What are the models of multimode fiber optic jumpers?
Generally, it is divided according to the connector. The conventional ones include SC, FC, LC, ST, and MPO. According to the type of fiber core, it can be divided into single-mode, multi-mode, dual-core, single-core, Gigabit, 10 Gigabit, etc.
Multimode fiber jumper points: SC FC ST LC MTRJ SC and LC are square heads (SC is a large square head, LC is a small square head) FC and ST are round heads, and the color green is carrier-grade, which is APC (now there are also The ones that are not green are carrier-grade jumpers, depending on how the manufacturer does it. The blue is for SC connectors. Generally, only SC has black. The ones that are black are FC and ST. (The network level is generally used for short-distance network transmission. Equipment such as optical fiber transceivers and switches can be used for terminal optical fiber fusion. The advantage is that the loss of the network is large, and the loss of telecommunications is small.
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, SMA jumper, FDDI jumper, E2000 jumper, DIN4 Jumper, D4 jumper, etc. in various forms. The more common fiber optic jumpers can also be divided into FC-FC, FC-SC, FC-LC, FC-ST, SC-SC, SC-ST, etc.
Multi-mode fiber (MulTI-mode Fiber): Generally, fiber optic jumpers are represented by orange, and some are represented by gray, and the connectors and protective sleeves are beige or black; the transmission distance is short.
What are the commonly used models of 8-core multimode optical cables?
The 8-core optical cable is a communication cable with 8 optical fibers (composition of silica, quartz glass) built in. With a variety of structural models and two transmission modes, it is a widely used communication optical cable.
In terms of model selection, the 8-core optical cable mainly has two types of outdoor and indoor models. The outdoor models include GYXTW, GYTS, GYTA, and GYTA53; the indoor models include GJFJV.
1. GYXTW: central beam tube type armored structure, can accommodate 4-12 cores, suitable for overhead laying.
2. GYTS: Layer stranded armored structure, can accommodate 4-144 cores, suitable for buried and pipeline laying. (It needs to be covered with a layer of PVC pipe when buried)
3. GYTA: Layer stranded aluminum structure, can accommodate 4-144 cores, suitable for buried and pipeline laying. (It needs to be covered with a layer of PVC pipe when buried)
selection guide
The nominal diameter of the core wire of the multimode fiber is 62.5μm/125μm. or 50μm/125μm. Specifications (number of cores) include 2, 4, 6, 8, 12, 16, 20, 24, 36, 48, 60, 72, 84, 96 cores, etc. The outer sheath material of the cable has ordinary type; ordinary flame retardancy; low-smoke halogen-free type; low-smoke halogen-free flame-retardant type.
Multimode fiber optic cable selection:
In addition to the number of optical fiber cores and types of optical fibers, the selection of optical cables also requires the outer sheath of the optical cable to be selected according to the use environment of the optical cable. The application of optical fiber networks is very common. We must choose optical cables with reasonable structures according to the specific construction requirements, such as optical cables If you want to bury directly without wearing pipes, and use overhead or buried pipes, you need to choose optical cables with different structures. Armored optical cables are commonly used for aerial and pipe penetration. Generally, GYXTW central beam tube armored optical fiber cable or GYTA loose sleeve layer Stranded armored optical fiber cable, GYTS layered armored optical cable, etc. Metal heavy armored optical cable for direct burial is generally layered structure such as: GYTA53 loose sleeve layered reinforced core armored optical cable, GYTY53 single armored double sheath Non-metallic optical cables are used for direct buried optical cables, electric power, and industrial control optical cables, such as: ADSS power optical cables, DCHTY loose-tube stranded non-metallic reinforced core optical cables, and the following different modes can be selected according to different optical fiber lengths and network bandwidth requirements.
