FEATURES
DESCRIPTION
l Bi-Directional Single-Fiber Transceiver
l Compliant with IEEE 802.3ah 1000BASE-BX10
l 1490 nm DFB LD Transmitter
l 1310 nm Receiver
The BTRS-7910CG 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 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
1000BASE-BX and ITU-T 983.3 application. A PECL logic
interface simplifies interface to external circuitry. LVTTL
signal Detect is used.
l Link distance up to 10 km
l Single +3.3 V Power Supply
l RoHS Compliant
l 0 to 70oC Operating: BTRS-7910CG
l -20 to 85oC Operating: BTRS-7910ACG
l LVPECL Differential Inputs and Outputs
l LVTTL Signal Detect Output
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
l SONET/SDH Equipment Interconnect
l Fiber Channel Links
