Multimode Fiber Optic Cable

Multimode Fiber (MMF) cables feature a larger core diameter ranging from 50 to 100 μm, allowing multiple light paths or "modes" to propagate simultaneously. This design simplifies alignment and installation, making MMF ideal for short to medium-distance data transmission where cost-effectiveness and ease of deployment are paramount.

Key Features

Core Size & Light Transmission

• Core Diameter: Larger 50-100 μm core supports multiple light modes, enhancing flexibility and simplifying installation processes.
• Light Transmission: While supporting multiple paths increases light signal capacity, it can lead to modal dispersion, which may limit transmission range and bandwidth.

Bandwidth

• Sufficient Capacity: Although offering lower bandwidth compared to SMF, MMF provides adequate performance for short-distance applications like Local Area Networks (LANs).

Transmission Distance

• Short to Medium Range: Optimally effective for distances between 300 to 550 meters, depending on fiber grade (e.g., OM3 or OM4), making it suitable for data centers and campus networks.

Attenuation

• Higher Signal Loss: Due to the larger core and multiple light paths, MMF experiences greater attenuation, which becomes more noticeable as transmission distance increases.

Typical Applications

Local Area Networks (LANs)

• Widely utilized in enterprise and campus networks to connect office spaces, meeting rooms, and IT infrastructure, supporting high-bandwidth internal communications within 300-550 meters.

Data Centers

• Commonly used for short-reach connections between racks and equipment within data centers, facilitating high-speed links essential for storage, backup, and processing tasks.

Campus Networks

• Suitable for interbuilding connections within universities, hospitals, and corporate facilities, offering a cost-effective solution for short-distance data transmission needs.

Audiovisual Systems

• Frequently deployed in AV setups to transmit video and audio data over short distances, ensuring high-quality signal delivery in broadcasting studios, theaters, and large event venues.
