In optical networks, muxponder technology is used to aggregate multiple services into a single wavelength/uplink using OTN mapping.

Muxponder technology utilizes ITU OTN (Optical Transport Network) protocol and mapping to reduce the number of wavelengths needed to transport the data, making it the preferred choice for maximizing fiber capacity and simple future network growth.
Muxponder technology aggregates multiple services such as Ethernet, SONET/SDH, Fibre Channel, HD/SD-SDI, OTU2/3/4, etc. into a single 10G/100G/200G/400G wavelength/uplink. This reduces the number of wavelengths needed for the solution, and increases spectral efficiency of the network.
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
The muxponder is often used in optical transport solutions provided to carriers, dark fiber providers and ISPs 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.
10G Muxponder
The ITU G.709 standards-based 10G OTU2 muxponder aggregates up to 16 services of up to 4G into a single uplink trunk. The typical rates and protocols supported include: Fast Ethernet, GbE, 1G/2G/4G FC/FICON, STM-1/OC-3, STM-4/OC-12, STM-16/OC-48, SD-SDI, HD-SDI, 3G –SDI and DVB-ASI (see Figure 1).
100G Muxponder
Using ITU G.709 standards-based OTU4 uplink to aggregate different protocols (Ethernet, Fibre Channel, SDH/SONET, and OTN) simultaneously, the 100G muxponders provide the perfect access platform for the needs of multiple clients and enables merger of legacy and new services transparently over the same optical transport layer (see Figure 2).
The 100G muxponder aggregates services between 8G and 40G. The typical rates and protocols supported include: 10GbE, 40GbE, 8G/10G/16G/32G Fibre Channel, STM-64/OC-192, OTU2/OTU2e, and OTU3/OTU3e.
200G Muxponder
Using OTN OTUC2 uplink to aggregate a mix of Ethernet, Fibre Channel, SDH/SONET, and OTN protocols, enables the 200G muxponders to provide the perfect access platform for the needs of different clients and enables the merger of legacy and new services transparently over the same optical transport layer (see Figure 3).
The 200G muxponder aggregates services between 8G and 100G. The typical rates and protocols supported include: 10GbE, 40GbE, 100GbE, 8G/16G/32G FC, STM-64/OC-192, OTU2/OTU2e, OTU3, and OTU4.
400G Muxponder
The ITU G.709 standards-based OTUC4 uplink aggregates a mix of Ethernet, Fibre Channel, and OTN protocols, and enables the 400G muxponders to provide the perfect access platform for building a multi-rate and multi-service high capacity optical transport layer (see Figure 4).
The 400G muxponder aggregates services between 10G and 100G. The typical rates and protocols supported include: 10GbE, 25GbE, 100GbE, 16G/32G FC, OTU2/2e, and OTU4.
Benefits of OTN Muxponders
- Reduction of the number of wavelengths needed in the optical network
- Every port can be used for multiple types of services, reducing management cost and CAPEX of the optical transport network
- OTN provide extensive monitoring information, this improve the maintenance of the optical network (OPEX)
- Unify legacy and next generation protocols and services over a common optical layer
- Cost reduction of the optical solution by:
- Reducing the number of colored optics by a factor of 8-24
- Reducing the number of WDM filters and patch cords / patch panels needed
- Reducing cost of amplification as there are less wavelengths to amplify
- Lower power consumption and reduction of the rack space needed for the optical solution
- Higher spectral efficiency, leveraging existing infrastructure for serving additional clients
- Layer-1 encryption per service or per uplink for secure data transport
- Cost-effective alien wavelength over existing WDM or OTN infrastructure
