Multimode fiber connector types9/15/2023 LC connectors are used with single-mode and multimode fiber-optic cables. From a design perspective, it is recommended to use a loss margin of 0.5 dB or the vendor recommendation for ST connectors. The typical insertion loss for matched ST connectors is 0.25 dB. They have ceramic ferrules and are rated for 500 mating cycles. ST connectors are constructed with a metal housing and are nickel-plated. ST connectors come in two versions: ST and ST-II. It can be inserted into and removed from a fiber-optic cable both quickly and easily. The ST Connector is a keyed bayonet connector and is used for both multimode and single-mode fiber-optic cables. From a design perspective, it is recommended to use a loss margin of 0.5 dB or the vendor recommendation for SC connectors. Typical matched SC connectors are rated for 1000 mating cycles and have an insertion loss of 0.25 dB. An SC connector is a push-on, pull-off connector with a locking tab. SC connectors provide for accurate alignment via their ceramic ferrules. They offer low cost, simplicity, and durability. SC connectors are used with single-mode and multimode fiber-optic cables. UPC, or ultra physical contact, is a dome shaped polish type that also has minimum fiber loss, second only to APC. This is the most optimum polish type for minimum signal loss. APC, or angled polish connectors, have an angled polish as the name suggests. You may notice that underneath single mode, there are two different acronyms, APC and UPC. MTP/MPO type connector cables aren't listed here simply because they are a bit newer and have a different build than older fiber connector types. Here is a helpful fiber optic connector types chart for your reference. Manufacturers and distributors are more likely to have equipment to accommodate SC and ST style connectors than any other connector style.įiber Savvy stocks your fiber connector needs with, LC Connectors, SC Connectors, ST Connectors and MTP/MPO Connectors. There are a number of connector styles on the market including LC, FC, MTP/MPO, and SC Connectors, which are the most popular connectors. But depending on the project field assembly may be preferred. Some manufacturers will assemble the connectors onto the fiber cable before distributing the cable, making it a quicker and easier install. Of the many different fiber connector types, connectors for both glass fiber cable and plastic fiber optic cable are available. High quality connectors prevent misalignment and air gaps between fibers, minimizing the reflection or loss of signal. Connectors match up the fibers from the cables so they are aligned and allow light to pass through and continue signal transmission. The fiber optic connector terminates the end of a fiber optic cable and offers quicker connection and disconnection compared to splicing. Fiber Connector and Fiber Connector Types
