光纖跳線(又稱光纖連接器)是指光纜兩端都裝上連接器插頭，用來實現光路活動連接;一端裝有插頭則稱為光纖尾纖。
Optical fiber patchcord (also known as optical fiber connector) refers to the fact that both ends of the optical cable are equipped with connector plugs to realize the active connection of the optical path; the optical fiber pigtail is called with a plug at one end。
光纖跳線用來做從設備到光纖布線鏈路的跳接線。有較厚的保護層，一般用在光端機和終端盒之間的連接。
Optical fiber Patchcord are used to make patch cords from equipment to optical fiber wiring links. There is a thick protective layer, which is generally used in the connection between the optical transceiver and the terminal box.
光纖尾纖是只有一端有連接頭，而另一端是一根光纜纖芯的斷頭，通過熔接與其他光纜纖芯相連，常出現在光纖終端盒內，用於連接光纜與光纖收發器（之間還用到耦合器、跳線等）。
Optical fiber pigtails have only one end with a connector, and the other end is a broken end of an optical fiber core. It is connected to other optical fiber cores by fusion splicing. It often appears in the optical fiber terminal box and is used to connect the optical fiber cable to the optical fiber transceiver. Couplers, patchcord, etc. are also used).
光纖連接器是光纖與光纖之間進行可拆卸（活動）連接的器件，它是把光纖的兩個端面精密對接起來，以使發射光纖輸出的光能量能最大限度地耦合到接收光纖中去，並使由於其介入光鏈路而對系統造成的影響減到最小，這是光纖連接器的基本要求。在一定程度上，光纖連接器也影響了光傳輸系統的可靠性和各項性能。
The optical fiber connector is a device that can be detached (movably) connected between the optical fiber and the optical fiber. It is a precise butt joint of the two end surfaces of the optical fiber, so that the optical energy output by the transmitting fiber can be coupled to the receiving fiber to the maximum extent. And to minimize the impact on the system due to its involvement in the optical link, this is the basic requirement of fiber optic connectors. To a certain extent, fiber optic connectors also affect the reliability and performance of optical transmission systems.
光纖跳線（Optical Fiber Patch Cord/Cable)和同軸電纜相似，只是沒有網狀屏蔽層。中心是光傳播的玻璃芯。
在多模光纖中，芯的直徑是50μm~65μm，大致與人的頭髮的粗細相當。而單模光纖芯的直徑為8μm~10μm。芯外面包圍著一層折射率比芯低的玻璃封套，以使光纖保持在芯內。再外面的是一層薄的塑料外套，用來保護封套。
Optical fiber patch cord (Optical Fiber Patch Cord/Cable) is similar to coaxial cable, except that there is no mesh shield. At the center is a glass core for light propagation.
In multimode fiber, the diameter of the core is 50μm~65μm, which is roughly equivalent to the thickness of human hair. The diameter of single-mode fiber core is 8μm~10μm. The outside of the core is surrounded by a glass envelope with a lower refractive index than the core to keep the optical fiber in the core. Outside is a thin layer of plastic jacket to protect the envelope.
光纖跳線的分類
Classification of fiber optic Patchcord
光纖跳線按傳輸媒介的不同可分為常見的矽基光纖的單模、多模跳線，還有其它如以塑膠等為傳輸媒介的光纖跳線；
Optical fiber patchcord can be divided into common single-mode and multimode patchcord for silicon-based optical fibers according to different transmission media, as well as other optical fiber patchcord that use plastic as the transmission medium.
按連接頭結構形式可分為：FC跳線、SC跳線、ST跳線、LC跳線、MTRJ跳線、MPO跳線、MU跳線、E2000跳線、等各種形式。比較常見的光纖跳線也可以分為FC-FC、FC-SC、FC-LC、FC-ST、SC-SC、SC-ST等。
單模光纖(Single-mode Fiber)：一般光纖跳線用黃色表示，接頭和保護套為藍色；傳輸距離較長。
According to the structure of the connector, it can be divided into: FC jumper, SC jumper, ST jumper, LC jumper, MTRJ jumper, MPO jumper, MU jumper, E2000 jumper, and other forms. The more common fiber patchcord can also be divided into FC-FC, FC-SC, FC-LC, FC-ST, SC-SC, SC-ST, etc.
