MTRJ Singlemode & Multimode Duplex Ferrule Fiber Optical Connector

MTRJ connector is a type of fiber optic cable that has an endpoint similar to the RJ-45 connector endpoint found in Ethernet connections. MTRJ connectors are designed to snap into the Ethernet port of a computer, modem, or wireless router and provide that computer or network with extremely fast data transfer rates.

MTRJ connectors are usually designed for multi-mode optical fibers but can be used for single mode optical fibers as well. MTRJ connectors are approximately 2.45 mm x 4.4 mm in size and are standardized by the International Electrotechnical Commission.
