SC Series Fiber Optic Connectors
The iFiber Optix SC Series Fiber Optic Connectors are engineered to provide secure, efficient, and high-performance connections across the full spectrum of contemporary fiber optic networks. Featuring a push-pull latching mechanism for quick, tool-free installation and a Physical Contact (PC) polish for low insertion loss and minimal back reflection, SC connectors remain one of the most widely deployed fiber optic connector types in the world.
Compliant with ANSI, IEC, TIA/EIA, and RoHS standards and available for both singlemode and multimode fiber, iFiber Optix SC Series connectors deliver the reliability, durability, and optical precision that telecommunications networks, data centers, and enterprise infrastructures demand.
SC Series Fiber Optic Connectors
The SC (Subscriber Connector) features a robust push-pull latching body that snaps securely into place and releases cleanly with a single motion — no threading, no tools, no accidental disconnections. With a 2.5mm ceramic ferrule in Physical Contact (PC) configuration, SC connectors deliver low insertion loss, high return loss, and consistent optical alignment across thousands of mating cycles. Available for OS1/OS2 singlemode and OM1–OM4 multimode fiber applications.

- Push-Pull Latching Mechanism The SC connector's push-pull latch provides quick, positive insertion and clean single-motion removal — no threading required. This design eliminates the risk of accidental disconnection while dramatically reducing installation and maintenance time compared to threaded connectors.
- Physical Contact (PC) Polish The PC ferrule end-face ensures direct glass-to-glass contact, delivering low insertion loss and reduced back reflection for reliable, high-quality signal transmission across both singlemode and multimode fiber applications.
- Low Insertion Loss Insertion loss of ≤ 0.15dB typical for singlemode and ≤ 0.20dB typical for multimode, maintaining efficient signal transmission and maximizing available link budget across the full fiber span.
- High Return Loss Return loss of ≥ 55dB PC for singlemode connections, minimizing reflected optical power and protecting upstream transmitters and transceivers from back-reflection interference.
- High Durability & Reliability Durability rated at <0.1dB change over the full rated mating cycle count, with a wide operating temperature range of -40°C to +75°C — designed for long-term performance across diverse environmental conditions.
- Industry Standards Compliance Fully compliant with ANSI, IEC, TIA/EIA, and RoHS standards, ensuring compatibility with existing infrastructure, safety in regulated environments, and acceptance across international network deployments.

Applications
SC connectors are among the most universally deployed fiber optic connector types — found across telecommunications, enterprise, and data center infrastructure worldwide.
Telecommunications Networks
Ideal for high-speed data transmission in telecom central offices, distribution frames, and long-haul fiber infrastructure — where the SC's large body and positive latch make it easy to manage in dense patch environments.
Data Centers
Suitable for high-density fiber optic panel connections in data centers, supporting efficient singlemode and multimode patch cord management across server rows, top-of-rack switches, and core distribution frames.
Enterprise Networks
Perfect for internal LAN, WAN, and backbone cabling in office buildings and campuses — where the SC's ease of installation simplifies moves, adds, and changes in structured cabling environments.
Fiber to the Home
Widely used in FTTH and FTTB optical network terminals (ONT) and distribution points, providing reliable singlemode connections for residential and commercial last-mile fiber deployments.
Broadcast & AV Systems
SC connectors are a common choice in broadcast and professional AV fiber infrastructure — where singlemode fiber carries video and control signals over longer campus or facility distances.
Legacy Infrastructure
SC remains one of the most prevalent installed connector types globally. iFiber Optix SC Series connectors provide fully compatible replacements and extensions for existing SC-based infrastructure without requiring costly adapter panels.
How to Choose the Right SC Connector
SC connectors are available for a range of fiber types and applications — use this guide to confirm the correct configuration for your deployment.
Select Fiber Type
OS1/OS2 singlemode for long-distance or high-bandwidth backbone and telecom links. OM1–OM4 multimode for shorter-reach connections within buildings or data center rows where SC is already the installed connector type.
Confirm Simplex or Duplex
SC connectors are available in both simplex (single fiber) and duplex (two-fiber side-by-side) configurations. Most transceiver equipment using SC interfaces requires duplex — verify your equipment specifications before ordering.
PC vs. UPC vs. APC
SC/PC is the standard configuration for most digital applications. SC/UPC provides slightly improved return loss for high-performance digital links. SC/APC (green, angled ferrule) is required for analog, CATV, and DWDM systems where back reflection must be virtually eliminated.
SC vs. LC for New Deployments
For new high-density installations, LC connectors offer a smaller footprint and higher port density. SC remains the correct choice when matching existing SC infrastructure, when larger connector bodies aid technician handling, or when equipment specifies SC interfaces.