Single-mode fiber (Single-mode Fiber): Generally, the fiber jumper is indicated by yellow, and the connector and protective sleeve are blue; the transmission distance is longer.
多模光纖(Multi-mode Fiber)：一般光纖跳線用橙色表示，也有的用灰色表示，接頭和保護套用米色或者黑色；傳輸距離較短。
Multi-mode fiber (Multi-mode Fiber): Generally, the fiber patchcord are indicated in orange, and some are indicated in gray. The connectors and protective sleeves are beige or black; the transmission distance is short.
光纖跳線使用注意事項
Precautions for using optical fiber jumper
光纖跳線兩端的光模塊的收發波長必須一致，也就是說光纖的兩端必須是相同波長的光模塊，簡單的區分方法是光模塊的顏色要一致。
光纖在使用中不要過度彎曲和繞環，這樣會增加光在傳輸過程的衰減。
光纖跳線使用後一定要用保護套將光纖接頭保護起來，灰塵和油汙會損害光纖的耦合。如果光纖接頭被弄髒了的話，可以用棉籤蘸酒精清潔，否則會影響通信質量。
The transmit and receive wavelengths of the optical modules at both ends of the fiber jumper must be the same, that is to say, the two ends of the optical fiber must be optical modules of the same wavelength. The simple way to distinguish is that the color of the optical module must be the same.
Do not excessively bend or loop the fiber during use, as this will increase the attenuation of light during transmission.
After using the fiber jumper, be sure to protect the fiber connector with a protective sleeve. Dust and oil will damage the coupling of the fiber. If the fiber connector is dirty, you can clean it with a cotton swab dipped in alcohol, otherwise it will affect the communication quality.
1、使用前必須將光纖跳線陶瓷插芯和插芯端面用酒精和脫脂棉擦拭乾淨。
2、使用時光纖最小彎曲半徑小於30mm。
3、保護插芯和插芯端面，防止碰傷、汙染，拆卸後及時帶上防塵帽。
4、雷射信號傳送之時請勿直視光纖端面。
5、出現人為及其它不可抗因素損壞時應及時更換損壞的光纖跳線。
6、光纖網絡或系統出現異常情況，可採用故障排除法逐一測試。測試或排除跳線故障時可以先做通斷測試，通常可以使用可見雷射筆對整個光纖鏈路打光判斷。或者進一步使用精密光纖插損回損儀，測試其各項指標，指標在合格範圍內，則跳線指示正常，反之則不合格。
1. The ceramic ferrule and the end face of the fiber jumper must be wiped clean with alcohol and absorbent cotton before use.
2. The minimum bending radius of the optical fiber is less than 30mm.
3. Protect the ferrule and the end surface of the ferrule to prevent bumps and pollution. Bring a dust cap in time after disassembly.
4. Do not look directly at the end of the fiber when the laser signal is transmitted.
5. When man-made and other force majeure factors are damaged, the damaged optical fiber jumper should be replaced in time.
6. Abnormal situations in the optical fiber network or system can be tested one by one by the troubleshooting method. When testing or eliminating jumper faults, you can do the continuity test first, and you can usually use a visible laser pointer to judge the entire fiber link. Or further use a precision optical fiber insertion loss return loss instrument to test its various indicators. If the indicator is within the qualified range, the jumper indicates normal, otherwise it is not qualified.

Carrier-grade fiber patch cords have the characteristics of low insertion loss, good repeatability, good interchangeability, and good environmental adaptability, so they are widely used in important network environments, such as national defense readiness, data center computer rooms, fiber-to-the-home, backbone LAN, etc.
光纖跳線中FC\ST\SC\LC\MTRJPC\APC\UPC各代表什麼？
FC、ST、SC、LC、MTRJ是物理接口連接方式不同。
FC是圓形螺旋口。
ST是圓形45度卡口。
SC是方型插口。
What does FC\ST\SC\LC\MTRJPC\APC\UPC represent in the fiber jumper?
