HFCT-5201

155 Mb/s Single Mode Fiber Transceiver

for ATM, SONET OC-3/SDH STM-1

Part of the Avago METRAK family

Data Sheet

Description

General

The HFCT‑5201 is a 1300 nm laser based transceiver. It

provides a very cost‑effective solution for medium haul

155 Mb/s data link requirements.

The new multisourced 2 x 9 footprint package style is a

variation of the standard 1 x 9 package with an integral

Duplex SC connector receptacle. The extra row of 9 pins

provides connections for laser bias and optical power

monitoring as well as providing transmitter disable

function. A block diagram is shown in Figure 1.

Transmitter Section

The transmitter section of the HFCT‑5201 consists of a

1300 nm InGaAsP laser in an eyesafe optical subassembly

(OSA) which mates to the fiber cable. The laser OSA is

driven by a custom, silicon bipolar IC which converts dif‑

ferential input PECL logic signals, ECL referenced to a +5

V supply, into an analog laser drive current.

The laser bias monitor circuit is shown in Figure 2a, the

power monitor circuit in Figure 2b.

Receiver Section

The receiver utilizes an InGaAs PIN photodiode mounted

together with a silicon bipolar transimpedance preampli‑

fier IC in an OSA. This OSA is connected to a silicon bipolar

circuit providing post‑ amplification quantization, and

optical signal detection.

The post amp circuit includes a Signal Detect circuit

which provides a PECL logic‑high output upon detection

of a usable input optical signal level. Signal Detect is

a basic fiber failure indicator. This single‑ended PECL

output is designed to drive a standard PECL input.
