Optelian released two new 100G muxponder product
11/25/15  |  Industry News  |

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

Principle and application of optical fiber communication
9/20/15  |  Technical Article  |

Principle of optical fiber communication is first necessary to transfer in the sender information (such as voice) into electrical signals, and then modulated onto the laser beam emitted from the laser, so that the intensity of light with the electric signal amplitude (frequency) changes, and sent through an optical fiber; at the receiving end, the detector receives the optical signal converts it into an electric signal, after demodulation to restore the original information.

Fiber jumpers range of product applications
9/5/15  |  Technical Article  |

Fiber Jumper products are widely applied to: the communications room, fiber to the home, local area networks, fiber optic sensors, fiber optic communication systems, fiber optic transmission equipment connected, defense readiness and so on. It applies to cable television, telecommunications networks, computer networks and fiber optical test equipment. Broken down mainly used in several ways.

EPON - Ethernet Passive Optical Network
8/25/15  |  Technical Article  |

EPON is the best combination of several technology and network structure. EPON uses multipoint structure, passive optical transmission, offers a variety of services over Ethernet. At present, IP/Ethernet applications accounted for more than 95% of the entire LAN communication, EPON since the economic and efficient use of the above-described structure, will become an end-user access network connecting the most efficient communication method.

PTN technology concepts
8/23/15  |  Technical Article  |

PTN technology is essentially a packet-based routing architecture to provide multi-service technical support. It is a more suitable for IP service transmission technology, while inheriting the traditional advantages of optical transmission, including a good network scalability, a rich operation and maintenance (OAM), fast protection switching and clock transmission capability, high reliability and safety sex, the whole concept of network management, end to end service configuration and precise alarm management. These advantages PTN is the traditional router and Enhanced Ethernet technology can not match, which is distinct from the important attributes of both. We can understand the concept of PTN technology from the following four aspects.

OADM classification and characteristics
8/17/15  |  Technical Article  |

The main function of OADM is separated from the multi-wavelength channels or insertion of one or more wavelengths, there are fixed and reconfigurable two types.

Optical Access Scope
8/4/15  |  Technical Article  |

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.

Fiber Access
7/31/15  |  Technical Article  |

Fiber access refers to the complete optical fiber as a transmission medium between the central office and the users. Fiber access can be divided into active and passive optical access. Main fiber optic network is lightwave transmission technology. Development of optical transmission multiplexing quite rapidly, most have been in practical use.

SDH is the development direction of digital transmission network
7/20/15  |  Technical Article  |

SDH its obvious superiority transmission network has become the mainstream of development. SDH technology and some advanced technology, such as optical wavelength division multiplexing (WDM), ATM technology, Internet technology (Packet over SDH), so that the role of SDH network is growing. SDH has been included in various countries in the 21st century high-speed communications network application project is the development direction of the telecommunications industry recognized digital transmission network, with great commercial prospects.

Advantages and application of high-speed optical interconnection
6/11/15  |  Technical Article  |

Data center / cloud computing system needs higher bandwidth and lower power consumption and more urgent, AOC is one of the best solutions to meet this demand. AOC (active optical cables) compared with the copper interconnect has many significant advantages, such as lower on the system link transmission power, weighs only a quarter of direct-attached copper, copper-half volume slightly, and room cabling system has better air flow heat dissipation than copper cable bend radius can be made smaller, over longer distances (up to 100 to 300 meters), and the error rate is also better transmission performance , BER can reach 10 ^ -15. Compared with the optical transceiver module, AOC is not exposed due to the presence of optical interface, optical interface clean and contaminated problem does not exist, the system greatly enhanced stability and reliability, and reduce maintenance costs the engine room.
