DESCRIPTION
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.
LASER SAFETY
This single mode transceiver is a Class 1 laser product. It
complies with IEC-60825 and FDA 21 CFR 1040.10 and
1040.11. The transceiver must be operated within the
specified temperature and voltage limits. The optical ports
of the module shall be terminated with an optical connector
or with a dust plug.
