What's Muxponder Technology


Muxponder technology diagramIn today’s optical networks, WDM technology (Wavelength Division Multiplexing) is commonly used. With WDM solution, each service whether a GbE, 10G LAN, SONET/SDH,Fibre Channel or HD/SD-SDI, is assigned an independent dedicated wavelength which then are multiplexed into one single fiber rather than using multiple fibers. WDM technology allows single fiber optic cable to be used for transport of multiple services while assigning to each dedicated spectral wavelength, thus increasing fiber capacity. However, to even further maximize the fiber capacity, muxponder technology is often preferred.

Muxponder technology, as a part of WDM technology, aggregates multiple services into a single wavelength which are then multiplexed along with other wavelengths into the same fiber.  In this model, all 10G or sub-10G services are first aggregated into a single 100G or 10G uplink respectively and then passing between the sites utilizing only single wavelength. Therefore, instead of each service having dedicated wavelength, with PacketLight’s muxponder, there can be as many as 16 different services that share the same wavelength. With this aggregation method,the muxponder technology maximizes the fiber utilization and presents effective low cost, easy to operate solutions for today’s enterprises and carriers.

PacketLight’s advanced next generation muxponder technology provide efficient and flexible aggregation layer of multi-protocol/multirate into single uplink trunk.

There are two main flavors of Muxponders:

1) 10G OTU2 Muxponder aggregating up to 16 sub-10G services into single uplink trunk. The typical rates and protocols supported range from Fast Ethernet ,GbE, 1/2/4/8G FC/FICON, STM-1/OC-3, STM-4/OC-12, STM-16/OC-48, SD-SDI, HD-SDI, 3G –SDI and DVB-ASI and others.

2) 100G OTU4 Muxponder aggregating 10x10G and 2x40G services into single trunk. The typical rates and protocols supported range from 10G LAN 8G/10G FC , STM-64/OC-192, OTU2, OTU2e, 40 Gigabit Ethernet (40GBase-SR4, 40GBaseLR4), OTU3, OTU3e, 100 Gigabit Ethernet (100GBase-SR10, 100GBase-LR10, 100GBase-LR4, 100GBaseER4)

Using standard based OTU4 and OTU2 OTN layer uplinks to aggregate simultaneously SDH/SONET, Ethernet, Fibre channel and Video services, muxponders provide a perfect access platform for multiple clients’ needs and allow merger of legacy and new services transparently over the same optical transport layer.

The muxponder solution is often integrated as part of solutions for carriers, dark fiber providers and ISP’s due to its carrier grade features such as remote monitoring and management, link diagnostic tools and bi-directional performance monitoring of the client service interfaces and uplink.
Next generation muxponder’s main benefits are:

  • Significantly reduces the number of wavelengths needed for the optical transport solution
  • Simplifies the optical transport network management and maintenance complexity
  • Unifies legacy and next generation protocols and services over common optical layer
  • Reduces the optical solution cost significantly by:

       o Reducing the number of colored 1/2.5/4G/10G optics by a factor of 8-10
       o Reducing the number of WDM filters and patch cords/patch panel needed
       o Reducing the optical amplification requirement
  • Lowers the power consumption and reduces the rack space needed for the optical solution
  • Provides higher spectral efficiency leveraging existing infrastructure for serving additional clients
  • Cost effective Alien wavelength over existing WDM or OTN infrastructure
