FEATURES
DESCRIPTION
l Bi-Directional Single-Fiber Transceiver
l Compliant with IEEE 802.3ah-2004 1000BASE
l 1310 nm LD Transmitter
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-TRXTM 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 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.
