Description
The C48-type 2.5 Gbits/s cooled laser transmitters
are designed for use in transmission systems and
high-speed data communication applications. The
transmitter operates at the SONET OC-48 rate, as
well as the ITU-T SDH rate of STM-16. The device
supports two wavelengths. The second wavelength
is selectable via pin 10.
The transmitters meet all present

GR-253-CORE requirements and the ITU-T
G.957 and G.958 recommendations. They are also
ideally suited for extended-distance data and net-
working applications.
Manufactured in a 24-pin DIP, the transmitter incor-
porates a hermetic multiquantum well (MQW) iso-
lated 1550 nm digital distributed feedback (DFB)
laser (D2526 versions), an InGaAs PIN photodiode
back-facet monitor, and a GaAs laser driver IC. The
unit uses two power supplies. The laser transmitter
requires 5 V, and the thermoelectric cooler (TEC)
requires 3.3 V. The clock may be enabled for those
applications where jitter is critical.
Pin information is listed in Table 1.
