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.

Optical communication technology in the 2015 forum held recently, Ovum analyst Daryl Inniss speech, analyze the optical communication opportunities in the data center field. He said the data center network is driving demand for high-bandwidth connections between data centers and data center for internal. Terabit-level connection between the data center needs; and internal data centers require more cost connection to 100G. However, the high cost of optical networks market slowdown in the rate of expansion is a fundamental problem.

PTN Layer 2 technologies can be seen as a simplified version of the mechanism and OAM enhancements combination. In the realization of the technology, the two main technical PBT and T-MPLS will be a substitute for SDH, rather than the IP/MPLS competitors, similar to its network theory, are based on end to end, bidirectional point to point connection, and provides a central management, within 50 milliseconds protection switchover; either can be used to implement SONET/SDH to packet switching transition, in the protection of existing transmission resources, it can be similar to the existing SDH network functions to implement the network packet switched network transformation.

T-MPLS (Transport MPLS) is a connection-oriented packet transport technology. In the transport network, the client signal is mapped into the MPLS frame and use MPLS mechanisms (such as label switching, the label stack) forwards, while it increases the basic functions of the transport layer, such as connectivity and performance monitoring, survivability (protection and restoration), management and control plane (ASON/GMPLS).

Active optical network central office equipment (CE) and remote equipment (RE) connected via active optical transmission equipment. Transmission technology is the backbone network SDH and PDH technologies have been widely adopted, but the main SDH technology. Remote device mainly to complete the collection business, interface adapter, multiplexing and transmission. Central office equipment mainly to complete the interface adapter, multiplexing and transmission. In addition, the central office equipment to the network element management system also provides network management interface. In the actual construction of the access network, active optical network topology is typically star or ring. Active optical network technology has the following characteristics:

APON the mid-1990s developed, and was able to develop a fiber-based standard include IP data, video and Ethernet services for business and residential users, logical ATM and PON were selected as the network protocol and network platform, because ATM is seen as the only able to provide various types of communication protocols, and is the most economical broadband PON fiber solution.

It is well known in the optical communications optical module dominate, and photonic chip is the heart of the optical module is the core of the optical communication system. Photonic chip strength, represents a country, a company's optical communications technology. Therefore, when the industry proud, "Optical communication is a Chinese high-tech and advanced level in the gap in the world one of the smallest fields," when we need a critical analysis of this sentence.
