Applications of 2.5G 1R SFP to SFP Transponder

Excellent Transponder Supporting Wavelength Conversion for WDM Networks

The optical transponder can convert 125M~2.5G Ethernet signals into a corresponding wavelength in CWDM and DWDM network infrastructures. It enables network operators to implement a wide range of media conversions in a compact and flexible design.

Optical Transponder for Fiber-Type Conversion and Optical Repeating

The optical transponder can be deployed in the seamless integration of different fiber types by converting multimode fiber to single-mode fiber, dual fiber to single fiber, and it can also be used as a repeater to convert the weak optical signals into the strong optical signal for continuous

Available for All-in-One Multi-Service Transport System

As a part of multi-service transport system, hot-swappable pluggable 2.5G 1R SFP to SFP Transponder Card only occupies 1 slot in the 2U chassis, and it allows the backbone of the network to be flexible and easier to be managed and maintained. Our transponders are available in two form factors, chassis-based slide-in cards and stand-alone converters, allowing you the most flexibility for your network. Our transponders also utilize both fixed optics and Small Form-Factor Pluggable (SFP) transceivers allowing you to customize each converter for the cable type you are using. View the different form factors as below:
