Civcom’s Small Form Factor Transponder is a 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 10G-SFF interface is compatible with the 300PIN MSA and I²C interface. The Small Form Factor Transponder uses a widely tunable laser covering the entire C-Band.

The 10G-SFF uses a Negative chirp Mach Zehnder Lithium Niobate modulator to enable High performance under OSNR load across the entire C-Band and over long distances.

Integrated SERDES is 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 bit rates including 9.95Gbps, 10.3Gbps, 10.5Gbps, 10.7Gbps, 11.1Gbps and 11.35Gbps. Tuning the transponder’s laser is made possible through standard I²C commands.

Civcom’s Small Form Factor allows the user to adjust the decision threshold of the receiver circuitry. A decision threshold in the range of 10% to 90% can be set using I²C commands or external hardware pin.
