Description
F-tone Networks’FTCS-TD1X-80D tunable transceiver is an integrated fiber optic transceiver that provides a high-speed serial link at signaling rates from 9.95 Gb/s to 11.3 Gb/s. The module complies with the 10 Gigabit Enhanced Small Form Factor Pluggable （SFP+）multisource agreement-MSA（SFF-8431） and SFF-8432，SFF-8690，SFF-8472.

This is an Enhanced Small Form Factor Pluggable Tunable SFP28 transceivers designed for use in 25Gb/s links up to 15km of G.652 single mode fiber. They are compliant with SFF-8431, SFF-8432, SFF-8690, and support 25GbE and CPRI 10 over 15km fiber. Digital diagnostics functions are available via a 2-wire serial interface, as specified in SFF-8472.

The FT-BE-F240X Tunable SFP+ module is a high performance tunable pluggable transceiver for use in the C-band window. The module is intended for 40km reach service from 8.5Gb/s to 11.09Gb/s high-speed telecommunications equipment where low-cost, extraordinary performance and reliability are essential.
