Optoway BTR-7940G 1 *********************************************************************************************************************************************************************** BTR-7940G / BTR-7940-SPG 1490 nm TX / 1310 nm RX , 3.3V / 1.25 Gb/s RoHS Compliant Single-Fiber Transceiver ********************************************************************************************************************************************************************** FEATURES DESCRIPTION l l l l l l l l l l l l l l The BTR-7940G 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 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.
