AFCT-57V6NSZ

Small Form Factor Pluggable (SFP) LC Optical Transceiver

for 1.25GBd Ethernet at Extended Link Lengths (Up to 40km)

Data Sheet

Description

The AFCT-57V6NSZ transceiver is a specially customised

low-cost and hot-pluggable SFP MSA-compliant optical

interconnect module for Gigabit Ethernet applications at

transmission distances up to 40km [1, 2].

The AFCT-57V6NSZ implements the serial portion of the

physical layer, and supports the features shown below

The AFCT-57V6NSZ features differential serial I/O inter-

face lines that are AC-coupled signals. Avagoâs 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-57V6NSZ also contains transmitter, receiver

and control electronics.

Singlemode optical fiber, with LC connectors, is rec-

ommended as the communication media. The AFCT-

57V6NSZ 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 opti-

cal received power in real time via a serial-ID interface.

On the following page, Table1 lists the general specifica-

tions for the AFCT-57V6NSZ SFP.

Figure 1 shows a simplified block diagram of the AFCT-

57V6NSZ electronics.
