With the increased network requirements of individuals and enterprises, carriers are faced with unique challenge. That is, how to leverage existing and new optical networks so as to accommodate current growth and prepare for future expansion in the most effective manner? Muxponder technology, as a part of WDM technology, can maximize the fiber capacity to the extreme and meet the demands. It aggregates multiple services into a single wavelength which are then multiplexed along with other wavelengths into the same fiber.
100G Multiprotocol Multirate Muxponder Basic
The 100G multiprotocol multirate muxponder is optimized for high-capacity optical transport networks (OTN) migrating to 100G and data center or enterprise networks with significant investment in 10G and 40G router ports. It has two 40G QSFP+, ten 10G SFP+ client interfaces and a 100G CFP line interface that can cost-effectively support pluggable short range, DWDM metro and long range coherent 100G optics. Also, the 100G muxponder supports a wide variety of client services and protocols including 40G LAN, 10G LAN/WAN, STM64/OC-192, and 8G/10G Fibre Channel. Moreover, it supports an arbitrary mix of 10Gbps and 40Gbps client interfaces, up to a total of 100 Gbps.
Three Working Modes of 100G Multiprotocol Multirate Muxponder
As stated above, the 100G muxponder offers remarkable flexibility with fully pluggable interfaces, which can host 2x40G QSFP+ and 10x10G SFP+. So for customers with a large number of 10G services in their network, the 100G muxponder is an efficient way to combine ten 10G services into a single 100G service on the line side. For customers with a mix of 40G and 10G services, the 100G muxponder can flexibly carry any mix of services without the need to pre-plan the network or replace hardware for different mixes. Here shows the three different user-configurable muxponder options:
10 x 10G client services into 100G DWDM uplink
three different working modes of 100G multiprotocol multirate muxponder
In muxponder 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 one single wavelength. With this aggregation method, the muxponder thus maximizes the fiber utilization and presents effective low cost, easy to operate solutions for today’s enterprises and carriers.
Designed with plug-in card type, fiber-mart.com 100G multiprotocol multirate muxponder can be used as one part of our FMT transport system along with other plug-in cards like VOA, DCM, EDFA, etc. But the muxponder occupies two slots while the other plug-in cards occupy one slot.
The 100G multiprotocol multirate muxponder can be used with OEO transponders when building WDM network, or with an embedded WDM signal on the same system. The number of line signals has to be less than, or equal to the number of ports on the WDM multiplexer. Typically, the OEO transponders and muxponders are favored over an embedded WDM transceiver if a switch vendor doesn’t support WDM transceivers. Or if a carrier needs to present a client signal to its users instead of a WDM signal.
Recommendation: Data center optimized OEO transponders and muxponders are the first choice for connecting geographically dispersed data centers over distance, since they are low in latency and high in MTBF (Mean Time Between Failures). This is especially true for Fibre Channel and other latency sensitive protocols. But if you have to use a Telco’s network, or if you need to have a full standard conform network interface like SDH (Synchronous Digital Hierarchy), SONET or OTH (Over The Horizon), you should use a ISP compliant WDM design. Please keep in mind that this could limit the features and capabilities of your Fibre Channel network.
In addition, the 100G-CFP based 100G aggregated interface allows 100G muxponder to cover a wide variety of applications ranging from multiprotocol aggregation over a dedicated fiber using 100GBASE-LR4 or 100GBASE-ER4 CFPs to complex DWDM networks employing metro or coherent CFP pluggable transceivers. By designing the 100G interface around standard CFP optics, the 100G Muxponder can take advantage of technical innovations in the rapidly changing 100G optics market. Rather than forcing network operators to make a 100G optics decision today that will be expensive to change, 100G pluggable optics give network operators the ability to adapt with changing technology.
Conclusion
With the flexible client architecture, the 100G multiprotocol multirate muxponder enables a seamless migration path from 10G up to 100G without hardware exchange. Besides, the exceptionally low power consumption allows the 100G muxponder to meet market demands for rack space savings and efficient power consumption, resulting in lowered total cost of ownership. So using the 100G muxponder to build more cost-effective WDM network would be a smart choice.
