Compliant
The BTRS-37120-1510G series is high performance
module for single fiber communications by using 1510 nm
transmitter and 1590 nm receiver. The transmitter section
uses a 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.
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.
