Fiber Optic Cable Connector Specifications and Prices

Fiber optic connectors come in various types such as LC, SC, ST, and MTP, with specifications including polish type, ferrule material, and insertion loss, and prices typically range from $1 to $20 per connector depending on type and quality. Connector Types and FeaturesLC (Lucent Connector): Small form factor, push-pull design, uses precision PC polished zirconia ceramic ferrules, ideal for high-density applications, insertion loss typically 0. 1–0.

5 dB.

S

C (Square Connector): Push-on design, widely used in telecom and data networks, available in PC, UPC, and APC polish types.

S

T (Straight Tip): Twist-on connector, commonly used in legacy networks, spring-loaded ferrule for minimal signal loss. MTP/MPO: Multi-fiber push-on/pull-off connectors, suitable for high-density cabling, often used in data centers. Field-terminable connectors: Allow on-site installation without consumables, e.g., Corning UniCam, with rapid termination and low insertion loss.

Technical Specifications

Polish Types: PC (Physical Contact), UPC (Ultra Physical Contact), APC (Angled Physical Contact) to reduce reflection and insertion loss. Ferrule Materials: Ceramic, stainless steel, plastic, or tungsten carbide, ensuring precise fiber alignment. Fiber Compatibility: Singlemode (SM) and multimode (MM, OM1–OM4), with core diameters from 3 µm to 1000 µm.

Insertion Loss: Typically 0. 1 dB (typical) to 0. 5 dB (maximum) per connector pair.

Durability: Many connectors are spring-loaded to maintain fiber contact and minimize signal loss; MIL-SPEC versions are available for rugged environments.

Pricing Overview

Standard connectors: LC, SC, and ST connectors generally range from $1 to $5 per unit for bulk purchases. High-performance or field-terminable connectors: Corning UniCam or MTP connectors can cost $10–$20 per unit, depending on fiber type and polish. Specialized or military-grade connectors: Prices vary significantly based on specifications and environmental ratings, often requiring direct consultation with suppliers.
