FEATURES
DESCRIPTION
l Single Fiber Bi-Directional Transceiver
l 1590 nm DFB LD Transmitter
l 1510 nm Receiver
The BTR-77120-1590G series is high performance module
for single fiber communications by using 1590 nm DFB LD
transmitter and 1510 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 loss of 0.22 dB/km). The transmitter
section uses a multiple quantum well laser and is a class 1
laser compliant according to International Safety Standard
IEC-60825. The receiver section uses an integrated 1510
nm detector preamplifier (IDP) mounted in an optical
header and a limiting post-amplifier IC. A PECL logic
interface simplifies interface to external circuitry.