FC, ST, SC, LC, MTRJ are different physical interface connection methods.
FC is a round spiral mouth.
ST is a round 45 degree bayonet.
SC is a square socket.
LC和MTRJ是小插芯連接口，在國內用的比較少，但是部分進口設備上帶。
PC、APC、UPC代表陶瓷插芯的前端面結構！
LC and MTRJ are small ferrule connectors. They are rarely used in China, but some imported equipment comes with them.
PC, APC, UPC represent the front-end structure of ceramic ferrules!
PC是球面結構，APC是斜8度角結構，UPC是超平面結構。
多模光纜的連接距離要短的多，是300米或500米（主要看雷射的不同，產生短波長雷射的光源一般有兩種，一種是62.5的，一種是50的）
光纖跳線一般常用規格如勝為光纖跳線，有1米，3米，5米，10米，15米等，如果需要其它特殊長度規格的光線跳線，就可以讓勝為廠家來定做，長度任意定製，一般幾公裡之內都是沒有問題的。另外，光纖跳線著重一個跳字，一般都是稍短些，用在機房、光纖入戶，光纖模塊等設備上面，如果是遠距離拉光纖，這種普通的光纖跳線是用不上的，需要定製那種皮線光纜或者鎧裝光纜都可以的。
PC is a spherical structure, APC is an oblique 8-degree angle structure, and UPC is a super-planar structure.
The connection distance of the multimode optical cable is much shorter, 300 meters or 500 meters (mainly depends on the difference of the laser, there are generally two types of light sources that generate short-wavelength lasers, one is 62.5 and the other is 50)
Fiber optic patchcord are generally used in specifications such as fiber optic patchcord, which are 1 meter, 3 meters, 5 meters, 10 meters, 15 meters, etc. If you need other special length optical fiber patchcord, you can let Shengwei customize it. The length is arbitrarily customized, generally within a few kilometers is no problem. In addition, the fiber optic jumper emphasizes a jumper, which is generally shorter. It is used in equipment rooms, fiber homes, fiber optic modules and other equipment. If the fiber is pulled from a long distance, this ordinary fiber jumper is not used. , You need to customize the kind of leather cable or armored cable.
步驟1：選擇正確的接頭類型(LC / SC / ST / FC / MPO / MTP)
不同的接頭用於插入不同的設備。如果兩端設備的埠相同，我們可以使用LC-LC / SC-SC / MPO-MPO跳線。如果要連接不同的埠類型設備，LC-SC / LC-ST / LC-FC跳線可能適合您。
步驟2：選擇單模或多模光纜類型？
單模光纖跳線採用9 / 125um光纖，多模光纖跳線採用50 / 125um或62.5 / 125um光纖。單模光纖跳線主要用於長距離數據傳輸。多模光纖跳線主要用於短距離傳輸。一般的單模光纖跳線的護套為黃色，而多模光纖跳線的護套則為橙色或者藍色。
步 驟3：選擇單工或雙工光纜類型？
單工意味著此光纖跳線只帶有一根光纜，每端只有一個光纖連接器，用於雙向（BIDI）光模塊。雙工可以看成是並排的兩根光纖跳線，用於普通光模塊。
步驟4：選擇正確的跳線長度（1m / 5m / 10m / 20m / 30m / 50m）
光纖跳線長度不同，通常為0.5m至50m。您應根據要連接的設備之間的距離選擇適當的電纜長度。
步驟5：選擇正確的連接器拋光類型（UPC / APC）
由於APC連接器的損耗低於UPC連接器，通常，APC連接器的光學性能優於UPC連接器。在當前市場中，APC連接器廣泛地用於諸如FTTx，無源光網絡（PON）和波分復用（WDM）的對回波損耗更敏感的應用中。但是APC連接器通常比UPC連接器貴，所以你應該根據自己的實際情況來考慮是否需要APC連接器。對於那些要求高精度光纖信號的應用場所來說，APC應該是第一個考慮因素，但是其他不太敏感的系統將使用UPC同樣表現良好。通常，採用APC連接器的光纖跳線顏色為綠色，而採用UPC連接器的顏色為藍色。
步驟6：選擇正確的護套（PVC / LSZH / OFNP /鎧裝）
通常，有三種跳線護套類型：PVC、LSZH、OFNP。PVC材質的跳線護套就是一般大家所常見的，防火能力一般，價格最低；LSZH跳線護套由低煙無滷材料製成，環保和阻燃性能較好，但是價格比較貴；OFNP跳線護套指的是美國防火委員會標準，能夠阻燃，這種材質離開火源會自動熄滅，價格最貴，適用於大型數據中心。您可以根據自己的情況進行選擇。除了上述三條跳線之外，還有另外一種鎧裝。它的鋼套管結構使能夠很好的保護脆弱的光纖，抗彎曲能力比較強。這種跳線可以承受更高的壓力，所以它們適合沿著地板和其他可能被踩踏的區域布線。這種光纖跳線還具有耐磨性強、抗拉扯、防鼠咬等優點。
Step 1: Select the correct connector type (LC / SC / ST / FC / MPO / MTP)
Different connectors are used to insert different devices. If the ports on both ends are the same, we can use LC-LC / SC-SC / MPO-MPO patchcord. If you want to connect devices with different port types, LC-SC / LC-ST / LC-FC patchcord may be suitable for you.
