The optical fibers in the optical fiber jumper mainly include OM1, OM2, OM3, OM4 multimode fiber and OS2 single mode. The connector types of the optical fiber jumper also include SC, ST, FC, LC, MTRJ and E2000. There is no fixed choice for these in specific use cases, and must be selected according to their own specific application conditions. How to choose the right patch cord for your internet?

1. Select the correct connector type (LC/SC/ST/FC/MPO/MTP)

Different connectors are used to plug into different machines. If the port numbers of the devices on both sides are the same, we can use the LC-LC/SC-SC/MPO-MPO jumper. If you want to connect devices with different port numbers, LC-SC/LC-ST/LC-FC jumpers may be suitable for you.

2. Select the type of single-mode or multi-mode fiber optic cable

Single-mode fiber jumpers use 9/125um fiber, and multi-mode fiber jumpers use 50/125um or 62.5/?125um fiber. Single-mode fiber patch cords are suitable for transmitting data over long distances. Multimode fiber optic patch cords are suitable for short-circuit transmission. The jacket of the general single-mode fiber optic patch cord is colored, while the jacket of the multi-mode fiber optic patch cord is orange or dark blue.

3. Choose simplex or duplex cable type

Simplex means that this fiber optic patch cord contains only one fiber optic cable with only one fiber optic connector at each end for dual (BIDI) fiber optic modules. Duplex can be regarded as two parallel optical fiber jumpers for general optical fiber modules.

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 choose an appropriate cable length according to the distance between the machines to be connected.

Five, choose the correct connector polishing type (UPC/APC)

Because APC connectors wear less than UPC connectors, generally, APC connectors have better optical properties than UPC connectors. In today's market, APC connectors are commonly used in more return loss sensitive applications such as FTTx, Passive Optical Internet (PON) and Wavelength Division Multiplexing (WDM). However, APC connectors are usually more expensive than UPC connectors, so you should consider whether you need APC connectors according to your specific situation. APC should be a consideration for these application sites that require high-precision fiber optic data signals, but other systems that are not particularly sensitive will perform as well as UPC. Usually, the color of fiber patch cords with APC connectors is green, and the color of UPC connectors is dark blue.

Six, choose the correct fiber jumper sheath (PVC/LSZH/OFNP/armored cable)

Generally, there are three types of jumper jackets: PVC, LSZH, OFNP. The jumper sheath made of PVC is commonly used, with average fire resistance and low price; the LSZH jumper sheath is made of low-smoke halogen-free raw materials, with good environmental protection and fire resistance, but the price is more expensive; OFNP jumper The sheath refers to the standard of the British Fire Safety Association, which can be flame retardant. This kind of material will automatically extinguish when it leaves an open flame. It is expensive and suitable for large data centers. Choose according to your own situation.
