Description
The XMT5370-155 is a high
performance uncooled optical
laser transmitter for CCITT SDH
and ANSI SONET applications. It
is designed with an ECL/PECL
logic interface for 155 MBd
transmission.
The transmitter incorporates
several features which simplify
system design. It may be
operated with either +5 V or –5 V
power supplies. 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 XMT5370-155 has -11 dBm
mean output power for short and
intermediate reach systems.
The XMT5370-155 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. An
evaluation board is available for
this product. Contact your local
representative for more details.
