Fast Ethernet 100BASE-LX10 SFP Single
Mode Transceivers with Digital Diagnostics
TRXAFELX
Product Description
The TRXAFELX SFP series of fiber optic transceivers provide a quick and
reliable interface for 100BASE-LX10 Fast Ethernet single mode applica-
tions. The transceivers are compliant with IEEE802.3ah/D3.3 standard.
The diagnostic functions, alarm and warning features as described in
the Multi-Source Agreement (MSA) document, SFF-8472 (Rev. 9.4), are
provided via an I²C serial interface. All transceiver modules satisfy Class
I Laser Safety requirements in accordance with the U.S. FDA/CDRH and
international IEC-60825 standards.
The transceivers connect to standard 20-pad SFP connectors for hot plug
capability. This allows the system designer to make configuration chang-
es or maintenance by simply plugging in different types of transceivers
without removing the power supply from the host system.
The transceivers have bail-type latches, which offer an easy and conve-
nient way to release the modules. The latch is compliant with the SFP
MSA.
The transmitter incorporates a highly reliable 1310nm InGaAsP laser
and an integrated driver circuit. The receiver features a transimpedance
amplifier IC optimized for high sensitivity and wide dynamic range. The
transmitter and receiver DATA interfaces are AC-coupled internally. LV-
TTL Transmitter Disable control input and Loss of Signal (LOS) output in-
terfaces are also provided.
The transceivers operate from a single +3.3V power supply over three
operating case temperature ranges of -5°C to +70°C (“B” option), -5°C to
+85°C (“E” option), or -40°C to +85°C (“A” option). The housing is made of
plastic and metal for EMI immunity.
