TRPAFESM

Fast Ethernet SFP Single Mode Transceivers with Digital Diagnostics TRPAFESM Product Description The TRPAFESM SFP series of fiber optic transceivers with integrated digital diagnostics monitoring functionality provide a quick and reliable interface for 100BASE-FX Fast Ethernet single mode applications. 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. The transmitter optical output power is compliant with ANSI X3.184-1993 standard for FDDI SMF-PMD category I. All 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 host system. 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 design incorporates a highly reliable 1310nm InGaAsP laser and a driver circuit. The receiver features a transimpedance amplifier IC 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 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 (“B” option) or -40°C to +85°C (“A” option). The housing is made of plastic and metal for EMI immunity.
