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 BTRS-7940CG 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 1490 nm DFB 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.
A PECL logic interface simplifies interface to external
circuitry. LVTTL signal Detect is used.
