Optical fiber connectors are essential to the world of fiber optics. They allow fiber optic cables to be joined together and ensure light is transmitted seamlessly between them. It also protects the delicate glass fibers inside from damage. It contains mechanisms that align the cable cores precisely to minimize light loss during transmission. Its sturdy yet precisely engineered design makes long-haul connectivity possible.
The Structure of Fiber Optic Connectors
All fiber connectors have a similar internal structure to achieve optimal light transmission. Their components are carefully designed to work synergistically. The structure of an optical fiber connector typically consists of:
- Dust Cap
This is a small cap located at the connector tip. It provides vital end-face protection from contamination. The dust cap is snapped tightly over the ferrule to shield it.
- Housing
This forms the durable outer shell of the optical fiber connector that houses internal parts. It can be connected securely to the cable or panel.
- Ferrule
Ferrule is the cylindrical element within the housing where the optical fiber is fastened. Ferrules must align fibers in joining connectors to maximize light coupling. It is commonly made of ceramic, metal, and plastic.
- Stopper
Positioned behind the ferrule, the stopper helps prevent components from coming apart accidentally. Stoppers can regulate the ferrule’s depth within the housing. They center the ferrule and prevent it from sliding out of position.
- Riveting Ring
Found after the stopper, this riveting ring or crimp ring enables a tight yet reversible connection to the rest of the cable assembly. The riveting ring cinches the optical fiber connector firmly onto cables without the risk of loosening over time.
- Boot
As the name suggests, this outer sleeve covers and protects the more fragile internal components from incursion of moisture or particles. Its structure is flexible yet tight-fitting. The boot forms an environmental seal and strain relief interface.
Types of Fiber Optic Connectors
Understanding the various fiber optic connector types is key to choosing the best solution for different applications. Connectors below are the main categories handled in most projects:
- SC Connector
“SC” stands for “Square/Standard Connector.” It features compact dimensions and a quadrax-style latching mechanism. SC fiber optic connector is often used in backbone links and customer-premises equipment. It provides stable connections with low insertion losses.
- LC Connector
“LC” stands for “Lucent Connector.” This is one of the smallest connectors. It’s suitable for high-density patching and splitter equipment. LC fiber optic connector is extremely compact and supports both multi-mode and single-mode implementations.
- FC Connector
“FC” stands for “Ferrule Connector.” The FC fiber optic connector features a durable design with a threaded bayonet coupling. It is suitable for industrial environments and field-terminated links. Its screw-on connection delivers secure locking for rough outdoor deployments.
- ST Connector
“ST” stands for “Straight Tip.” ST fiber optic connector is an early telephony standard. It’s well-suited to multi-mode networks. It has a symmetric design enabling polarity maintenance during termination.
- MPO Connector
“MPO” stands for “Multi-fiber Push On.” MPO fiber optic connector features a high-count design. It is capable of deployments supporting up to 24 fibers in a single optical fiber connector. It is suitable for applications that require huge bandwidth, such as data centers.
- MTP Connector
“MTP” stands for “Multi-fiber Termination Push-on.” It is a type of MPO connector. All MTPs are MPOs but not all MPOs are MTPs. It provides pre-terminated solutions for applications with 12-24 fibers or more. MTP fiber optic connector enables inexpensive pre-fabricated cabling for backbone links.
- MDC Connector
“MDC” stands for “Miniature Duplex Connector.” This is a modular connector type. It can be rearranged and customized for uses demanding non-standard configurations. It is used where space matters. This type of optical fiber connector delivers fully flexible connectivity through its modular approach.
