Civcom’s Compact Transponder is a Long Reach and Extended Long Reach Widely Tunable Transponder designed for DWDM applications. The transponder contains both a 10Gbps widely tunable transmitter and a wide band receiver. Civcom’s Compact Transponder interface is compatible with the 300PIN MSA and I2C interface. The compact transponder uses a Negative chirp Mach Zehnder Lithium Niobate modulator to enable operation across the entire C-band and over long distances. Integrated Mux & Demux are used to convert parallel electrical signals into serial signals and serial signals into parallel electrical signals respectively. The electrical interface of both transmit and receive is based on 16 differential LVDS data lines and 6xxMbps clock. The module complies with OIF SFI-4 standard. A sensitive APD receiver converts optical to electrical signal and feeds the clock and data recovery (CDR) circuit. 50GHz ITU grid wavelength spacing is available as well as multi data rates of 9.95 to 12.5Gbps. Tuning the transponder’s laser is made possible through standard I2C commands. Civcom’s Compact Transponder allows the user to adjust the decision threshold of the receiver circuitry. The decision threshold can be set using I2C commands in the range of 10% to 90%.
