FEATURES
DESCRIPTION
l Single Fiber Bi-Directional Transceiver
l 1550 nm DFB LD Transmitter
l 1310 nm Receiver
The BTRS-7720CG 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 1550 nm DFB 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. LV-TTL
Signal Detect is used.
l 14 dB Link Power Budget At Least
l Distance Up to 20 km
l Single +3.3 V Power Supply
l RoHS Compliant
l 0 to 70oC Operating: BTRS-7720CG
l -20 to 85oC Operating: BTRS-7720ACG
l Speed up to 1300 Mbps
l LVTTL Signal Detect Output
l PECL Differential Inputs and Outputs
l Wave Solderable and Aqueous Washable
l Class 1 Laser International Safety Standard IEC-60825
Compliant
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.
APPLICATIONS
l WDM Gigabit Ethernet Links
