Description

General Transmitter Section

The transmitter section consists

of a 1300 nm Laser in an eye safe

optical subassembly, (ELSA),

which mates to the fiber cable.

The ELSA is driven by a custom

silicon bipolar IC which converts

differential PECL logic signals,

ECL referenced to a +5 V supply,

into an analog Laser Diode drive

current.

Eye Safety Design

The ELSA is designed to be eye

safe under a single fault condi-

tion. To be eye-safe, only one of

two results can occur in the event

of a single fault. The transmitter

must either maintain a safe level

of output power or the trans-

mitter should be disabled.

The ELSA contains a patented

optical fiber stub which restricts

the level of light emerging from

the connector port under all

conditions. Overdriving the laser

(even to destruction) cannot

produce enough light to violate

the IEC safe level. As a result the

HFCT-5305 is intrinsically eye

safe.

Receiver Section

The receiver includes an InP PIN

photodiode mounted together

with a custom silicon bipolar

transimpedance preamplifier IC

in an optical subassembly, OSA.

This OSA is mated to a custom

silicon bipolar circuit providing

post-amplification and

quantization.

The custom silicon bipolar circuit

also includes a Signal Detect

circuit which provides a PECL

logic high output upon detection

of a usable input optical signal

level. This single-ended low-

power PECL output is designed

to drive a standard PECL input
