FEATURES
DESCRIPTION
l Bi-Directional Single-Fiber Transceiver
l Compliant with IEEE 802.3ah 1000BASE-BX
l 1490 nm DFB LD Transmitter
l 1310 nm Receiver
The BTR-7920G series is high performance module for
single fiber communications by using 1490 nm transmitter
and 1310 nm receiver. 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 1310 nm and block
1490 nm signal. This feature is suitable for IEEE 802.3ah
1000BASE-BX and ITU-T 983.3 application. 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.
