Fiber Optic Cable LC Connector

Key Features

High-Density LC Form Factor – Compact 1.25 mm ferrule design maximizes fiber port density in racks and ODFs.

Singlemode & Multimode Options – Supports 9/125 μm and OM2/OM3/OM4/OM5 fibers for a wide range of applications.

UPC & APC End-Face Available – Choose UPC for general links or APC for low-reflection, high-return-loss applications.

Low Insertion Loss, Stable Performance – Precision zirconia ferrule ensures accurate fiber alignment and low optical loss.

Reliable Latch & Housing – Push-pull locking mechanism provides secure mating and easy handling in dense panels.

International Standard Compliance – Designed to meet IEC/TIA/GR-326 requirements when used in qualified assemblies.

100% Tested Before Shipment – Each connector is checked for geometry, insertion loss, and return loss to ensure consistency.

Ordering Information
DIMI fiber optic cable LC connectors are available in simplex or duplex versions, for singlemode or multimode fibers, with UPC or APC polish. Different boot sizes (0.9 mm / 2.0 mm / 3.0 mm), housing colors, and logo printing can be customized. Pre-terminated LC patch cords, pigtails, and harness cables can also be supplied according to your project and panel layout requirements.

FAQ

Q1: What is the advantage of an LC connector compared with an SC connector?
A1: LC connectors use a smaller 1.25 mm ferrule and compact latch design, allowing much higher port density on patch panels and ODFs than SC connectors. This helps save rack space in data centers and telecom rooms.

Q2: When should I choose LC UPC vs LC APC?
A2: LC UPC is recommended for most standard singlemode and multimode data links. LC APC is preferred in applications that are highly sensitive to back reflection, such as FTTx, RF over fiber, or long-haul singlemode links.

Q3: Can DIMI provide LC connectors as complete patch cords and pigtails?
A3: Yes. DIMI can deliver complete LC patch cords and pigtails with customized length, fiber type, jacket material, labeling, and packaging to match your ODF and data center deployment.
