The BTRS-7910CG 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. A PECL logic interface simplifies interface to external circuitry. LVTTL signal Detect is used.
