DESCRIPTION

The BTRS-9720G series is high performance module for

single fiber communications by using 1550 nm transmitter

and 1310 nm receiver. The transmitter section uses a

multiple quantum well 1550 nm DFB laser and is a class 1

laser compliant according to International Safety Standard

IEC 60825. The receiver section uses an integrated 1310 nm

detector preamplifier (IDP) mounted in an optical header

and a limiting post-amplifier IC. A PECL logic interface

simplifies interface to external circuitry. LV-TTL Signal

Detect is used.

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.