Step 2: Choose single-mode or multi-mode cable type?
Single-mode fiber patchcord use 9/125um fiber, and multimode fiber patchcord use 50/125um or 62.5/125um fiber. Single-mode fiber patchcord are mainly used for long-distance data transmission. Multimode fiber patchcord are mainly used for short-distance transmission. The jacket of a general single-mode fiber jumper is yellow, and the jacket of a multimode fiber jumper is orange or blue.
Step 3: Choose simplex or duplex fiber optic cable type?
Simplex means that this fiber jumper has only one fiber optic cable and only one fiber optic connector at each end for bidirectional (BIDI) optical modules. Duplex can be seen as two optical fiber patchcord side by side, used for ordinary optical modules.
Step 4: Choose the correct jumper length (1m / 5m / 10m / 20m / 30m / 50m)
The length of the fiber jumper is different, usually 0.5m to 50m. You should select the appropriate cable length according to the distance between the devices to be connected.
Step 5: Select the correct connector polishing type (UPC/APC)
Since the loss of the APC connector is lower than that of the UPC connector, in general, the optical performance of the APC connector is superior to that of the UPC connector. In the current market, APC connectors are widely used in applications such as FTTx, passive optical network (PON) and wavelength division multiplexing (WDM) that are more sensitive to return loss. But APC connectors are usually more expensive than UPC connectors, so you should consider whether you need an APC connector according to your actual situation. For applications that require high-precision fiber optic signals, APC should be the first consideration, but other less sensitive systems will also perform well using UPC. Generally, the color of the fiber jumper using the APC connector is green, and the color of the UPC connector is blue.
Step 6: Choose the right jacket (PVC/LSZH/OFNP/Armor)
Generally, there are three types of jumper jackets: PVC, LSZH, and OFNP. The jumper jacket made of PVC is common to everyone. The fire resistance is average and the price is the lowest. The LSZH jumper jacket is made of low-smoke and halogen-free materials. It has better environmental protection and flame retardant performance, but the price is more expensive. OFNP jumper The wire jacket refers to the American Fire Protection Committee standard, which can be flame retardant. This material will automatically extinguish when it leaves the fire source. The price is the most expensive and suitable for large data centers. You can choose according to your own situation. In addition to the above three patchcord, there is another kind of armor. Its steel sleeve structure makes it possible to protect the fragile optical fiber very well, and its bending resistance is relatively strong. Such patchcord can withstand higher pressures, so they are suitable for wiring along the floor and other areas that may be trampled. This optical fiber jumper also has the advantages of strong wear resistance, anti-pull, anti-rat bite and so on.
