Fast Ethernet 100BASE-LX10 SFP
Transceivers with Digital Diagnostics
TRXAFEEX/ZX
Product Description
The TRXAFEEX/ZX SFP fiber optic transceivers provide a quick and reliable
interface for 100BASE-LX10 Fast Ethernet single mode applications. The
transceivers are compliant with IEEE802.3ah/D3.3 standard. The diagnos-
tic 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 require-
ments 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 transceivers have bail-type
latches, which offer an easy and convenient 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 operat-
ing case temperature range of -5°Cto +70°C (“B” option) or -40°C to +85°C
(“A” option). The housing is made of plastic and metal for EMI immunity.
