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.

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.

(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.

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.

Both ends of the optical fiber jumper wavelength transceiver module must be consistent, meaning that both ends of the fiber must be the same wavelengths of light module, a simple distinction is the color of the light module to be consistent. Under normal circumstances, short-wave optical module using multimode fiber (orange fiber), long wavelength module uses single-mode fiber (yellow fibers), in order to ensure the accuracy of data transmission.

Fiber optic patch cords are used as devices to the jumper fiber optic cabling links. It has a thick layer of protection, generally used in the connection between the Optical and the terminal box.

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:

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.

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.
