Lc4 core optical module

An LC4 core optical module is a high-speed fiber optic transceiver module that uses four parallel optical lanes with LC duplex interfaces, typically supporting 100Gbps data transmission for short- to medium-range applications.

Overview

The LC4 core optical module is designed for high-density, high-speed fiber optic networks, commonly deployed in data centers, enterprise networks, and server interconnects. It uses four optical lanes, each capable of transmitting 25Gbps, resulting in a total bandwidth of 100Gbps. The module often employs LC duplex connectors, which are compact and suitable for dense cabling environments .

Key Features

• Transmission Technology: Uses Short-Wavelength Division Multiplexing (SWDM) or PAM4 modulation to transmit multiple signals over a single multimode or single-mode fiber .
• Interface Type: Typically LC duplex, allowing easy integration with standard fiber patch panels and cabling infrastructure .
• Wavelengths: Operates across multiple wavelengths (e.g., 850nm, 880nm, 910nm, 940nm for multimode; 1310nm for single-mode) to support parallel data lanes .
• Transmission Distance: Supports short- to medium-range connections, up to 100 meters on OM4 multimode fiber or up to 500 meters on single-mode fiber .
• Applications: Ideal for intra-data center interconnects, fiber-to-the-server connections, and high-density computing environments requiring space-efficient cabling .

Deployment Considerations

• High-Density Environments: LC4 modules are suitable for leaf-spine architectures and high-density racks due to their compact LC interface .
• Compatibility: Works with standard LC patch cables, adapters, and cassettes, ensuring interoperability with existing fiber infrastructure .
• Performance: Optimized for low power consumption and minimal signal loss, making them effective for mission-critical and high-speed networking scenarios .

Summary

The LC4 core optical module is a versatile, high-performance transceiver that leverages four parallel optical lanes and LC duplex connectors to deliver 100Gbps bandwidth over short to medium distances. It is widely used in data centers and enterprise networks where high-speed, reliable, and space-efficient fiber connections are essential .
