serial interface defined in the XFP MSA. The product
provides real time temperature (module and laser),
supply voltage, laser bias current, laser average output
power and received input power. The digital diagnostic
interface also adds the ability to disable the transmitter
(TX_DIS), power down the module, monitor for module
faults and monitor for Receiver Loss of Signal (RX_LOS).
Transmitter disable, interrupt, power down/reset, receiver
loss of signal and module not ready are also hard wired
pins on the 30-pin right angle connector.
Installation
The AFCT-711XPDZ is hot-pluggable, allowing the
module to be installed while the host system is operating
and on-line. The attach heatsink is designed to clip on to
the XFP cage without a module present.
Upon insertion, the transceiver housing makes initial
contact with the host board XFP cage, mitigating
potential damage due to Electro-Static Discharge (ESD).
Once fully inserted into the XFP cage, the top surface of
the XFP module makes contact with the heatsink through
a cutout in the top of the cage ensuring an effective
thermal path for module heat.

Functional Description
Transmitter Section
The transmitter section includes a 1310 nm DFB (Distrib-
uted Feedback Laser) light source, a transmitter driver
circuit and a signal conditioner circuit on the TX data
inputs. (See Figure 1) Optical connection to the transmit-
ter is provided via a LC connector. The optical output is
controlled by a custom IC that detects the laser output
via the monitor photodiode. This IC provides both dc and
AC current drive to the laser to ensure correct modula-
tion, eye diagram and extinction ratio over temperature,
supply voltage and operating life.
TX_DIS
Asserting pin 5, TX_DIS, will disable the transmit-
ter optical output. The transmitter output can also
be disabled and monitored via the two-wire serial
interface.
Eye Safety Circuit
Under normal operating conditions laser power will be
maintained below Class 1 eye-safety limits.
