Fiber Optic Patch Cable: A fiber optic patch cable is created by fixing fiber optic connectors to both ends of a fiber optic cable through a specific process, resulting in a cable with fiber optic connectors at both ends and a fiber optic cable in between.
Classification by Mode: Divided into Single-mode Fiber and Multi-mode Fiber
Single-mode Fiber: Typically, single-mode fiber patch cables are yellow in color, with blue connectors and protective jackets. They are capable of transmitting signals over longer distances.
Multimode Fiber: OM1 and OM2 patch cables are typically orange, while OM3 and OM4 patch cables are aqua. Under gigabit rates, OM1 and OM2 have a transmission distance of 550 meters, while under 10-gigabit rates, OM3 has a transmission distance of 300 meters, and OM4 has a transmission distance of 400 meters. Connectors and protective jackets are usually beige or black.
Classified by connector types:
The commonly used types of optical fiber patch cables include LC patch cables, SC patch cables, FC patch cables, and ST patch cables.
The commonly used types of optical fiber patch cables include LC patch cables, SC patch cables, FC patch cables, and ST patch cables.
①LC Optical Fiber Patch Cable: It is made with a convenient modular jack (RJ) locking mechanism, used for connecting SFP optical modules, commonly used in routers.
②SC Optical Fiber Patch Cable: Its shell is rectangular, secured with a plug-and-latch mechanism without requiring rotation. It is used for connecting GBIC optical modules, most commonly used in routers and switches, known for its low cost and minimal insertion loss fluctuations.
③FC Optical Fiber Patch Cable: The external protective sheath is made of metal, secured with screw-on connectors, widely used in patch panels. It features strong fastening and dust resistance.
④ST Optical Fiber Patch Cable: Its shell is circular, secured with screw-on connectors, with the fiber core exposed. After insertion, it is rotated half a turn to secure it with a latch. It is often used in fiber patch panels.
Classified by application:
① MTP/MPO Fiber Optic Patch Cables: Commonly used in environments requiring high-density integrated fiber optic circuits during cabling processes. Their advantages include a simple push-pull locking structure for easy installation and removal, saving time and cost, and maximizing lifespan.
③ Conventional Fiber Optic Patch Cables: Compared to MTP/MPO and armored fiber optic patch cables, conventional ones offer strong scalability, compatibility, and interoperability, effectively reducing costs.
