Multi-Mode Cables
Frequently Asked Questions
Multimode fiber cables are usually cheaper than their single-mode cousins. They are also easier to install as they are more resistant to breakage. They perform well over short distances.
Long distances of propagation limit the performance of multimode fibers. Compared with single-model fiber cables optical pulses suffer significant distortion and losses in multimode fiber cables.
The core diameter of a multi-mode fiber cable is typically a few tens of micrometers wide.
Unlike a bare fiber, a multimode fiber cable has a special tubing that consists of multiple layers of protective materials that isolate heat, noise, and in some cases interference with electromagnetic waves. Additionally, fiber cables often come with end-connectors that make it easy to couple these cables with other devices.
The grade refers to the performance level of a multimode fiber cable. There are 5 distinct grades: OM1, OM2, OM3, OM4, and OM5 based on ISO/IEC 11801 standard. Each of these grades corresponds to a particular bandwidth and transport distance, with OM1 designating a standard 62.5um multimode glass, OM3 - 50 um enhanced glass core capable of 300m transmission at 10GB bandwidth and M5 reserved for multimode cables that can transmit up to 550m at 10Gb bandwidth.
The maximum distance depends on the wavelength of light transmitted. It can reach up to 10 miles for certain wavelengths. For these maximum distances, the bandwidth of the signal will drop significantly.
Multi-Mode Fiber Optic Cables: High-Speed Data Transmission for Short to Medium Distances
Multi-mode fiber optic cables are a key solution for high-speed data transmission over short to medium distances. They are widely used in applications such as local area networks (LANs), data centers, audio/video transmission systems, and industrial automation. At FindLight, we offer a comprehensive selection of multi-mode fiber cables from trusted global suppliers, designed to meet diverse performance requirements.
What Are Multi-Mode Fiber Cables?
Multi-mode fiber cables use an optical fiber with a larger core diameter—typically 50 or 62.5 microns—allowing multiple light modes to propagate simultaneously. This characteristic enables higher data throughput compared to traditional copper cables while keeping costs lower than single-mode fiber for short-range communication.
Because the light bounces at multiple angles within the fiber core, multi-mode fibers are ideally suited for distances up to 2 kilometers, depending on the transmission speed and cable grade. OM1, OM2, OM3, OM4, and OM5 are the most common types, with OM5 being optimized for higher bandwidth and wavelength multiplexing in advanced networks.
Advantages of Multi-Mode Fiber Cables
-
Cost-Effective: Multi-mode cables and the associated transceivers are generally less expensive than single-mode options, making them a budget-friendly choice for in-building and campus-wide deployments.
-
Simplified Connectivity: With a larger core size, multi-mode fiber allows easier alignment with connectors and lower precision requirements for transceivers, resulting in simplified installation and maintenance.
-
High Bandwidth Over Short Distances: These cables are designed for high-speed data transmission up to 100 Gbps within shorter ranges, making them ideal for data centers, enterprise networks, and telecommunication hubs.
-
Compatibility: Multi-mode cables are compatible with a wide range of fiber connectors such as LC, SC, ST, and MTP/MPO, supporting various deployment configurations.
Applications
Multi-mode fiber cables are widely used in:
-
LAN and SAN infrastructures
