Overview
This lecture covers the main fiber optic connector types, their names, usage, and locking mechanisms, with emphasis on practical differences and identification.
SC Connector (Subscriber Connector)
- SC stands for Subscriber Connector, also known as Square Connector or Standard Connector.
- It has a square shape and locks into place by pushing in; to remove, pull to unlock.
- SC connectors are common in data centers for fiber optic connections.
- Usually used in pairs: one for transmit, one for receive.
LC Connector (Local Connector)
- LC stands for Local Connector, also known as Lucent or Little Connector.
- LC is smaller than SC and uses a locking clip on top.
- To remove the LC connector, push down the clip before pulling out.
- Often used in pairs for transmit and receive, allowing simultaneous connection.
ST Connector (Straight Tip)
- ST stands for Straight Tip and uses a bayonet-style lock: push in, twist to lock.
- Removal is done by twisting in the opposite direction before pulling out.
- Commonly used where many cables are present to avoid accidental disconnection.
- Features a protective ferrule around the fiber.
MPO/MTP Connector (Multifiber Push-On)
- MPO stands for Multifiber Push-On; sometimes called MTP (by Corning).
- MPO/MTP connectors house 12 individual fibers in a single compact connector.
- Uses a locking mechanism similar to the SC: push in to lock, pull to unlock.
- Designed for high-density situations where space-saving is needed.
Key Terms & Definitions
- Fiber Connector — Device used to join optical fibers and enable signal transmission.
- SC Connector — Subscriber Connector; square-shaped, snap-in lock.
- LC Connector — Local, Lucent, or Little Connector; small size, locking clip.
- ST Connector — Straight Tip; uses a bayonet twist-lock mechanism.
- MPO/MTP Connector — Multifiber Push-On; connects multiple fibers in one compact unit.
Action Items / Next Steps
- Review visual identifiers for each connector type.
- Practice connecting and disconnecting each fiber optic connector to understand locking mechanisms.
