DESCRIPTION

The BTR-7820G 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

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 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.
