Fiber optic connector common knowledge
11/13/15  |  Technical Article  |

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.

How fiber work?
11/4/15  |  Technical Article  |

Communication with the fiber from the outer cover of plastic protective layer composed of glass as thin as a hair. Glass substantially consists of two parts: the core diameter of 9 to 62.5μm, the cover having a diameter of 125μm low refractive index of a glass material. Although according to the materials used and the dimensions of different points there are other types of fiber, but mentioned here are the most common that several. Light in the core portion of the fiber to the "total internal reflection" mode for transmission, but also refers to an end after the light enters the fiber, at the interface between the core and the cladding reflected back and forth, and then transferred to the other end of the fiber. Core diameter of 62.5μm, cladding outer diameter of 125μm fiber called 62.5/125μm light.

Fiber common knowledge

①FC fiber optic jumper: External reinforce way is to use a metal sleeve, fastening means for the turnbuckle. ODF side in general use. (For use on patch panel Up)
②SC fiber optic jumper: connection GBIC optical modules, its shell is rectangular, a plug pin fastening bolt type, do not need to rotate. (Used on most routers switches)

OFS Release TeraWave ™ ULL ultra-low-loss optical fiber
10/9/15  |  Industry News  |

Innovative provider of world-class design and production company OFS fiber optic network equipment and solutions, recently expanded the overland distance applications, the introduction of ultra-low-loss optical fiber TeraWave ™ ULL than G.652.D 50% larger effective area fiber and 1550nm attenuation of less than 0.17dB/km. For the growth of T-bit transmission market, OFS's TeraWave ULL optical fiber is ultra-low-loss version designed to improve system performance TeraWave coherent long-distance optical fiber. TeraWave fiber has a longer transmission distance and accommodate more wavelengths than the ITU-T G.652.D fiber, reducing the need for expensive signal relay.

Avago Introduces New Low-Power Fiber Transceiver
9/24/15  |  Industry News  |

American Avago Tech 16 officially launched an ultra-low power consumption, small plug-in Fast Ethernet fiber optic transceivers AFBR-57E6APZ, designed for industrial automation, control and network applications and other fields.

CommScope / OFS Release SWDM with multimode fiber
9/22/15  |  Industry News  |

CommScope has introduced broad-based with its SYSTIMAX LazrSPEED 550 multimode fiber WBMMF cable products. This fiber can support four wavelengths 850nm to 950nm transmitted simultaneously, rather than that single wavelength ordinary OM4 fiber. CommScope OFC once during the year, and Finisar exhibited together with the application of short-wavelength WDM optical modules and this fiber. The use of this fiber provides a new option for reducing costs from 40G to 400G optical modules of various types. In addition, this fiber also supports traditional OM4 fiber applications.

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.

Optical fiber communication system basic configuration
9/16/15  |  Technical Article  |

(1) Light transmitter
Light transmitter is to achieve electrical / optical conversion of Optical. It consists of a light source, driver and modulator. Its function is to electrical signals from the electrical end machine for light emitted from the light source is modulated, become modulated light, and then the modulated optical signal is coupled into an optical fiber or optical cable to transmit. Electric end machine is conventional electronic communication devices.

How to reduce the fiber optic fusion splice loss
9/8/15  |  Technical Article  |

After the fiber splicing, the light transmitted to the optical fiber splice joints will have a certain amount of loss, called splice loss. Optical fiber splice loss is mainly composed of an optical fiber transmission loss and splice loss itself constituted. As the quality of fiber optic splice fiber-optic lines will result in transmission loss, optical line transmission distance and other factors, therefore, to minimize fiber optic fusion splice loss, in order to ensure the transmission quality of the fiber CATV signals.
