AFCT-57V6USZ
Small Form Factor Pluggable (SFP) LC Optical Transceiver
for 1.25GBd Ethernet at Extended Link Lengths (Up to 80km)
Data Sheet
Description
The Avago Technologies AFCT-57V6USZ transceiver is a
low-cost and hot-pluggable SFP MSA-compliant optical
interconnect module for Gigabit Ethernet applications at
transmission distances up to 80km ^{[1, 2]}.
The AFCT-57V6USZ implements the serial portion of the
physical layer, and supports the features shown below
The AFCT-57V6USZ features differential serial I/O inter-
face lines that are AC-coupled signals. Avago’s design
of the long wavelength SFP module uses a 1550 nm
distributed feedback (DFB) laser diode (LD) and takes
advantage of an integrated preamplifier/photo-detector.
The AFCT-57V6USZ also contains transmitter, receiver and
control electronics.
Singlemode optical fiber, with LC connectors, is rec-
ommended as the communication media. The AFCT-
57V6USZ has a digital diagnostic monitoring (DDM)
function in accordance with SFF-8472 ^[3] which allows
monitoring operating temperature, supply voltage, laser
bias current, transmitter optical output power and optical
received power in real time via a serial-ID interface.
On the following page, Table1 lists the general specifica-
tions for the AFCT-57V6USZ.
