Description

Optek’s OPF5020 is a 125Mbps SFF transceiver for use in

data communications applications. It utilizes a MT-RJ dual

fiber receptacle which features a small size and intuitive latch-

ing mechanism design which allows for higher density imple-

mentations and easier end-user installation.

The transmitter is an 850 nm GaAlAs LED, configured for

optimum transceiver performance when used in conjunction

with a low-side driver. The coupling efficiency of the LED and

optical system allows the device to be used at low current

levels, reducing power consumption and increasing system

reliability.

The receiver consists of a high speed PIN photodiode coupled

to a low noise transimpedance amplifier. The receiver output

is a low impedance analog source. The analog representa-

tion of the received optical input can be easily converted to

PECL or TTL levels by external circuitry to be used in digital

modes up to 125Mbps, NRZ.

Combining the OPF5020 with commercially available LED

driver and post amplifier circuits results in a physical layer

medium dependent (PMD) sub-layer for communication be-

tween nodes of a fiber network. Optek Application Bulletin

217 presents an example PMD design with typical receiver

sensitivity of –30dBm at a BER of 2.5 x 10

duplex with either a 2

The OPF5020 has been fully tested in accordance with Bell-

core 468. See Application Bulletin 219 for full details.
