Introduction: Duplex Fiber Optic Adaptors, also named as fiber adapter or fiber coupler, is a special connector designed to mate or connect two ends of a fiber optic cable with high precision. Fiber adapters are widely used in optical distribution frame (ODF), optical fiber communications equipment, measuring appliance and so on. According to the types of fiber optic connectors that fiber adapters are connected, there are common adapters such SC, FC, ST, LC and MTP/MPO adapter etc., also available in singlemode or multimode. Application: Duplex Fiber Optic Adaptors are used in fiber optic connection, the typical use is to provide a cable to cable fiber connection. people sometimes also name them to be mating sleeves and hybrid adapters, mating sleeves means this fiber optic adapter is used to connect the same type fiber optic connectors, while hybrid adapters are the fiber optic adapter types used to connect different kinds of fiber optic connectors • FTTH Termination box • In-House termination box • Optical Distribution Frame (ODF) Operation Features: Duplex Fiber Optic Adaptors is a perfect solution for provide a cable to cable fiber connection. It is widely used where needed for a quick connection, providing a quick assembly and stable performance with the following features • SC, FC, ST, LC and MTP/MPO adapters are available • Simplex, duplex or quad type • Available in Singlemode or Multimode • High precise ceramic sleeve • Low insertion loss • Repeatability, interchangeability, stability • Shutters open and close automatically • With or without flange for optional • Reliable durable and superior optical performance Mechanical Performance Test compliance: Adapter types: SC, FC, ST and LC adapters are available Fiber type: SM G652D, 657A, 657B and MM Polishing Type: UPC or APC Insert loss: ≤0.2dB Return loss: UPC≥50dB, APC≥60dB Durability: ≤0.2dB after 1000times Operation Temperature: -40 to +60°C Storage Temperature: -40 to +70°C
