Fiber Optic Cable Square Connector

Fiber and communications infrastructure knowledge brief Published 11 Aug 2024

Prepared for preliminary research by the ROGER FIBRE knowledge desk. Confirm optical interfaces, port or core capacity, electrical input and output, enclosure protection, thermal design and installation limits against current standards and product documentation.

A fiber optic cable square connector, commonly called an SC connector, is a push-pull fiber optic connector with a square-shaped body and a 2. 5 mm ferrule used to join optical fibers reliably and efficiently.

Overview

The S

C connector, also known as Subscriber Connector, Square Connector, or Stick-and-Click connector, is widely used in optical networks such as FTTH (Fiber to the Home), FTTx, and telecom access networks. Its square-shaped body makes it compact and easy to handle, while the push-pull latching mechanism allows for quick and secure connections and disconnections without twisting or turning.

Key Features

Ferrule Size: SC connectors use a 2. 5 mm ceramic ferrule, which aligns the optical fibers precisely to minimize signal loss and reflection. Connection Type: Push-pull design ensures a firm connection and easy removal, making it installer-friendly.

Duplex and Simplex Options: SC connectors are available in simplex (single fiber) and duplex (two fibers for full-duplex communication) configurations. Compatibility: Suitable for both single-mode and multimode fibers, providing flexibility across different network types. Durability: The ceramic ferrule and robust housing make SC connectors reliable for indoor and controlled outdoor environments, though additional protection may be needed for harsh outdoor conditions.

ApplicationsSC connectors are commonly used in: FTTH and FTTx networks for residential and commercial fiber access. Telecom and data center networks where reliable, repeatable connections are required. Passive optical networks (PONs), including GPON and RF video distribution, where low return loss is critical.

Advantages

Easy to install and remove due to the push-pull mechanism. Provides precise fiber alignment for low insertion loss. Standardized design ensures compatibility with patch panels, transceivers, and adapters.

Duplex configuration supports full-duplex communication efficiently. In summary, a fiber optic cable square connector (SC connector) is a standardized, reliable, and widely used connector type that simplifies fiber optic network installation and maintenance while ensuring high-performance optical signal transmission.
