Choosing the right fiber optic cabling for your commercial network in Los Angeles can shape your business’s connectivity, speed, and future growth. With two main types of fiber optic cables—multimode and singlemode—understanding their differences is key to making an informed decision. This guide breaks down the core distinctions, typical applications, speeds, costs, and pros and cons of each fiber type. It also includes a decision flowchart to help you select the best option for your network needs. Gbit Tech’s expertise in both multimode and singlemode fiber ensures scalable UniFi deployments tailored for Los Angeles businesses.

Core Differences Between Multimode and Singlemode Fiber
Understanding the physical and technical differences between multimode and singlemode fiber is the first step.
Core Size
Multimode fiber has a larger core diameter, typically 50 or 62.5 microns. This wider core allows multiple light modes to travel simultaneously. Singlemode fiber has a much smaller core, about 8 to 10 microns, allowing only one light mode to pass through.
Distance and Signal Loss
Multimode fiber is designed for shorter distances, usually up to 550 meters for 10 Gbps speeds. Signal dispersion limits its reach. Singlemode fiber supports much longer distances, from several kilometers to tens of kilometers, with minimal signal loss.
Light Sources
Multimode fiber uses LED or vertical-cavity surface-emitting lasers (VCSELs), which are less expensive but have limited range. Singlemode fiber requires laser diodes, which are more costly but provide higher precision and longer reach.
Cost
Multimode fiber cables and transceivers generally cost less upfront. Singlemode fiber components are pricier but offer better long-term value for large-scale or long-distance networks.
Applications in Los Angeles Commercial Networks
Different fiber types suit different network needs in commercial settings across Los Angeles.
Multimode Fiber
Ideal for short runs within buildings or campuses. It works well for data centers, office floors, and intra-building connections where distances are under 500 meters. Multimode fiber supports high-speed connections for local area networks (LANs) and is common in environments where cost control is important.
Singlemode Fiber
Best for long-haul connections, backbone infrastructure, and inter-building links across a campus or city. Singlemode fiber supports wide area networks (WANs) and metropolitan area networks (MANs), making it suitable for connecting multiple commercial sites in Los Angeles or linking to data centers.
Speed and Performance Comparison
Both fiber types support high speeds, but their performance varies with distance.
Fiber Type | Typical Max Distance | Max Speed |
Multimode | 10 Gbps | Up to 550 meters |
Singlemode | 100 Gbps+ | 10+ kilometers |
Multimode fiber is sufficient for most office and campus environments where runs are short. Singlemode fiber is preferred for future-proofing networks that may require ultra-high speeds over long distances.
Pros and Cons of Multimode and Singlemode Fiber
Multimode Fiber
Pros
Lower initial cost for cables and transceivers
Easier to install and terminate due to larger core size
Suitable for most commercial building networks
Cons
Limited distance range
Higher modal dispersion can reduce signal quality over longer runs
Less future-proof for very high-speed or long-distance needs
Singlemode Fiber
Pros
Supports very long distances with low signal loss
Higher bandwidth and speed potential
More future-proof for expanding networks
Cons
Higher cost for components and installation
Requires more precise handling and termination
Transceivers are more expensive
