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.
Features
Lead Free Design & Fully RoHS Compliant
Compliant with IEEE 802.3ah/D3.3 (100BASE-LX10)
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.
Compatible with SFP MSA
Digital Diagnostics through Serial Interface
Internal Calibration for Digital Diagnostics
1310nm Fabry Perot Laser Transmitter
Distances up to 10km
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.
