FEATURES
DESCRIPTION
l Bi-Directional Single-Fiber Transceiver
l Compliant with IEEE 802.3ah 1000BASE-BX
l 1310 nm DFB LD Transmitter
l 1490 nm Receiver
l 1550 nm Enhanced Band Block
l 20 dB Power Budget At Least
The BTRS-7840CG series is high performance module for
single fiber communications by using 1310 nm transmitter
and 1490 nm receiver. This module is equipped with
3W-TRX^TM OE device to reject 1.55 um high power
video signal. The transmitter section uses a multiple
quantum well 1310 nm DFB laser and is a class 1 laser
l Link distance up to 40 km
compliant according to International Safety Standard
l Industry Standard 1 x 9 Footprint
l Single +3.3 V Power Supply
IEC-60825. The receiver section is designed to receive 1490
nm and block 1550 nm signal. This feature is suitable for
l RoHS Compliant
l 0 to 70^oC Operating
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
IEEE 802.3ah 1000BASE-BX and ITU-T 983.3 application.
The receiver section uses an integrated 1490 nm detector
preamplifier (IDP) mounted in an optical header and a
limiting post-amplifier IC. A PECL logic interface
simplifies interface to external circuitry.
Compliant
LASER SAFETY
APPLICATIONS
l WDM Gigabit Ethernet Links
l SONET/SDH Equipment Interconnect
l Fiber Channel Links
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.
