The BTR-7940G 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 and ITU-T 983.3 application. 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.

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.
