Transmitter
Preliminary Technical Data
XMT5370-622
Features
Description
• SONET/SDH Compliant to
STM4 I-4, S-4.1
OC12 SR, IR.1
• –40°C to +85°C Operation
• Compact 20 Pin Package
• ECL/PECL Logic Interface
• Multisourced Pinout
The XMT5370-622 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 622 MBd
transmission.
Applications
• SONET/SDH Systems
• Fiber to the Home
• Data Communications
Networks
The transmitter incorporates
several features which simplify
system design. The
XMT5370-622 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 adjustments are necessary. Finally, a
laser disable input is provided to
shut down the laser for standby
or test purposes.
The XMT5370-622 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.

MONITOR
The module provides the
necessary bias and modulation
control to maintain the extinction
ratio at better than 8.2 dB and
the waveform is compliant with
SONET/SDH Eyemask standard
G.957.
The laser bias control loop
compensates for temperature
induced variations in laser
performance. The bias current
monitor indicates the amount of

(This is approximately the laser

The rear facet monitor is a signal

of a HI/LO light alarm.
In the absence of data the laser
will emit a mean optical power
within the specified limits. The
extinction ratio and duty cycle
distortion are specified assuring a
50% duty cycle at the correct

Description
The XMT5360-155 and
XMT5160-155 are high
performance uncooled optical
laser transmitters for CCITT SDH
and ANSI SONET applications.
They are designed with an
ECL/PECL logic interface for
155 Mb/s transmission.
448
The transmitters incorporate
several features which simplify
system design. They may be
operated with either +5 V or –5 V

The compact transmitter module
contains a pigtailed laser, data

external components or adjustments are necessary. Finally, a
laser disable input is provided to
shut down the laser for standby
or test purposes.
The two variants of the
transmitter are for intermediate
and long haul applications. The
XMT5360-155 has –10 dBm
mean output power for short and
intermediate reach systems and
the XMT5160-155 has –2.5 dBm
mean output power for long haul
systems. The two versions are
fully interchangeable to allow a
single board design to be configured for short, intermediate,
and long haul applications.
The XMT5360-155 and
XMT5160-155 include 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
transmitters are packaged in a
20 pin 0.4" pitch DIP. An
evaluation board is available for
this product. Contact your local

Contact Hewlett-Packard for details.
3. Other output power options are available. Contact Hewlett-Packard for details.
4. Common mode signal 3.5 V nominal.
5. Common mode signal 4.0 V nominal.
6. With VEE connected to –5 V, VCC must be at 0 V. With V CC at +5 V, VEE must be at 0 V.
7. End of life at Tmax.
