The optical fiber unit, Pre-terminated Drop Cable, is positioned in the center.Two parallel Fiber Reinforced Plastics (FRP) are placed at the two sides.Then,the cable is completed with a black or color LSZH sheath. It is also called leather cable. It is a new type of user access optical cable. According to the application environment and laying conditions, the cable structure and various technical parameters are reasonably designed. The characteristics of indoor soft cable and self-supporting optical cable are collected. Special equipment is used in conjunction with imported precision mold production. It is the best candidate for FTTX network solution, and it is also suitable for users of other fiber-optic FTTO and FTTB networks. Because the cross-section is like a butterfly, it is called a butterfly cable. Both sides are reinforcing members in the leather line and optical fibers in the middle.
The structure of the self-supporting pre-terminated drop cable is based on the Butterfly cable, and a metal suspension unit is added. With the continuous extension of the optical fiber like the user end, in order to meet the different uses and requirements, and expand the use range of the butterfly-introducing cable, on the basis of the Pre-terminated Drop Cable, a derivative product of the butterfly-introducing has emerged, the most typical one being The Self-supporting Pre-terminated Drop Cable is introduced into the optical cable.READ MORE
GPON-4081 Optical modem is the abbreviation of modulator and demodulator. Chinese called modem (known as the data machine in Hong Kong and Taiwan). According to the homophonic sound of Modem, it is called "cat" relatives. It is a device that converts a digital signal into an analog signal by modulation at the transmitting end and converts the analog signal into a digital signal by demodulating at the receiving end. The so-called modulation is to convert the digital signal into an analog signal transmitted on the telephone line; demodulation, that is, converting the analog signal into a digital signal. The so-called modem. The English language of the modem is MODEM, which is used as a "translator" for analog signals and digital signals.
The 40G optical module refers to an optical module with a transmission rate of 40 Gbps. CFP and QSFP are the main package types, and the 40G QSFP optical module is one of the most widely used. The 40G QSFP+ optical module is typically used with LC single-mode fiber patch cords for transmission distances up to 10km, and it has four data channels that simultaneously transmit data. It works by the laser driver controlling the wavelength of arrival, and the optical signals are then multiplexed and combined for transmission. When the receiver arrives at the receiving end, the transmitted signals are decomposed into four channels with a transmission rate of 10 Gbps, and then the PIN detector or transimpedance amplifier recovers the data stream and then transmits the optical signal.
OC240-Cross Connecting Cabinet is use for outdoor cable access network, backbone cable and indoor cable arrangement. it with high-capacity, high-density fiber distribution tray, suitable for the composition, splice and distribution of fibers in optical access network to achieve the fiber optic lines connection, distribution and scheduling.The oc240-cross connecting cabinet is a kind of outdoor cabinet. It refers to a cabinet made of metal or non-metal materials directly under the influence of natural weather. It does not allow unauthorised operators to enter the operating cabinet, providing wireless communication stations or wired network station workstations.
Professional fiber manufacturer from Guangdong province, China. The structure of GYTA53 optical cable is to insert a single-mode or multi-mode optical fiber into a loose tube made of a high modulus polyester material, and the casing is filled with a waterproof compound. A fiber reinforced plastic (FRP) locates in the center of core as a non-metallic strength member.
GY-Outdoor optical cable for communication,X-Central tubular structure,T-Filled,W-Steel polyethylene bonded sheath with steel wire. GYXTW fiber optic cable, 250um, in a loose tube made of high modulus plastic. The tubes are filled with a water-resistant filling compound, mainly for the longitudinal water blocking of the fiber and the compactness of the fiber. The tube is wrapped with a layer of PSP longitudinally. Between the PSP and the loose tube water-blocking material is applied to keep the cable compact and watertight. Two parallel steel wires are placed at the two sides of the steel tape.
BIDI-SFP optical module: BiDi (Bidirectional): single fiber bidirectional. It uses WDM (ie, wavelength division multiplexing) technology to transmit and receive different center wavelengths in two directions, thereby realizing a bidirectional transmission of optical signals in one fiber. A general optical module has two ports, a TX transmitting port and an RX receiving port, and the BIDI optical module has only one port, which is filtered by a filter in the optical module, and simultaneously performs transmission of a 1310 nm optical signal and reception of a 1550 nm optical signal, or in contrast. Therefore, BIDI modules must be used in pairs. It is a hot-swappable input/output device that plugs into a Gigabit Ethernet port or slot, linking the port with the network. SFPs can be used and interchanged on a wide variety of switches and routers, can be intermixed in combinations of 1000BASE-T, 1000BASE-SX, 1000BASE-LX/LH, 1000BASE-EX, 1000BASE-ZX, or 1000BASE-BX10-D/U on a port-by-port basis.
