Fiber Patch Leads

Fiber patch leads, called fiber optic patch cords, are fiber optic cables pre-terminated with connectors at each end to connect network devices quickly. It is an essential component of any fiber optic network. It is mainly used to connect the optical transceiver and the terminal box. Fiber optic leads are widely used in applications such as telecom, datacom, and local area networks. It can be used in cable TV, communication, and optical test equipment.

fiber patch leads

Fiber patch leads include two main components: the fiber optic cable and the connectors at both ends. The connectors on both ends can be of the same type or different. They include LC, ST, SC, FC, MT-RJ, MU, etc. On the other hand, fiber optic cables are available in simplex (1 fiber) and duplex (2 fibers). They can also be single-mode or multimode fibers. In addition, the fiber optic patch cords have a thicker protective layer to protect the optical cable.

Bwnfiber presents a diverse array of fiber patch leads or patch cords, many are ready for immediate shipment. Our range includes both single-mode and multimode patch leads. In addition, we provide armored variants, including 9/125, 50/125, 62.5/125, 10Gb OM3, OM4, OM5, etc. On the other hand, Bwnfiber can also tailor products to your needs. We offer fiber optic patch cable lengths of 1M, 2M, 3M, 5M, 10M, etc. Our jacket material is PVC and LSZH. Over the years, our fiber patch lead products have covered the USA, UK, Turkey, South Africa, Brazil, Chile, Saudi Arabia, Spain, UAE, etc.

Connector of Fiber Patch Leads

The connector types of fiber patch leads include LC, FC, ST, SC, MU, E2000, MTRJ, SMA, MPO/MTP, etc. Different connectors are used to plug into different devices. If the ports of the devices at both ends are the same, we can use an LC-LC / SC-SC / MPO-MPO patch cord. If you want to connect different port-type devices, the LC-SC / LC-ST / LC-FC patch cord may be for you.

Polishing Type: PC, UPC, or APC

Fiber optic connectors are designed and polished to different shapes to minimize back reflection. According to these connector polish types, there are PC, UPC, and APC fiber patch cords. Typical back reflection levels are -30dB, -40dB, -50dB, and -60 dB.

Fiber Patch Lead Mode: Single Mode or Multimode

The mode of fiber patch cables indicates how light beams travel within the fiber. There are two fiber cable modes: single mode and multimode. Single-mode patch cords are yellow, the connector and protective sleeve are blue, and the transmission distance is long. The multimode patch cords are orange or aqua blue, the connector and protective sleeve are beige or black, and the transmission distance is short.

Number of Fiber Strands: Simplex or Duplex

According to the number of fiber strands, there are simplex and duplex fiber patch leads. The simplex fiber patch lead contains one strand of fiber with one simplex connector on each end. On the other hand, the duplex fiber patch lead consists of two strands of glass or plastic with one duplex connector.

Jacket Material of Fiber Patch Leads

Fiber patch leads have different jackets, including PVC, LSZH, OFNP, etc. They are the outer protective layer of an optical fiber cable to safeguard the fibers from abrasion, moisture, chemicals, and other external elements.


PVC is usually low-cost, flexible, fairly rugged, and a flame/oil-resistant material. So, fiber patch leads covered with PVC sheaths are widely used in wiring systems. In addition, PVC is recommended for indoor use.


LSZH patch cord sheath is made of low smoke zero halogen material. It is more rigid due to containing flame-retardant materials. In addition, it is free of halogenated materials. So, this fiber optic patch cord has low smoke and low toxicity. They are more suitable for public applications.


OFNP sheath refers to the American Fire Protection Commission standard, which is flame retardant. This material will automatically extinguish when away from the fire source. It is the most expensive and is suitable for large data centers.

Characteristics of Fiber Patch Leads

Stable quality

Fiber optic patch cords use high-quality optical fibers and connectors to ensure stable transmission quality.

Low Insertion Loss

A fiber-optic patch cord is constructed from a core with a high refractive index, surrounded by a coating with a low refractive index. Transparency of the core permits the transmission of optic signals with little loss over great distances. In addition, the coating’s lower refractive index causes light to be reflected toward the core, minimizing signal loss.

Relatively good adaptability to the environment

Fiber optic patch cords have a protective aramid yarn and outer jacket. They minimize physical damage to the core and coating. So, fiber patch leads can adapt to various environments, such as wind, rain, etc.

Connecting different devices

Fiber optic patch cords can connect optical fibers to different devices such as optical modules, switches, modems, etc. to achieve direct hardware connection.

Signal transmission

Fiber optic patch cords are a way to send and receive optical signals, ensuring stable data transmission.

Wide application

Fiber optic leads are widely used in applications such as telecom, datacom, and local area networks. It can be used in cable TV, communication, and optical test equipment.

Special Types of Fiber Patch Leads

Fiber patch leads are evolving to keep pace with the ever-increasing bandwidth needs. Some specially designed fiber patch cables emerge to fit different application needs.

Armored Fiber Patch Cord

Bwnfiber offers a massive selection of Armored fiber optic patch cables designed for harsh environments. These Armored Fiber Optic Patch Cords resist damage and environmental factors including rodents chewing on cable. Even with the steel armor, these cables remain flexible and bend randomly

MPO Patch Cord

MPO fiber patch leads

Bwnfiber provides high-density MTP and MPO Patch Cords products, including jumpers, fanouts, and pre-terminated solutions. MPO patch cord is a fiber optic patch cord that uses a multi-fiber connector called a multi-fiber push-on (MPO) connector. These fiber patch cords are used in high-density fiber optic networks, where many fiber cables need to be connected in a small space. MPO Patch Cords are commonly used in high-density data centers and telecommunications environments to provide fast and reliable connectivity for high-speed networking applications.
