1. Fiber connector and end-face type
Fiber patch cord have different fiber connector type : LC, SC,FC,ST,MTP/MPO etc. If you connect two devices with the same interfaces, you can use LC-LC, SC-SC patch cord with the same interface at both ends. If there are two devices with different interfaces, you can choose patch cord with different ends,such as LC-SC or LC-FC etc.
Commonly used end face type are APC and UPC. Because the optical fiber loss of APC type is lower than UPC type,so the optical performance of APC type is better than UPC type.The APC type are widely used in FTTX,PON and WDM fiber optic equipment that is more sensitive to return loss. But APC type are usually expensive than UPC type,so you should consider use APC or UPC according to your actual situation.
2.Choice of fiber type
Different fiber types of patch cords are suitable for different distances data transmission. Single mode patch cord are mainly used for long-distance data transmission. Multimode patch cord are mainly used for short-distance transmission.
3.Choice of Simplex or Duplex type patch cord
There is only one fiber optic connector at both ends of the simplex patch cord,it has only one fiber inside,and data can only be transferred in one direction.
Duplex patch cord have two connectors at each end,it has two fiber inside,Duplex patch cord can realize two way transmission of data,it is commonly used in various duplex communication applications,such as fiber optic switches and servers,fiber optic modems ,etc.According to the interface of your connected Fiber optical equipment to choose.
4.Fiber patch cord length and outer jacket
Fiber patch cord length is usually 0.5m-100m,choose the appropriate patch cord length according to the distance between the devices you need to connect. The outer jacket is usually PVC, PVC, LSZH, OFNP, Armored material,You can choose according to the place where the jumper is used : PVC jacket is cheap,and soft resistant to oxidation,used for horizontal and vertical runs in a contained ventilation building ; LSZH jacket make little smoke and no halogen,suited for horizontal structure cabling areas ; OFNP jacket have the highest fire rating,suited for large indoor data centers.
