4CH Lan-WDM Spec

4CH LAN + WDM (Wavelength Division Multiplexing) is an optical communication solution that combines Local Area Network (LAN) and WDM technologies. It enables high-bandwidth, high-efficiency data transmission by transmitting multiple wavelength channels (typically four) in the same optical fibre, and is widely used in data centres, enterprise networks and telecom infrastructures.

Feature

Wavelength Division Multiplexing (WDM):

The use of different wavelengths (e.g. 1310nm, 1490nm, 1550nm, etc.) to transmit multiple signals in the same fibre.

4-channel design:

Supports 4 independent wavelength channels, suitable for medium-sized network requirements.

High compatibility:

Compatible with existing fibre infrastructure, no need for large-scale modifications.

Low power consumption:

Highly efficient optical module design reduces energy consumption.

Applications

Data Centre:

Server Interconnect: for high-speed connections between servers and switches.

Storage Area Network (SAN): supports high-capacity data storage and transmission.

Enterprise Network:

LAN Extension: Enables high-bandwidth, low-latency network connectivity within the enterprise.

Multi-service transmission: Simultaneous transmission of data, voice and video signals.

Telecommunications Network:

Metropolitan Area Network (MAN): for city-wide fibre-optic network expansion.

Fibre to the Home (FTTH): supports high-bandwidth broadband access services.

Cloud Computing:

Cloud data centre interconnection: enables high-speed data transmission between multiple data centres.

Video Surveillance:

HD Video Transmission: Supports real-time transmission of multiple HD video signals.
