AFBR-0545Z Fast Ethernet Media Converter Board

with the AFBR-5972Z Transceiver

Application Note 5549

Introduction

The Avago AFBR-5972Z transceiver module enables

system designer to implement a 100 Mbps Fast Ethernet

data link over standard plastic optical fiber (POF, NA =

0.5). The AFBR-0545Z media converter board allows a

system designer to quickly evaluate AFBR-5972Z trans-

ceiver module performance. The transceiver module

can be connected with Avago Versatile Link connectors

(AFBR-4526Z).The AFBR-5972Z module is lead free and

RoHS compatible.

AFBR-0545Z Media Converter Kit

The media converter kit includes:

1. Media converter board (2 pieces)

2. 12V DC power supply (2 pieces) plus power supply

adapter (5 types, 2 pieces each)

3. 2 meter POF Cable (NA = 0.5) with duplex connector for

the AFBR-5972Z (P/N HFBR-RSD002Z)

4. CAT 5 patch cable (2 pieces)

5. AFBR-0545Z application note

As shown in Figure 1, the media converter board includes

a twisted pair interface, optical transceiver module, a

media converter PHY chip, and power supply interface.

The media converter PHY chip translates the data signal

from the twisted pair domain to the optical domain.

POF cable has many significant advantages over twisted

pair copper media.

 Optical cable is immune to, and does not generate, EM

fields.

 Complete galvanic isolation is also achieved using

optical communication links.

 Plastic optical fiber (POF) also offers a lower weight

media.

 POF offers a low cost cable solution and easy field

termination.
