OTU Transponder

Optical Transponder VS Muxponder

In optical transmission, both transponder and muxponder belong to OTU(optical transform unit)/wavelength conversion unit, the main function is to converge or convert one or multiple client-side signals after access, and output DWDM(according to ITU-T G.694.1 recommendation) or CWDM(according to ITU-T G.694.2 recommendation) standard wavelength, in order to facilitate the multiplexing unit can perform WDM on optical signals of different wavelengths.

What is Transponder?

Transponders are used to enable point-to-point connections over long distances when the client rate matches the optical wavelength. In cases where the client rates are lower than the optical wavelength.

What is Muxponder?

A muxponder is the element that sends and receives the optical signal on a fiber in much the same way as a transponder except that the muxponder has the additional functionality of multiplexing multiple sub-rate client interfaces onto the line interface.

Main difference between Transponder vs Muxponder

• Transponder

N  in  N  out: N* Low-speed client-side services==> N* Standard wavelength optical signals

                                                          4* 10G services ↔ 4* 10G services

• Muxponder

N  in One out: N* Low-speed client-side services ==> 1* High-speed standard wavelength optical signal

                                                           10* 10G any services ↔ 1* 100G

Optical Transponder (O-E-O) Application in WDM Network

OEO (Optical Electrical Optical) means optical→Electrical→optical. The optical signal to be amplified is first converted into an electrical signal, after 3R function (signal amplification, clock extraction, signal regeneration) and then converted into an optical signal, thereby playing a role in optical power amplification. It is mainly used to amplify a single signal at a low rate of 10Gbit/s or below one by one.

• Amplify the optical signal

If the input is a weak optical signal, the output can be converted into a strong optical signal.

• Multi-mode fiber to Single-mode fiber

If it is a multi-mode fiber, it can be converted into a single-mode fiber.

• Single-core fiber to Dual-core fiber

If it is a single-core fiber, it can be converted into a dual-core fiber.

• Optical wavelength conversion

If it is a white optical signal, it can be converted into a color optical signal.

• Electrical interface to Optical signal

If one side is equipped with an electrical interface module and the other side is equipped with an optical interface module, the RJ45 electrical interface signal can also be converted into an optical signal.

Features:

• Supports 155Mbit/s~100 Gbit/s working rate optional [depending on the OEO unit board and the OTM(Optical Transport Module) configured].

• Supports the full range of 1260~1650nm working wavelength (depending on the OTM(Optical Transport Module) configured).

• Multiple types of services are available, such as Ethernet, SDH, ATM, etc., and transparent transmission of access services.

• Application scenarios support single fiber to dual fiber, wavelength conversion, mode conversion, optical signal shaping and optical power amplification.

• Signal relay can be realized and the transmission distance can be extended (the distance depends on the OTM(Optical Transport Module) configured)
