LC/APC Connector Series for High-Performance Fiber Optic Connections
The iFiber Optix LC/APC Connector Series delivers high-performance, ultra-low-loss fiber optic connections for applications requiring minimal back reflection and superior signal integrity. Featuring an angled physical contact (APC) polish at 8 degrees, these connectors are purpose-built for singlemode fiber — ensuring precision, stability, and long-term reliability across telecom networks, FTTH deployments, and high-density data center environments.
From standard configurations to fully custom-engineered solutions, iFiber Optix LC/APC connectors are manufactured to exceed the highest industry standards — delivering consistent performance in even the most demanding high-bandwidth environments.
LC/APC Connector Series
The LC/APC connector combines the compact, high-density form factor of the LC interface with an angled 8-degree APC polish — minimizing back reflection and maintaining signal integrity in networks that demand the lowest possible noise floor. Optimized for singlemode fiber, these connectors are the standard choice for FTTH, carrier telecom, and enterprise backbone infrastructure where performance over distance is non-negotiable.

- Ultra-Low Back Reflection The 8-degree APC polish minimizes reflected light back into the fiber, ensuring stable, interference-free signal transmission — essential for analog, DWDM, and CATV systems that are sensitive to return loss.
- Low Insertion Loss LC/APC connectors deliver insertion loss of <0.3dB, reducing signal degradation and ensuring reliable network performance across long-distance singlemode fiber spans.
- Compact High-Density Design The LC form factor is half the size of SC connectors — ideal for high-density patch panels, telecom rooms, and data centers where space-saving solutions are required without sacrificing optical performance.
- Singlemode Fiber Optimized Engineered specifically for singlemode OS1/OS2 fiber, supporting long-distance, high-bandwidth applications up to 10km and beyond in telecom, FTTH, and enterprise backbone environments.
- Durable Long-Term Construction Built with premium materials to withstand frequent mating cycles and challenging environmental conditions, ensuring consistent performance and long service life in production deployments.

Applications
LC/APC connectors are essential across industries and network environments where low back reflection and stable singlemode performance are required.
Telecommunication Networks
Ensure high-quality, stable connections in metro networks and backhaul links for long-distance carrier communication where signal integrity is mission-critical.
Fiber to the Home
Widely deployed in FTTH and FTTB installations, providing reliable high-speed internet to homes and businesses with minimal signal degradation over the last mile.
Data Centers
Enable high-density singlemode installations while maintaining superior signal quality for inter-server and inter-switch connections in hyperscale and enterprise data centers.
Enterprise Networks
Support low-latency, high-bandwidth inter-office and inter-building backbone connections within enterprise infrastructures — seamlessly integrating with both modern and legacy systems.
Medical & Industrial
Deliver reliable, precise communication in medical facilities and industrial environments that demand high-performance fiber optic connections under environmental stress.
DWDM & Analog Systems
APC polishing is the required standard for DWDM, CATV, and analog signal networks — where even minimal back reflection causes measurable noise and signal degradation.

How to Choose the Right LC/APC Connector
Selecting the right LC/APC connector ensures optimal performance and full compatibility with your fiber plant and network equipment.
Network Type & Distance
LC/APC connectors are ideal for telecom, FTTH, and data center networks requiring long-distance, high-bandwidth singlemode communication. Confirm your link budget and span requirements before specifying connector grade.
Connector Compatibility
Verify your transceivers, patch panels, and active equipment support LC/APC interfaces. APC connectors use a green color code — never mate APC with UPC connectors, as this causes performance degradation and potential physical damage.
Density vs. Legacy Systems
Use LC/APC for high-density new deployments where space is at a premium. If integrating with legacy SC/APC infrastructure, plan for appropriate hybrid adapters to maintain APC-to-APC mating throughout the link.
Environmental Conditions
For outdoor, industrial, or harsh-environment deployments, select ruggedized or armored LC/APC assemblies rated for the expected temperature range, moisture exposure, and mechanical stress of your installation.
