FEATURES
DESCRIPTION
l Single Fiber Bi-Directional Transceiver
l 1510 nm DFB LD Transmitter
l 1590 nm Receiver
The BTRS-77120C-1510G series is high performance
module for single fiber communications by using 1510 nm
transmitter and 1590 nm receiver. A guaranteed minimum
optical link budget of 31 dB is offered which can correspond
to a link distance of over 120 km (assuming worst case fiber
l 31 dB Power Budget at Least
l Distance Up to 120 km
l 0 to 70oC Operating
loss of 0.22 dB/km). The transmitter section uses a
l Speed up to 1300 Mbps
multiple quantum well 1510 nm DFB laser and is a class 1
laser compliant according to International Safety Standard
IEC 60825. The receiver section uses an integrated 1590 nm
detector preamplifier (IDP) mounted in an optical header
and a limiting post-amplifier IC. A PECL logic interface
simplifies interface to external circuitry. Signal Detect with
LC-TTL is used.
