Fiber Optic Connectors

Fiber Optic Connector is an important component used in fiber optic network. It is also the key part used in fiber optic patch cord and fiber optic pigtail.

SINO OPTIC manufactures various types of fiber optic connectors, including both standard and non-standard types. We supply fiber optic connectors with the types of: SC connector, LC connector, ST connector, FC connector, E2000 connector, MU connector, MT-RJ connector, and MPO/MTP connector etc.

Both single mode and multimode fiber optic connectors are available in SINO OPTIC.
Single mode fiber optic connectors are with PC, UPC or APC polish, while Multimode fiber optic connectors are only with PC or UPC polish.

Judging from the out looking, Multimode connectors are usually with black boot or beige color, Single mode PC and UPC ones are usually with blue or black color, Single mode APC is with green color.

Insertion loss is the most important technical data for fiber optic connectors. The smaller the better. APC insertion loss is smaller than UPC, UPC is smaller than PC.
