CS-LC Fiber Patch Cord

High-Density Hybrid Solution for 400G Migration

Overview

As data centers evolve to meet the demands of AI, machine learning, and hyperscale computing, the transition to 400G is no longer optional—it is inevitable. However, legacy infrastructure often struggles to keep pace with the density requirements of modern transceivers like QSFP-DD and OSFP.

The CS-LC Fiber Patch Cord serves as the critical bridge between next-generation high-speed equipment and existing structured cabling. By combining a compact CS connector on one end with a standard LC connector on the other, this patch cord enables seamless interoperability, optimizes panel space, and future-proofs your network investment.

CS-LC cables are one of the most common types of fiber optic patch cords used in data centers and telecom networks.

Key Features

1. 40% Smaller Connector Footprint
The CS connector is engineered specifically for high-density applications. It occupies 40% less space than a standard duplex LC connector. This reduction allows for higher port counts on switch faceplates and patching fields, maximizing the utility of your rack space.

2. Seamless 400G Equipment Integration
Designed for next-gen 400G optics (QSFP-DD/OSFP), the CS interface ensures direct compatibility with modern transceivers. This patch cord allows you to connect these high-speed switches to your existing LC-based panels or legacy devices without the need for expensive conversion cables or “break-out” cassettes.

3. Enhanced Usability with Push-Pull Design
High-density environments often make cable management difficult. Our CS-LC cords feature a tool-less push-pull boot. The integrated tab mechanism allows technicians to easily engage and disengage the connector in tight spaces, preventing damage to adjacent connectors and reducing installation time.

4. Superior Signal Integrity
Built with precision 1.25mm ceramic ferrules, the cord ensures optimal core alignment and physical contact.

• Low Insertion Loss: ≤ 0.3 dB guarantees high light transmission and system power budgets.

• Backward Compatibility: The LC end works perfectly with all standard LC adapters and ports.

5. Robust & Flexible Construction
Utilizing high-quality LSZH (Low Smoke Zero Halogen) jackets and bend-insensitive fiber (G.657.A1), the cable maintains signal integrity even under stress, while ensuring safety and compliance in data center environments.

Applications

CS-LC cables are widely used in high-density data centers, telecom networks, and FTTH systems. They are part of the fiber optic patch cord family used to provide flexible optical connections between network equipment.
