Optoway BTRS-7760CG 1 *********************************************************************************************************************************************************************** BTRS-7760CG / BTRS-7760C-SPG / BTRS-7760ACG / BTRS-7760AC-SPG 1550 nm TX / 1310 nm RX , 3.3V / 1250 Mbps RoHS Compliant Single-Fiber Transceiver ********************************************************************************************************************************************************************** FEATURES DESCRIPTION l l l l l l l l l l l l l The BTRS-7760CG series is high performance module for single fiber communications by using 1550 nm transmitter and 1310 nm receiver. The transmitter section uses a multiple quantum well 1550 nm DFB laser and is a class 1 laser compliant according to International Safety Standard IEC-60825. 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. LV-TTL Signal Detect is used. Single Fiber Bi-Directional Transceiver Speed up to 1300 Mbps 1550 nm DFB LD Transmitter 1310 nm Receiver Distance Up to 60 km Single +3.3 V Power Supply RoHS Compliant LVTTL Signal Detect Output PECL Differential Inputs and Outputs 0 to 70oC Operating: BTRS-7760CG -20 to 85oC Operating: BTRS-7760ACG Wave Solderable and Aqueous Washable Class 1 Laser International Safety Standard IEC-60825 Compliant APPLICATIONS l WDM Gigabit Ethernet Links l SONET/SDH Equipment Interconnect l Fiber Channel Links 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.
