Fiber optic model SCPC

SCPC fiber optic cables are single-mode patch cords with SC connectors on both ends, commonly used for high-density data center and telecommunication applications.

Overview

SCPC (SC to PC) fiber optic patch cords are single-mode cables equipped with SC connectors at both ends, designed for reliable optical signal transmission in telecommunications, CATV, and data networks . They are often available in duplex configurations, meaning two fibers are bundled together for simultaneous bidirectional communication . These cords are also referred to as jumper cables and are pre-assembled for easy deployment.

Connector Types and Polish

The SCPC designation indicates SC (Subscriber Connector) type connectors with PC (Physical Contact) polish. The PC polish features a slightly curved end face to reduce air gaps and minimize insertion loss, typically achieving a return loss of around -40 dB . Variants include UPC (Ultra Physical Contact) for improved return loss (_{-50 dB) and APC (Angled Physical Contact) for high-frequency applications with minimal back-reflection (}-60 dB), .

Construction and Specifications

• Single-mode fiber: 9/125 µm core/cladding diameter for long-distance, low-loss transmission .
• Duplex or simplex: Duplex cords contain two fibers for bidirectional communication .
• Armored or standard jacket: Armored versions provide extra protection against bending and mechanical stress, with a recommended minimum bend radius of 15 times the cable diameter to prevent micro-bending losses .
• Compliance: Typically adheres to IEC, TIA/EIA, and RoHS standards for optical performance and environmental safety .
• Lengths: Available in standard lengths (1 m, 2 m, 5 m, etc.) with tolerances depending on the manufacturer .

Applications

SCPC fiber optic patch cords are widely used in:

• Data centers for high-density connectivity .
• Telecommunications networks for linking optical equipment.
• CATV and RF systems where low back-reflection is critical, especially with APC connectors .
• Indoor and outdoor installations, depending on jacket type and environmental rating .

Key Considerations

• Ensure the correct connector polish (PC, UPC, APC) for your application to optimize signal quality.
• Maintain the minimum bend radius to prevent signal loss, especially for armored cords .
• Verify single-mode vs. multi-mode compatibility with your network equipment. SCPC fiber optic patch cords provide a reliable, standardized solution for connecting optical devices, ensuring low insertion loss, high return loss, and durability in both enterprise and telecom environments .
