Fiber optic joints or terminations are made two ways: 1) connectors that mate two fibers to create a temporary joint, patch between two cables and/or connect the fiber to a piece of network gear or 2) splices which create a permanent joint between the two fibers. Either. Fiber connectors are convenient for connections which need to be released more often. Unlike fiber splicing, which is permanent, connectors allow for easy connection and disconnection of cables, making them ideal for maintenance and flexibility in. Thorlabs' mating sleeves are compatible with industry-standard connectors such as FC/PC, FC/APC, SMA, ST, LC, and SC.
