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:

Optical fiber is a transmission beam subtle and flexible media. Fiber optic cables consist of a bundle of optical fibers, referred to as fiber optic cable. Fiber optic cable for data transmission is the most effective one transmission medium, the advantages of its advantages similar to the optical fiber, mainly in the following areas:

Active optical access technology Application bandwidth demand, high security communication enterprises and institutions access. It can also be used in the feeder section and wiring section of the access network, and mixed with other access technologies based on the use of wireless or copper wires.

AON (Active Optical Network) is a signal during transmission, the transmission network from the central office equipment to the use of the photoelectric conversion devices, active optoelectronic devices and fiber optic transmission equipment and other active optical fiber between user allocation unit. Active optical device comprises a light source (laser), optical receivers, optical transceivers, optical amplifiers (fiber amplifiers and semiconductor optical amplifiers).

Optical Access Network refers to the optical fiber as the transmission medium of the network environment. Technically fiber access network can be divided into two categories: active optical network (AON) and passive optical network (PON). Active optical network can be divided into SDH and PDH's AON; passive optical network can be divided into narrowband and broadband PON.

QSFP is from a simple single-mode fiber SONET applications out into other multimode fiber applications, such as Gbps Ethernet, Fibre Channel, InfiniBand and so on. Many MSA members of the supply VCSEL chip, parallel VCSEL chips, pushing the QSFP technology in the field of multi-mode.

MT namely mechanical docking transmission, multi-core ferrule number (usually a 12-pin). Performance by an optical fiber connector alignment accuracy decisions, and alignment accuracy can continue after the connection is stable. Ultimately, the alignment accuracy is eccentricity and pitch as well as matching precision guide pins and optical fiber to decide. If in the production process can reduce the deviation of the guide pin and molding process, any one MPO connector performance can be improved.

40Gbit/s CFP optical module is hot-pluggable optical modules clients, including 40Gbit/s BASE-LR4 1310nm CWDM technology-based, single-mode fiber transmission distance up to 10km. Frequency interval based ITU-T G.694.2 specification, use the 1270,1290,1310 and 330nm 4 wavelengths, each wavelength channel rate is 10.3125Gbit/s. 40Gbit/s CFP optical module is a transmission mode in a single-mode optical fiber, to support 40Gbit/s Ethernet data rate transmission over four wavelengths in each wavelength 10.3125Gbit/s, and finally the use of WDM technology to four wavelengths of light composite signal transmitted over one single-mode fiber. 40Gbit/s CFP optical modules are mainly used in MAN, it can be converted into an electrical signal input optical signal output, in order to achieve long distance transmission, but also be able to receive the optical signal into an electrical signal output.

Active Optical Cable (AOC) application is a video and consumer electronics markets. 4K, 8K ultra-high resolution image is gradually into people's lives, these products and their applications involve the transmission of large amounts of data, but also need the support of optical interconnection technology.

PTN (Packet Transport Network) refers to an optical transport network architecture and specific technologies: IP traffic between the optical transmission medium and the underlying set a level for which the packet of bursty traffic statistical multiplexing and transmission requirements Designed to packet core business and supports multiple service provider, has a lower total cost of ownership (TCO), while inheriting traditional advantages of optical transmission, including high availability and reliability, efficient bandwidth management mechanisms and traffic engineering, convenient The OAM and network management, scalable, high security.
