Fiber Optic Transceiver For Fast Ethernet

Data Sheet

Application

Optical Transceiver for Fast Ethernet over POF

Features

The Avago high speed ber optical transceiver for Fast
Ethernet is an excellent solution for converting high
speed binary data to dierential digital data.

• Data rate up to 100Mbit/s (125MBaud)

• Integrated EMI shielding

• Operating temperature range 0°C to 70°C

• Operating @ 3.3V Power Supply

• Bare ber header (which supports thin and exible Plastic

Optical Fiber (POF) with 1.5mm outer jacket diameter)
integrated. Fiber pull out strength >20N (Ta = 25°C)

• Green package (lead free and halogen free)

• 650nm LED with integrated driving circuit (logic to

light)

• No light toggling of the LED at no signals on the input

data lines

Description

The 8-pin Optical Transceiver is a highly integrated CMOS
IC combined with a high speed photodiode and LED
designed to receive and transmit up to 125Mbit/s optical
data which can be 4b5b or 8b10b coded (up to 125Mbit/
s). The internal peaking and clamping circuit will yield an
ideal eye-opening.

Safety Hints

Applications of new chip technologies lead to increasing optical eciency and growing and higher
levels of optical performance. We therefore recommend that the current versions of the IEC 60825-1 and
EN 60825-1 standards are taken into account right from the outset, i.e. at the equipment development stage, and
that suitable protection facilities are provided.
