Very Long Haul Multi-Rate Gigabit Ethernet SFP CWDM Transceivers with Digital Diagnostics

The TRPEG1KVX-G MR CWDM SFP series of multi-rate fiber optic transceivers with integrated digital diagnostics monitoring functionality provide a quick and reliable interface for 1000BASE-LX Gigabit Ethernet and 1.062GBd Fiber Channel applications. The transceivers are designed to support data rates ranging from 1.25Gb/s down to 125Mb/s. 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 DFB laser and an ultra high sensitivity Avalanche Photodiode (APD) receiver to provide a minimum optical link power budget of 32dB, corresponding to a minimum transmission distance of 120km of single mode fiber, assuming a total connector/splice/CWDM mux and demux loss of 4.6dB, allocated system penalty of 1dB and fiber loss of 0.22dB/km. There are eighteen (18) wavelengths available, from 1271nm to 1611nm. All transceivers are Class I Laser products per U.S. FDA/CDRH and international IEC-60825 standards.

The TRPEG1KVX-G MR CWDM multi-rate 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 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 (Commercial) or -5°C to +85°C (Extended). The housing is made of metal for EMI immunity.
