Compliant
The BTR-7840G 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 1310 nm DFB 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 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.
