FEATURES
DESCRIPTION
lBi-Directional Single-Fiber Transceiver
l1490 nm DFB LD Transmitter
l1310 nm Receiver
The BTR-7920 series is high performance module for single
fiber communications by using 1490 nm transmitter and 1310
nm receiver. The transmitter section uses
a multiple

lLink distance up to 20 km
lIndustry Standard 1 x 9 Footprint
lSingle +3.3 V Power Supply
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 1550/1490
nm signal. This feature is suitable for IEEE 802.3ah 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.
