Types and Losses of Fiber Optic Connectors

Fiber and communications infrastructure knowledge brief Published 10 Dec 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.

Fiber optic connectors come in various types such as LC, SC, FC, ST, and MPO/MTP, with insertion loss typically ranging from 0. 1–0. 5 dB and return loss varying by polish type (UPC or APC).

Common Fiber Optic Connector Types1.

L

C (Lucent Connector)Small form factor with a 1. 25 mm ferrule, ideal for high-density applications. Uses a latch mechanism similar to an RJ45 plug.

Typical insertion loss: 50 dB (UPC) or >55 dB (APC). Commonly used in single-mode networks, 10G/40G/100G links, and data centers. 2.

S

C (Subscriber Connector)Square-shaped with a 2. 5 mm ferrule and push-pull coupling. Durable and widely used in FTTH and telecom networks.

Available in UPC and AP

C polishing types. Typical insertion loss: 0. 2–0.

5 dB; return loss: moderate for UPC, high for APC. 3.

F

C (Ferrule Connector)Screw-on type, providing stable connections for high-vibration environments. Often used in test equipment and long-haul networks.

Supports UPC and AP

C polishing. 4.

S

T (Straight Tip)Bayonet-style connector with 2. 5 mm ferrule. Common in legacy multimode networks and campus installations.

Insertion loss: ~0. 3 dB; return loss depends on polish type. 5.

MPO/MTP (Multi-Fiber Push-On / Multi-Fiber Termination Push-On)Designed for multi-fiber environments (12, 24, or more fibers). Higher insertion loss due to alignment complexity, but premium low-loss MPOs can achieve
