Description
The 1345-Type fiber-optic receiver is designed for
use in transmission systems or medium- to high-
speed data communication applications. Used in
intermediate- and long-reach applications, the
receiver operates at the SONET OC-3 or OC-12 data
rate as well as the ITU-T synchronous digital hierar-
chy (SDH) rate of STM-1 or STM-4, depending on
the receiver model chosen. The receiver meets all
present
Telcordia Technologies GR-253-CORE
requirements, the current ANSI T1X1.5 intraoffice
specifications, and the ITU-T G.957 and G.958 rec-
ommendations. Compact packaging, a high level of
integration, and a wide dynamic range make these
receivers ideal for data communications.
Manufactured in a 20-pin DIP, the receiver consists of
a planar InGaAs PIN photodetector, a silicon pream-
plifier, a silicon bipolar limiting amplifier that converts
the small signal to ECL levels, a timing recovery unit
to recover the clock, and a silicon bipolar decision cir-
cuit.
