TRPA03MM

OC-3/STM-1 SFP Multimode Transceivers with Digital Diagnostics TRPA03MM Product Description The TRPA03MM SFP fiber optic transceivers with integrated digital diagnostics monitoring functionality provide a quick and reliable interface for OC-3/STM-1 multimode applications. The diagnostic monitoring functions, alarm and warning features are provided via an I2C serial interface. The transceivers are designed to be compatible with the ATM requirements at OC-3/STM-1 (156Mb/s) data rate. The TRPA03MM 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 transmitter design incorporates a highly reliable 1310nm LED and an integrated 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 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 enhancement.
