what are the types of fiber jumpers?

(1) Classification by fiber type

1. Single mode fiber patch cord: generally yellow, the connector and protective cover are blue, and the transmission distance is long.

2. Multimode fiber patch cord: generally orange or water blue, the connector and protective cover are beige or black, and the transmission distance is short.

(2) Classification by connector type

Fiber patch cords can be classified into FC, ST, SC, LC, MU, E2000, MTRJ, SMA, etc. according to the connector. The following is a detailed description of commonly used fiber jumpers:

1. FC fiber jumper

The FC (Ferrule Connector) fiber patch cord is one of the most common connected devices in a single mode network. Its external reinforcement method is a metal sleeve, and the fastening method is a turnbuckle. Common on the ODF side (most seen on the patch panel). The FC connector is generally used in a large number of telecommunication networks. Its advantage is that it is reliable and dust-proof. The disadvantage is that the installation time is slightly longer.

2. ST fiber jumper

ST (Stab & Twist) fiber patch cords are the most common connection devices in multimode networks and are the more common types of connectors in Base10 fiber connections. Often used on fiber distribution frames. The outer casing is round, and the fastening method is a turnbuckle. The core is exposed, and it needs to be inserted first, and then the half-cycle fixed bayonet is rotated.

3. SC fiber patch cord

The SC (Square Connector) fiber patch cord is a TIA-568-A standardized connector. It was not widely used at an early stage due to its high price. It was gradually used in connection with GBIC optical modules due to its excellent performance. Commonly found on router switches, the outer casing is rectangular, and the fastening method is plug-and-pull type. Unlike ST/FC, it does not need to be rotated.

4. LC fiber patch cord

The LC (Lucent connector) fiber patch cord is usually connected to the SFP optical module. The connector is similar to the SC connector but smaller than the SC connector. The size of the pin and the sleeve is 1.25mm, which is half of the ordinary SC and FC. The fastening method is the jack latch. Its advantages and performance are good, which can improve the density of the fiber connector in the fiber distribution frame to a certain extent, and is a good single mode fiber jumper.

(3) Classification by application of jumpers

Optical fiber jumpers are generally classified into MTP/MPO fiber jumpers, conventional fiber jumpers, and armored fiber jumpers.

1. MTP/MPO fiber jumper: It is common in a fiber-optic line environment where high-density integration is required in the wiring process. Its advantages are: easy to install and remove, save time and cost, and maximize the service life.

2. Armored fiber optic patch cords: Common in the machine room, suitable for use in harsh environments. Its advantages: no need to use protective casing, can prevent moisture and fire, have antistatic and acid and alkali resistance, can save space and reduce construction cost.

3. Conventional Fiber Patch Cables: Conventional Fiber Patch Cables are OS2 9/125 Single Mode Simplex, OM4 40/100Gb 50/125 Multimode, OM3 10Gb 50/125 Multimode, OM2 50/125 Multimode, OM1 62.5/125 Multimode, OS2 9/125 single mode simplex, OM5 50/125 multimode these types.

Among them, OM5 fiber patch cord is a popular product, which is often used for higher bandwidth. The outer sheath is water green, with strong scalability, compatibility, and interoperability, which can effectively reduce costs.
