| Optoway BTR-3721G FEATURES l l l l l l l l l l l BTR-3721G *********************************************************************************************************************************************************************** (RoHS Compliant) DESCRIPTION 1550 nm TX / 1310 nm RX , 3.3V / 125 Mbps Single-Fiber Transceiver ********************************************************************************************************************************************************************** Single Fiber Bi-Directional Transceiver 1550 nm LD Transmitter 1310 nm Receiver Distance Up to 20 km Industry Standard 1 x 9 Footprint Single +3.3 V Power Supply PECL Differential Inputs and Outputs 0 to 70oC Operating Temperature RoHS Compliant Wave Solderable and Aqueous Washable Class 1 Laser International Safety Standard IEC-60825 Compliant The BTR-3721G 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 laser and is a class 1 laser compliant according to International Safety Standard IEC-60825. The receiver section uses an integrated 1550 nm detector preamplifier (IDP) mounted in an optical header and a limiting post-amplifier IC. A PECL logic interface simplifies interface to external circuitry. 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.

The power supply filtering is required for good EMI performance. Use short tracks from the inductor L1/L2 to the module Rx Vcc and Tx Vcc. A GND plane under the module is required for good EMI and sensitivity performance. *********************************************************************************************************************************************************************** OPTOWAY TECHNOLOGY INC.
