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 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. Single Fiber SFF Bi-Directional Transceiver 1550 nm Transmitter 1310 nm Receiver Distance Up to 20 km Single +3.3 V Power Supply RoHS Compliant PECL Differential Inputs and Outputs 0 to 70oC Operating Temperature: BTRS-3720G -20 to 85oC Operating Temperature: BTRS-3720AG Wave Solderable and Aqueous Washable Class 1 Laser International Safety Standard IEC-60825 Compliant APPLICATIONS l WDM 155 Mb/s Links l SONET/SDH Equipment Interconnect l Fast Ethernet 100 Mb/s 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.
