TRXAG1VXIEMS

TRXAG1VXIxMS Very Long Haul Gigabit Ethernet SFP Transceivers with Digital Diagnostics Features Compatible with SFP MSA Pb Lead Free Design & Fully RoHS Compliant Digital Diagnostics through Serial Interface Internal Calibration for Digital Diagnostics APD Receiver Up to 120km with Single Mode Fiber Loss of Signal Output & Tx Disable Input Hot-pluggable Eye Safe (Class I Laser Safety) Duplex LC Optical Interface Single +3.3V Power Supply Description The TRXAG1VXIxMS SFP fiber optic transceivers with integrated digital diagnostics monitoring functionality offer a quick and reliable interface for Gigabit Ethernet 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 transceivers use a high power 1550nm DFB laser and an ultra high sensitivity Avalanche Photodiode (APD) receiver to provide a minimum optical link power budget of 32dB, corresponding to a transmission distance of around 120km of single mode fiber (assuming a total connector and splice loss of 2dB, total system penalty of 3dB and fiber loss of 0.22dB/km). The transceivers satisfy Class I Laser Safety requirements in accordance with the U.S. FDA/CDRH and international IEC-60825 standards. The TRXAG1VXIxMS 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 colored bail-type latches, which offer an easy and convenient way to release the modules. The latch is compliant with the SFP MSA. The transmitter and receiver DATA interfaces are ACcoupled 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 -5°C to +85°C (“E” option). The housing is made of metal to enhance EMI protection. Absolute Maximum Ratings Parameter Storage Temperature Operating Case Temperature1 Supply Voltage Maximum Input Optical Power (30 seconds max.)
