MTRJ Adapter, ceramic alignment sleeve, black for 2 cores MT-RJ fiber optic patch cord pigtails

MTRJ Fiber optic adapters are mainly used for connecting and fixing MTRJ fiber optic connectors, allowing optical signals to be transmitted with minimal insertion loss. The connection method of MT-RJ adapter is different from that of SC adapter. SC connector uses ceramic sleeve to precisely align the plug of the connector, while MT-RJ adapter and MPO adapter use two guide holes with a diameter of 0.7mm on the left and right of the MT-RJ connector plug end face and guide pins (also known as PIN pins) for precise connection. Therefore, MT-RJ adapter and MPO adapter are not classified as single or multi-mode. MT-RJ adapters and MPO adapters are widely used in communication system base stations, optical distribution frames (ODFs) in building computer rooms, communication equipment, and various testing instruments.
