In 2006, the IEEE 802.3 working group formed the Higher Speed Study Group (HSSG) and found that the growth in bandwidth for network aggregation applications was outpacing the capabilities of networks employing link aggregation with 10 Gigabit Ethernet. (The standard was announced in July 2007 and was ratified on June 17, 2010).
In May 2011, it is important to note that 10GbE is still migrating into the data centers. The 10GbE movement into the data centers will continue; however, "future-proofing" is expected to proceed with an accent (40/100G), especially in regards to network productivity as well as operating expenses (OPEX costs).
North America MPO Connector Market Forecast The capability to choose increased speed will enable networks to play with the 10GbE resources to the access layer allowing 40/100GbE to handle traffic at the aggregation and core layers. In EXCUTIVE STUDY SERVICE, ElectroniCast Consultants provides our 2010-2015 of MPO fiber optic connectors used in 40/100GbE; specifically, providing a detailed quantitative market forecast of the consumption in North America, covering the following:
Cabling Alternatives 40GbE and 100GbE Cabling for 40GbE and 100GbE can be optical fiber or copper. The supportable channel length depends on the cable and the transceiver type. With regards to connectors, the only significant change outlined in the 802.3ba standard is the use of MPO (Multi-Fiber Push On) type connectors at the multimode transceivers to support the multi-fiber parallel optics channels. For data center environments operating at 40GbE or 100GbE, OM3 and OM4 multimode cabling is generally recommended because its reach supports a wider range of deployment configurations compared to copper solutions, and the cost is lower compared to single-mode solutions. Cabling alternatives 40GbE and 100GbE include the following:
MPO/MTP Connectors The 802.3ab standard requires multiple lanes of traffic per channel. To accomplish this, the 40/100GbE standard uses parallel optics. The 40GbE specification calls for a 12-fiber cabling solution with each channel featuring four dedicated transmit fibers and four dedicated receive fibers. The middle four fibers remain unused, or dark.
The 100GbE solution specifies 24 fibers divided into two 12-fiber arrays with one array dedicated to transmit and the other dedicated to receive. In each array, the middle ten fibers are dedicated to traffic while the two fibers on either end remain dark. For 100GbE several interface variants have been described with the preferred option being a single 24-fiber MPO/MTP connector. Alternately, two 12-fiber connectors can be positioned either vertically or side by side to make up the channel.
MPO is the industry acronym for "multi-fiber push on." The MPO-style connectors are most commonly defined by two different documents:
The MTP connector is a high performance MPO connector with multiple engineered product enhancements to improve optical and mechanical performance when compared to generic MPO connectors. The MTP connector is in complete compliance with all MPO connector standards including the EIA/TIA-604-5 FOCIS 5 and the IEC-61754-7. The MTP connector is inter-matable with all generic MPO-style connectors that are compliant to these industry standards. For the purpose of this ElectroniCast market forecast, the MPO and the MTP are grouped together.
According to ElectroniCast, 12-fiber multimode MPO connectors dominates the North American (Mexico, Canada and the United States) 40/100GbE MPO connector marketplace, based on consumption value.
