Fiber and communications infrastructure knowledge brief Published 17 Nov 2023

Prepared for preliminary research by the ROGER FIBRE knowledge desk. Confirm optical interfaces, port or core capacity, electrical input and output, enclosure protection, thermal design and installation limits against current standards and product documentation.

Yes, 4-core multimode optical cables are available, including OM4 types suitable for high-speed data transmission in indoor and data center environments.

Overview

Multimode optical fiber cables are designed with a larger core diameter (typically 50 µm or 62. 5 µm) that allows multiple light modes to propagate simultaneously, making them ideal for short- to medium-distance data transmission in enterprise networks, data centers, and campus environments. A 4-core multimode cable contains four individual fiber strands within a single jacket, enabling multiple parallel connections or redundancy in network setups.

OM4 4-Core CablesOM4 multimode fiber is laser-optimized with a 50/125 µm core/cladding diameter and supports high-speed data rates: 10 Gbps up to 400–550 meters40/100 Gbps up to 150 metersBackwards compatible with OM3 fiberTypically used with VCSEL lasers for efficient transmission 4-core OM4 cables are commonly available in tight-buffered indoor designs (GJFJV type) with LSZH (Low Smoke Zero Halogen) jackets for safe indoor deployment. They are lightweight, flexible, and easy to install, making them suitable for interconnects between equipment racks or telecom enclosures.

Applications

Data centers: High-speed server-to-switch connectionsEnterprise LANs: Backbone or horizontal cablingShort-reach high-bandwidth links: Up to 400 meters at 10 GbpsIndoor distribution: Tight-buffered cables for easy routing and termination AvailabilityManufacturers offer 4-core multimode cables in various configurations, from 4-core to 96-core, with options for custom lengths and indoor/outdoor ratings. These cables are widely used in modern network deployments where multiple parallel fiber connections are needed without increasing cable bulk. In summary, 4-core multimode optical cables, including OM4 types, are readily available and are suitable for high-speed, short- to medium-distance applications in data centers and enterprise networks.

They provide flexibility, high bandwidth, and ease of installation for multi-fiber connections.

OverviewApplicationsComparison with single-mode fiberTypesEncircled fluxExternal links

Multi-mode optical fiber is a type of optical fiber mostly used for communication over short distances, such as within a building or on a campus. Multi-mode links can be used for data rates up to 800 Gbit/s. Multi-mode fiber has a fairly large core diameter that enables multiple light modes to be propagated and limits the maximum length of a transmission link because of modal dispersion. The standard G.651.1 defines the mos
