| Optoway BTRS-7940CG / BTRS-7940C-SPG FEATURES l l l l l l l l l l l l l l BTRS-7940CG 1 *********************************************************************************************************************************************************************** 1490 nm TX/ 1310 nm RX , 3.3V / 1250 Mbps RoHS Compliant Single-Fiber Transceiver *********************************************************************************************************************************************************************** DESCRIPTION Bi-Directional Single-Fiber Transceiver Compliant with IEEE 802.3ah 1000BASE-BX 1490 nm DFB LD Transmitter 1310 nm Receiver 20 dB Power Budget At Least Link distance up to 40 km Industry Standard 1 x 9 Footprint Single +3.3 V Power Supply RoHS Compliant 0 to 70oC Operating LVPECL Differential Inputs and Outputs LVTTL Signal Detect Output Wave Solderable and Aqueous Washable Class 1 Laser International Safety Standard IEC-60825 Compliant 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. LASER SAFETY This single mode transceiver is a Class 1 laser product. It complies with IEC-60825 and FDA 21 CFR 1040.10 and 1040.11. The transceiver must be operated within the specified temperature and voltage limits. The optical ports of the module shall be terminated with an optical connector or with a dust plug.
