The BTRS-7820CG series is high performance module for
single fiber communications by using 1310 nm transmitter
and 1490 nm receiver.
This module is equipped with
3W-TRX
TM
OE device to reject 1.55 um high power
video signal.
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 is designed to receive 1490 nm and block
1550 nm signal. This feature is suitable for IEEE 802.3ah
1000BASE-BX and ITU-T 983.3 application. The receiver
section uses an integrated 1490 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.
