Engineering Applications OM2 Multimode Fiber Patch Cord
Enterprise park local area network backbone link
Between campuses or internal buildings in corporate campuses, OM2 patch cords are commonly used to build gigabit Ethernet backbone links. Its 50/125μm fiber core paired with an 850nm light source can stably support 1Gbps transmission up to 550 meters, covering most campus access layer to aggregation layer connection needs. Compared to OM3/OM4, OM2 is less expensive and is ideal for traditional network retrofit projects with limited budgets that do not need to upgrade to 10G or above.
Interconnection of internal data center equipment (short-distance cabinets).
In standard cabinets or between adjacent cabinets, OM2 patch cords are used to connect servers, storage devices, and rack-top switches. For 10G speeds, OM2 supports link distances up to 82 meters, fully meeting cabling requirements within a single module or between adjacent modules. Its excellent bending performance and universal LC/SC interface facilitate flexible jumping on high-density patch panels, ensuring low insertion loss and high feedback loss transmission during daily data center operations.
Industrial automation and video surveillance systems
In environments with strong electromagnetic interference, such as factory workshops or large warehouses, OM2 patch cords serve as fiber optic links between PLC control cabinets and remote I/O modules or industrial switches. At the same time, paired with IP HD cameras, it enables long-distance, attenuation-free video backflow (up to 550 meters @ 100Mbps). Its Riser (OFNR) sheath is available to meet different fire resistance requirements, effectively isolating electromagnetic noise generated by motors and frequency converters, ensuring real-time reliability of control commands and video signals.
Fiber to Desktop (FTTD) office network
In government, financial, or design office environments with high bandwidth and confidentiality requirements, OM2 patch cords can be deployed directly to user workstations. Paired with desktop optical transceivers, it provides 1Gbps dedicated bandwidth to the desktop, eliminating the risk of electromagnetic leakage and lightning strikes associated with copper cables. OM2's lightweight structure and standard SC/LC interface facilitate flexible connection between wall information panels and desktop terminals, enabling a stable, high-speed all-optical office network.

OM2 Multimode Fiber Patch Cord Selection Guide
When choosing between an OM2 and OM3 multimode fiber patch cord, consider your network requirements. If your application mainly involves general - purpose short - distance connections in LANs, ODFs, or enterprise networks, and the speed requirements are mostly 1G or 10G, OM2 is a suitable choice. Its lower cost and reliable performance for these speeds make it a cost - effective solution.
However, if your network demands higher - speed connections such as 40G, or if you need longer reach at 10G, OM3 would be more appropriate. OM3's optimization for 850nm VCSEL and better optical performance at higher speeds make it a better fit for more demanding data center and enterprise network applications.
Parameter - Best Fit
| Parameter | Best Fit |
|---|---|
| General - purpose 1G/10G short - distance connections in LANs, ODFs, and enterprise networks | OM2 |
| 40G applications or longer reach at 10G | OM3 |
| Cost - sensitive short - distance applications | OM2 |
| High - speed data center and enterprise network applications | OM3 |
Mixed deployment guidance:
In a network with a mix of general - purpose and high - speed requirements, OM2 can be used for less demanding connections like user - device connections at 1G or 10G. OM3 can be deployed for high - speed sections such as server - to - switch connections in data centers or high - bandwidth enterprise applications. This approach allows for cost - effective deployment while still meeting the performance needs of different parts of the network.
