The transceiver wavelengths of the optical modules at the two ends of the fiber jumper must be different, that is to say, the two ends of the fiber must be optical modules with the same wavelength. The simple way to distinguish is that the colors of the optical modules must be different. In a normal environment, short-wave optical modules use multi-mode optical fibers (orange optical fibers), and long-wave optical modules use single-mode optical fibers (yellow optical fibers) to ensure the accuracy of data transmission.
Do not wind and loop the optical fiber excessively during use, as this will increase the attenuation of the light in the transmission process.
After the fiber jumper is used, a protective sleeve must be used to protect the fiber. Dust and oil will damage the coupling of the fiber.
If the optical fiber is dirty, you can use a cotton swab dipped in alcohol to clean it, otherwise it will affect the communication quality.
1. Before use, the ceramic ferrule and end face of the fiber jumper must be wiped clean with alcohol and absorbent cotton.
2. Using time, the minimum bending radius of the fiber is not less than 150mm.
3. Protect the ferrule and the end face of the ferrule to avoid bruising and purification, and wear a dust cap immediately after disassembly.
4. Do not look directly at the end face of the optical fiber while the laser signal is transmitting.
5. The damaged fiber jumper should be replaced in real time when rewards and other irresistible damages are presented.
Optical fiber jumpers are used to make jumpers from equipment to optical fiber wiring links. There is a thicker shelter layer, which is generally used for the connection between the optical transceiver and the terminal box, and is used in some areas such as optical fiber communication system, optical fiber access network, optical fiber data transmission and local area network.
Optical fiber jumper (also known as optical fiber connector) means that the optical fiber cable is equipped with connector plugs at both ends to realize the connection of the optical path; one end with a plug is called a pigtail. Optical Fiber Patch Cord/Cable is similar to coaxial cable, except that there is no mesh barrier layer. In the middle is the glass core that transmits light. In a multimode fiber, the core diameter is 50μm~65μm, which is roughly commensurate with the thickness of a human hair. The single-mode fiber core has a diameter of 8 μm to 10 μm. A layer of glass envelope with a lower refractive index than the core is wrapped in the core to connect the optical fiber in the core. Inside is a thin layer of plastic coat to shelter the envelope.
Classification and overview of
optical fiber patch cords The following fiber patch cords (also known as fiber optic connectors), that is, the discussion of optical fibers connected to optical modules, have many types, and they are not mutually interoperable. The SFP module is connected to the LC fiber connector, and the GBIC is connected to the SC fiber connector. The above specific statement of several commonly used optical fiber connectors in the collection project:
①FC type optical fiber jumper: The internal reinforcement method is a metal sleeve, and the fastening method is a turnbuckle.
Ordinarily used on the ODF side (most used on the distribution frame) ②SC type optical fiber jumper: the connector connected to the GBIC optical module, its shell is rectangular, and the fastening method is a plug-in latch type without twisting. (The most used on router interchange machines)
③ST-type optical fiber jumper: often used in optical fiber distribution frame, the shell is round, and the fastening method is turnbuckle. (For 10Base-F connection, the connector is usually the ST model. It is often used in the optical fiber distribution frame)
④LC-type optical fiber jumper: the connector connected to the SFP module, which uses a convenient modular jack (RJ) latch The lock mechanism is made. (Routers are often used)
Jumper wire refers to an optical cable with abutting heads at both ends, and the optical cable is the central medium of the abutting heads. The former focuses on the connector, and the latter focuses on the medium that protects the optical fiber. If you add some attributions to the optical cable, such as "double-ended pre-connected optical cable", there is no big difference in quality from jumpers, but the focus of the former is still the cable (such as the change of the length of the optical cable, the change of the paradigm), and the focus of the latter is still "Connector" (a change in the connector paradigm). The composition of the optical fiber jumper is formed by the processing of the optical cable (optical fiber in the optical cable) and the connector. Simply speaking, the connector is connected through the optical cable to transmit the optical signal. The network cable is composed of a network cable (copper wire inside) and RJ45 crystal head processing. Used to transmit electrical signals
Jumper wire refers to the jumper wire connection from the connecting device to the optical fiber wiring link. There are joints at both ends and the protective layer is thick. It is usually used for the connection between the optical terminal and the junction box.
Telecommunications Bureau fiber to the enterprise. Under normal circumstances, dual-mode optical fiber is first transmitted to the enterprise host room, and then the optical fiber terminal is converted into RJ45 signal, then converted into the enterprise firewall, and then converted into the core, and converted into optical fiber through optical fiber transceiver and optical fiber patch cord. Optical fiber is transmitted to each branch office through the enterprise.
The connection method of the optical fiber jumper can only be determined according to the actual situation, so in order to reduce unnecessary troubles, it is more reassuring to find a professional construction team to install and debug.
Fiber optic transceivers generally use fiber optic transceivers, but the normal use of fiber optic transceivers and fiber switches, fiber optic transceivers and sfp transceivers may also occur. In principle, as long as the optical transmission wavelength is the same, the signal packaging format is the same, and both support the protocol, optical fiber communication can be realized.
Ordinary single-mode dual-fiber communication requires dual optical fibers. As long as a pair appears, the transceiver cannot be distributed to the transmitter and receiver.
Only a single optical fiber transceiver (a single optical fiber is required for normal communication) has a transmitter and a receiver. Whether it is a dual fiber transceiver or a single fiber transceiver, different brands are compatible. But the speed, wavelength, and mode need to be the same. In other words, different speeds and different wavelengths cannot communicate with each other, unless a single fiber transceiver of the same brand and a dual fiber dual fiber cannot be combined.
