TRXAFEEX

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 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 changes 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. LVTTL Transmitter Disable control input and Loss of Signal (LOS) output interfaces are also provided. The transceivers operate from a single +3.3V power supply over operating 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.
