The GIGAOPTO's GTS-C2712-80DC series single mode transceivers are small form factor pluggable modules for duplex optical data communications such as 1000BASE Gigabit Ethernet and 1x Fiber Channel long reach (LR) application. The 1000BASE SFP module provides 1.25Gb/s throughput up to 80km over single-mode fiber (SMF). It is available for all 18 CWDM channels from 1270nm to 1610nm wavelengths, which helps to increase the bandwidth of an existing fiber infrastructure without adding new fiber strands.


The CWDM SFP module has been integrated with an enhanced digital diagnostic monitoring interface (DDMI) per SFF-8472, which provides real-time monitoring of the transceiver temperature, laser bias current, optical power, received optical power and transceiver supply voltage.


The CWDM SFP series are designed to be compatible with SFP Multi-Source Agreement and SFF-8472 specifications.




As a global provider of Brand Compatible Networking products, we Gigaopto have made significant investments over the past few years to support our customers, as well as in our physical infrastructure and test equipment platforms. Our overall trusted engineering and testing capabilities allow us to produce a large selection of Brand Compatible Transceivers.
This (1.25G SFP CWDM 80km) is 100% compatible with mainstream optical devices. Below is a table of P/N correspondence for different brand modules(e.g.1270nm wavelength channel). For more information, please don't hesitate to contact us.
