Description
The TRXBG1EXM modules are single fiber, bi-directional
SFP transceivers that provide a quick and reliable interface
for 1000BASE-BX Gigabit Ethernet applications. Two types
of modules are available: 1310nm DFB laser-based
transceiver (BX-U), and 1550nm DFB laser-based
transceivers (BX-D). These transceivers are designed to
support data rates ranging from 1250Mb/s down to 125Mb/s
and are integrated with digital diagnostics monitoring, which
provides features to detect a problem before system
performance is impacted. The diagnostic functions, alarms
and warning features are provided via an I2C serial interface
as described per the Multi-Source Agreement (MSA)
document, SFF-8472 (Rev. 9.4).
All modules meet Class I Laser Safety requirements in
accordance with the U.S. and international standards as
described in the FDA/CDRH and IEC-60825 documents,
respectively. The TRXBG1EXM transceivers connect to
standard 20-pad SFP connectors for hot plug capability.
This allows the system designer to make configuration or
maintenance changes by simply plugging in different types
of transceivers without removing the power supply from
the host system.
The transceivers have color-coded latches that identify the
TX wavelength. The MSA compatible latch offers an easy
and convenient way to release the module.
The transmitter and receiver DATA interfaces are AC-
coupled internally. LV-TTL Transmitter Disable control
input and Loss of Signal output interfaces are also provided.
The transceivers operate from a single +3.3V power supply
over an operating case temperature range of -5°C to +70°C
or -40°C to +85°C. The package is made of metal.
