Description

The XMT5170-622 is a high

performance uncooled optical

DFB laser transmitter for CCITT

SDH and ANSI SONET

applications. It is designed with

an ECL/PECL logic interface for

622 MBd transmission.

The transmitter incorporates

several features which simplify

system design. The

XMT5170-622 may be operated

with either +5 V or –5 V power

supplies. Its standard 10 KH ECL

data interface enables direct

interface with PECL or ECL logic.

The compact transmitter module

contains a pigtailed laser, data

interface, bias and modulation

control circuitry. Thus, no

external components or adjust-

ments are necessary. Finally, a

laser disable input is provided to

shut down the laser for standby

or test purposes.

The XMT5170-622 includes

analog outputs which are

proportional to laser current and

optical power. These may be used

with external circuitry to detect

end-of-life, or over temperature

conditions.

The transmitter is packaged in a

20 pin 0.4" pitch DIP. Contact

your local representative for

more details.
