Wave Solderable and Aqueous Washable
Class 1 Laser International Safety Standard IEC-60825
Compliant
The BTR-5720G series is high performance module for
single fiber communications by using 1550 nm DFB LD
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 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.
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.

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.
