Receiver Signal Detect
Signal Detect is a basic fiber failure indicator. This is a
single-ended PECL output. As the input optical power
is decreased, Signal Detect will switch from high to low
(deassert point) somewhere between sensitivity and
the no light input level. As the input optical power is
increased from very low levels, Signal Detect will switch
back from low to high (assert point). The assert level will be
at least 0.5 dB higher than the deassert level.
Transceiver Specified for Wide Temperature Range Operation
The AFCT-5805xxZ is specified for operation over ex-
tended temperature range of -40° to +85°C.
Characterization of the parts has been performed over
the ambient operating temperature range in an airflow
of 2 m/s.

Applications Information
Typical BER Performance of Receiver versus Input Optical
Power Level
The AFCT-5805xxZ transceiver can be operated at
Bit-Error-Rate conditions other than the required BER =
1 x 10
Standard. The typical trade-off of BER versus Relative In-
put Optical Power is shown in Figure 2. The Relative Input
Optical Power in dB is referenced to the actual sensitivity
of the device. For BER conditions better than 1 x 10
more input signal is needed (+dB).
