T92-Type 10 Gbits/s 1300 nm
Uncooled DFB Laser Transmitter
■ Laser degrade alarm
■ Clock-select input (next generation)
■ Transmitter disable input
■ SC, FC-PC, and LC optical connector options
Applications
■ Telecommunications:
— SONET/SDH
— Subscriber loop
— Metropolitan area networks
■ High-speed data communications
Offering SONET/SDH compatibility, the T92-Type Uncooled
Laser Transmitter is manufactured in a 24-pin DIP assembly
with a single-mode fiber pigtail.
Description
The T92-Type 10 Gbits/s laser transmitters are
designed for use in transmission systems and high-
speed data communication applications. The trans-
mitter operates at the SONET OC-192 rate, as well
as, the ITU-T SDH rate of STM-64.
Features
■ Multisource compliant
■ Data rates to 10 Gbits/s
The transmitters meet all present Telcordia Technolo-
gies* GR-253-CORE requirements and the ITU-T
G.691 recommendations (see footnote 7, p.4). The
transmitters are also ideally suited for extended dis-
tance data and networking applications.
■ SONET and ITU-T compliant at OC-192 and
STM-64 (see footnote 7 on page 4)
■ Uncooled, field-proven InGaAsP MQW laser
■ 1300 nm DFB
Manufactured in a 24-pin DIP assembly, the transmit-
ter uses an hermetic MQW isolated 1300 nm DFB
laser, an InGaAs PIN photodiode back-facet monitor
and a GaAs laser driver IC. The transmitter requires
a single power supply (–5.2 V or +5.0 V). Clocked
operation can be enabled for those applications
where jitter is critical.
■ Clocked or nonclocked operation with single-ended
or differential inputs
■ 50 Ω ac-coupled 500 mVp-p—1000 mVp-p single-
ended data and clock inputs
■ Operation from single –5.2 V or +5.0 V power sup-
ply
Pin information is listed in Table 1.
■ Low profile, 24-pin PWB assembly
■ Automatic optical power control
■ Wide operating case temperature range: 0 °C to
70 °C
