Fiber optic connector types
The connector can be supplied as a pre-assembled one-piece connector or as connector kits.
LC stands for Lucent Connector. LC connector is push and pull type. The LC fiber connector has good performance for single mode and are widely used in fiber optic patch cord.
SC Optical connector offers excellent packing density, and its push-pull design resists fiber end face contact damage.
ST fiber connectors are a good choice for easy field installations; ST connector is metal structure. it is a push-pull type, not screw type. Ferrule of ST fiber optic connector is exposed outside..
FC Optical connector has a floating ferrule that provides good mechanical isolation; Same as SC fiber optic connector, FC connector is also invented by NTT Company. FC has metal housing, screw structure, FC connector and SC connector have the same ferrule and sleeves.
MTRJ optical Connector
MT-RJ optical connector was developed based on MT connector which is commonly used for data transmission; it has a RJ-45 style structure, so called MT-RJ. MTRJ connector is with duplex fiber channel inside one single connector, the space between the two channels is 0.75mm.
MU Fiber Optic Connector
SMA Fiber Optic Connector
DIN Fiber Optic Connector
Optical connector can be supplied as a pre-assembled one-piece connector or as connector kits.
Optical connectors are installed on fiber patch cable ends to provide cable attachment to a receiver, transmitter or other cable. Optical connectors can enable quicker connection and disconnection. All connectors have 4 basic components: connector body, ferrule, cable and coupling device.
Low insertion loss and back reflection loss
Free-floating ceramic ferrule
UL-rated plastic housing and boot
Boots in a variety of colors
High precision alignment
