SC to SC, OM3 Multimode Duplex, 50/125 Fiber Optic Patch Cables

SC to SC, OM3 Multimode Duplex, 50/125 Fiber Optic Patch Cables

The third type of multimode fiber cable, identified by an aqua blue jacket per industry standards, has a core size of 50μm. It is designed for Laser transmission in order to support 10G, 40G and 100G Ethernet Speeds. OM3 and OM4 are the current industry standard, but are quickly being outdated by the new OM5 fiber for its SWDM capabilities. An inconveiniece of this cable is there is no easy identifier between OM3 and OM4 fiber. Referred to as the "square connector", the SC has a push-pull coupling lock with a spring loaded ferrule. It was standardized into the telecom specs TIA-568-A and slowly grew in popularity because of its excellent performance. It is commonly used datacom/telecom point to point communication.

SC - UPC - Duplex

Referred to as the "square connector", the SC has a push-pull coupling lock with a spring loaded ferrule. It was standardized into the telecom specs TIA-568-A and slowly grew in popularity because of its excellent performance. It is commonly used datacom/telecom point to point communication.



This is also classified by its "ferrule polish" as an Ultra Physical Contact (UPC) Connector. This is regarding the connection point/shape of the ferrule tip. The tip is convex and an extended polishing method before attachment. The ends butt up against one another on a perpendicular plane. The main issue with the design is the tendency for back reflection with poor cleaving and repeat matings.

OM3 Fiber

OM3 Fiber

The third type of multimode fiber cable, identified by an aqua blue jacket per industry standards, has a core size of 50μm. It is designed for Laser transmission in order to support 10G, 40G and 100G Ethernet Speeds. OM3 and OM4 are the current industry standard, but are quickly being outdated by the new OM5 fiber for its SWDM capabilities. An inconveiniece of this cable is there is no easy identifier between OM3 and OM4 fiber.

Ultra Physical Contact Connector (UPC)

Ultra Physical Contact Connector (UPC)

The Ultra Physical Contact (UPC) Connector is a connection tip design for the Ferrule of the connector. The tip narrows, utilizing an extended polishing method which creates a finer fiber surface finish than Flat Connectors (not narrowed tip). This effectively provides a more reliable signal for digital TV and systems, where the UPC connector currently dominates the market. The design is said to have diminishing results after repeat mating and unmating of the ferrule tip. This repeat usage will increase the back reflection, lowering the quality of signal.
