High-Density LC Fiber Optic Connectors for Data Centers & Enterprise Networks
The iFiber Optix LC Series Fiber Optic Connectors are industry-leading solutions delivering unmatched performance, reliability, and compact design for modern high-speed data transmission. Featuring a small form factor that is half the size of standard SC connectors, LC connectors are the go-to choice for high-density fiber optic panels in data centers, telecom networks, and enterprise LAN environments.
From simplex and duplex to uniboot and fully custom configurations, iFiber Optix manufactures LC Series connectors for both singlemode and multimode applications — engineered to meet the highest industry standards for insertion loss, return loss, and long-term durability.
LC Series Fiber Optic Connectors
iFiber Optix LC Series connectors deliver a compact, push-pull interface optimized for high-density fiber deployments. Compatible with both singlemode (OS1/OS2) and multimode (OM1–OM5) fiber, these connectors are manufactured to exceed industry standards for insertion loss, return loss, and mechanical durability — available in simplex, duplex, uniboot, and fully custom configurations.
Key Features
- Small Form Factor Half the size of standard SC connectors, making LC the preferred solution for high-density patch panels and patch bays where every rack unit counts.
- High Performance Insertion loss as low as 0.15dB typical for singlemode and return loss exceeding 55dB PC — built for reliable, low-loss transmission on 10G, 40G, and 100G links.
- Push-Pull Ease of Installation Intuitive push-pull latch for quick, secure connections and clean disconnections without tools — reducing installation time and the risk of accidental disconnection in live environments.
- Versatile Fiber Compatibility Compatible with both singlemode (OS1/OS2) and multimode (OM1–OM5) fiber optic cables — a universal solution across virtually any fiber optic infrastructure.
- Custom Configurations Available Available in custom lengths, jacket types (plenum, LSZH), and connector polishes (PC, UPC, APC) to meet any project specification.
Types of LC Series Fiber Optic Connectors
Choose the LC configuration that best fits your fiber type, density requirements, and installation environment.
LC Simplex
Ideal for single-fiber singlemode applications requiring long-distance communication. Delivers low insertion loss and high return loss where every decibel of link budget counts.
LC Duplex
The most widely deployed LC configuration — perfect for two-fiber duplex transmission. Easy push-pull installation and removal, with high-density cabling without compromising optical performance.
LC Uniboot
Consolidates two fibers into a single boot, reducing cabling bulk and simplifying management in congested environments. Features reversible polarity — no rewiring needed for polarity changes.
Custom LC Connectors
Tailored to your exact specifications — custom fiber configurations, jacket types, connector polishes (PC, UPC, APC), and lengths for seamless integration into any network environment.
LC Series Technical Specifications
All iFiber Optix LC Series connectors are manufactured to exceed the following performance specifications for both singlemode and multimode applications.
| Specification | Singlemode | Multimode |
|---|---|---|
| Insertion Loss | ≤ 0.15dB typical | ≤ 0.20dB typical |
| Return Loss | ≥ 55dB PC | — |
| Durability | < 0.2dB change over rated cycles | < 0.2dB change over rated cycles |
| Operating Temperature | -40°C to +75°C | -40°C to +75°C |
| Fiber Compatibility | OS1 / OS2 (9/125µm) | OM1 / OM2 / OM3 / OM4 / OM5 |
| Polish Types | PC, UPC, APC | PC, UPC |
Example use case: OS2 singlemode LC duplex connector with APC polish deployed on a long-haul DWDM link — delivering ≥ 60dB return loss and < 0.15dB insertion loss over a 80km span.
Applications
LC connectors are deployed across virtually every segment of modern fiber infrastructure where density, speed, and reliable installation matter.
Data Centers
LC connectors dominate data center structured cabling — enabling maximum port density on patch panels and switches while maintaining clean, manageable cable runs in high-velocity environments.
Telecommunications
Support carrier-grade telecom networks with superior performance in long-haul, MAN, FTTH, and FTTB deployments where signal integrity over distance is critical.
Enterprise Networks
Compact size and tool-free installation make LC the preferred connector for enterprise LAN, WAN, and backbone cabling in office buildings, campuses, and multi-tenant facilities.
Broadband Networks
Widely deployed in broadband infrastructure supporting both residential and commercial last-mile fiber deployments at scale.

How to Choose the Right LC Connector
Selecting the correct LC connector ensures optimal optical performance and compatibility with your existing hardware and fiber plant.
Select Fiber Type
Singlemode (OS1/OS2) pairs with UPC or APC LC connectors for long-distance links. Multimode (OM1–OM5) typically uses PC or UPC connectors for high-bandwidth short-reach applications.
Choose Configuration
Most modern SFP and SFP+ transceivers require LC duplex. Use simplex for single-fiber applications or uniboot where cable management and polarity flexibility are priorities.
Determine Polish Type
APC polish (angled) delivers the lowest return loss and is preferred for analog/DWDM systems. UPC is standard for most digital links. PC is common in legacy installations.
