Demand for 100Gbit/s (100G) network connections is growing rapidly. Initial deployments in the long-haul network and data center are now being eclipsed by the widespread deployment of 100G interfaces in the metro network. The latest core routers, metro Ethernet switches, long haul and metro DWDM systems and large data center switches support 100G interfaces. Many systems now have 200G or 400G backplane connection supporting up to four 100G interfaces now or a single 400G interface.
During 2012 we saw the introduction of second- and third-generation 100G solutions with cost-effective 10x10G optical modules and production-ready 4x25G optical modules for metro systems. In addition, Cisco has announced the proprietary CPAK optical module format. Long-haul 100G coherent receiver solutions with DP-QPSK modulation are shipping from multiple silicon and optical module vendors, as well as telecom equipment manufacturers. There are now almost 20 vendors with 100G physical layer devices (PHY) and more than twenty 100G optical module manufacturers covering for long-haul, metro/enterprise and data center applications.
Our survey goes beyond gauging the depth and breadth of use for 100G optical modules and PHY semiconductor components by providing insights into which devices telecom equipment manufacturers are using, for which applications and how they rate each vendor. The report includes information about the use of PHY devices, 100G optical modules and the most important features when system developers select these modules. The report also includes vendor rankings for PHY devices and 100G optical modules and information on plans for the use of 400G interfaces.
The 100G market is divided into three distinct areas: long haul, metro/enterprise and the data center. The industry has developed three distinct 100G technologies. Coherent receivers with DP-QPSK modulation have been adopted by the OIF for long-haul networks and are now the focus for all long-haul equipment and optical module manufacturers. Several are using DP-QPSK with coherent receivers for metro deployments. 100GBase-LR4 Ethernet will be the dominant technology for the metro and enterprise applications with 10GBase-ER4 used for longer links. The alternative 10x10 MSA solution, with 2km, 10km and 40km options, is used in many cost sensitive applications. In the data center, 10GBase-SR10 Ethernet and InfiniBand are the dominant 100G interconnects today. 100GBase-CR4 and 100GBase-SR4 with QSFP28 optical modules will reduce the future cost of 100G in the data center.
100G Components User Survey: 2014 Market Outlook analyzes the current and projected use of 100G optical modules and PHY semiconductor components by equipment vendors, based on the results of an exclusive worldwide survey of engineers, designers, product managers and sales/marketing personnel that work for telecom and networking system equipment manufacturers and suppliers. The responses to our survey make it clear that these devices are critical components in many types of networking equipment, from long-haul to the access edge, data center and core of the network.
