Based on the world's first ONOS (Open Network Operating System) open architecture SDN IPRAN green business enterprises in Tianjin Unicom successful opening, which is an important outcome of China Unicom, Huawei and ONOS SDN open source community in the field of joint innovation.

According to CIR (CommunicationsIndustryResearchers) latest report, "2015 Active Optical Cable Market: data centers and high-performance computing market," in 2020 for the data center of the active optical cable (AOC) market will reach $ 4.2 billion.

According to a "software-defined networking market in North America, including solutions (SDN switches, SDN controllers, virtual cloud application), end-users (businesses, telecom service providers, cloud service providers)," the survey report, as of 2019, North American software-defined network (SDN) market will grow from $ 1,478,300,000 in 2014 increased to $ 4,604,400,000, compound annual growth rate (CAGR) to reach 25.5 percent.

Market research firm IHS Infonetics latest optical networking market research report, the global optical network market in the third quarter reached $ 2.95 billion, from the previous quarter fell 10% year on year over the same period fell 1.7%. Last quarter of the global optical network market has 21% of the chain growth.

Optical transmission equipment manufacturers Optelian recently launched MPX-9XXX series of two transmission platform for its 100Gbps new muxponder product.

Has been in the Internet industry, we all know that Facebook is developing its own software and hardware products, and they are trying to guide the development of this area, OCP open computing platform is an example. The company recently announced that it is independent of the development of next-generation data center with top of the rack TOR 100Gbps Ethernet switches.

Optical module types include 1 × 9, SFF, SFP, GBIC, XENPAK, XFP, SFP+ and 10G optical modules above.

Optical interface is connected to the fiber optic cable physical interface. Usually SC, ST, LC, FC and other types. For 10Base-F connections, usually ST type connectors, and the other end connected to the optical fiber FC step bobbin. FC (Ferrule Connector), to strengthen its external way is to use a metal sleeve, fastening means for the turnbuckle. ST interface is typically used for 10Base-F, SC interfaces typically used to 100Base-FX and GBIC, LC typically used for SFP.

Fiber optic connectors are plugs at both ends by an optical fiber and fiber composition, plug by locking pin and peripheral structures. Depending on the locking mechanism, fiber optic connectors can be divided into FC type, SC type, LC type, ST type and KTRJ type.

Gigabit optical interface can operate in two modes enforcement and auto-negotiation. 802.3 specification only supports gigabit optical port rate 1000M to support full-duplex and half-duplex duplex mode.
