What are Muxponders?

In optical networks, muxponders are used for flexible and efficient aggregation of multiple client services into a single wavelength/uplink using OTN mapping.

How do muxponders aggregate different services into one uplink?

Muxponders utilize ITU-standard OTN (Optical Transport Network) protocol to map a mix of services onto the OTN layer. This reduces the number of wavelengths needed to transport data, by aggregating data, storage, video and voice services (Ethernet, SONET/SDH, Fibre Channel, and SD/HD/3G–SDI) into a 100G/200G/400G wavelength/uplink. This reduces the number of wavelengths needed, and increases spectral efficiency of the network.

What are the advantages of muxponders?

  • Aggregates a number of different services into one wavelength removing the need for costly WDM optics.
  • Simplifies network management, as there are fewer wavelengths to manage.
  • Saves operational costs (OPEX) thanks to low power consumption and small footprint.
  • Enables manage a mix of protocols over the same wavelength at the OTN level (as opposed to performance monitoring of each of the protocols).

What uplinks do PacketLight muxponders support?

PacketLight supports different types of muxponders:

  • 10G muxponder – aggregates services between 100Mbps and 4G into a 10G OTU2 uplink
  • 100G muxponder – aggregates services between 8G and 40G into a 100G OTU4 uplink
  • 200G muxponder – aggregates services between 8G and 100G into a 200G OTUC2 uplink
  • 400G muxponder – aggregates services between 10G and 100G into a 400G OTUC4 uplink

Who uses muxponders?

Any enterprise building their own private fiber optic network, any service providers building or expanding their existing networks. Muxponders are a great solution for high-capacity networks with pay-as-you-grow architecture.  The carrier-grade features of muxponders make them a sought-after solution by carriers, ISPs, and dark fiber providers.
