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.

RECOMMENDED CIRCUIT SCHEMATIC
The split-load terminations for ECL signals need to be located at the input of devices receiving those ECL signals. 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.
