Description

General

The HFBR-5208xxxZ (multimode transceiver) from Avago

allow the system designer to implement a range of solu-

tions for ATM/SONET STS-12/SDH STM-4 applications.

The overall Avago transceiver consists of three sections:

the transmitter and receiver optical subassemblies, an

electrical subassembly and the mezzanine package

housing which incorporates a duplex SC connector

receptacle.

Transmitter Section

The transmitter section of the HFBR-5208xxxZ consists

of a 1300 nm LED in an optical subassembly (OSA) which

mates to the multimode fiber cable. The OSA’s are driven

by a custom, silicon bipolar IC which converts differential

PECL logic signals (ECL referenced to a +5 V supply) into

an analog LED drive current.

Receiver Section

The receiver contains an InGaAs PIN photodiode mounted

together with a custom, silicon bipolar transimpedance

preamplifier IC in an OSA. This OSA is mated to a custom,

silicon bipolar circuit providing post amplification and

quantization and optical signal detection.

The custom, silicon bipolar circuit includes a Signal Detect

circuit which provides a PECL logic high state output

upon detection of a usable input optical signal level. This

single-ended PECL output is designed to drive a standard

PECL input through normal 50 W PECL load.
