What is LC patch cable?
LC-LC fiber optic patch cord is a small compact patch cable very popularly used in many applications. These network solutions include telecommunication networks, LANs, data processing networks, device terminations and premises distributions. LC-LC patch cords are designed to deliver fast Ethernet solutions in Gigabit applications and ATM applications with less space consumption.

Features
Meets Growing Demands for SFF Solutions
LC connectors are manufactured with only a 1.25mm diameter ferrule which is a great advantage for densely populated fiber optic network. The LC connector is manufactured under the standard IEC 61754-20 for high density connections such as in SFP, XFP and SFP+ transceivers.
Singlemode or Multimode LC-LC, Riser or Plenum Rated
We supplies LC-LC fiber optic cable assemblies, with single mode (9/125 OS1, OS2), duplex and multimode (50/125 and 62.5/125) options. If you are comparing OM3 and OM4 for your specific link distance requirements, our detailed breakdown of OM3 vs OM4 multimode fiber performance differences and selection guidance covers the key bandwidth and reach considerations. You can choose if it's for riser application or plenum connections or if you want it to be completely customized, you can contact us to know more about our OEM/ODM service for LC-LC patch cords.
Easy and Convenient Pull Out
Built with a conveniently snap in configuration, LC-LC connections are equipped with locking mechanisms that are similar to the retaining tab of an RJ45 connector. Now it's easy to connect and disconnect the connector from the device. The locking tabs are injection-molded with enhanced durability in resisting pulls, strains, snags, and impacts during cabling installs and maintenance.
Safe and Tested Fiber Assembly with Low Insertion Loss
Our patch cords are 100% optically inspected and tested to bring low insertion loss not exceeding 0.02 dB.
Applications
10G Data Center Switch-to-Server Connections
OM3 laser-optimized 50/125μm fiber supports 10 Gigabit Ethernet up to 300 meters at 850nm. The uniboot form factor reduces cable bulk between top-of-rack switches and server SFP+ ports, making the LC UPC OM3 uniboot high-density multimode patch cable a practical option for 10G data center cabling where rack space is constrained. You can browse ready-to-order options on our LC uniboot OM3 multimode duplex fiber patch cord product page.
High-Density SFP+ Transceiver Patching in Network Closets
Network closets and intermediate distribution frames often host dozens of SFP+ multimode transceivers in a compact footprint. The 1.25mm SFF LC connector combined with the slim uniboot jacket allows tighter cable routing and cleaner bundling, improving airflow compared to standard duplex OM3 LC fiber jumper assemblies.
Storage Area Network (SAN) Fibre Channel Links
Fibre Channel over multimode fiber commonly uses LC interfaces at 8G and 16G speeds. The compact LC uniboot OM3 cable for SAN environments simplifies patching between HBA ports and FC switches, and the injection-molded locking tab prevents accidental disconnections that could interrupt storage traffic.
Enterprise Multimode LAN Backbone Runs
For building backbone links connecting access-layer switches to distribution-layer equipment over multimode fiber, this space-saving uniboot OM3 multimode patch cord provides a reliable duplex connection. Its reduced cable diameter eases installation through cable trays, conduits, and raised-floor pathways common in enterprise campus fiber networks. For a broader look at how LC uniboot cables fit into high-density structured cabling strategies, see our guide on high-density LC fiber connector solutions using uniboot design in campus and data center environments.
Structured Cabling for Lab and Testing Environments
Test benches, R&D labs, and manufacturing floors frequently reconfigure fiber connections. The push-pull LC locking mechanism and compact uniboot cable body enable fast connect-disconnect cycles, making the OM3 uniboot fiber patch cable for testing setups an efficient choice where frequent re-patching is required.
FAQ
Q1: What is the maximum transmission distance for this OM3 uniboot patch cable at 10G?
A: OM3 laser-optimized 50/125μm multimode fiber supports 10 Gigabit Ethernet (10GBASE-SR) up to 300 meters at 850nm wavelength. For shorter intra-rack or cross-cabinet connections typical in data centers, the LC UPC OM3 uniboot multimode fiber cable delivers consistent performance well within this reach.
Q2: What is the difference between OM3 and OM4 in an LC uniboot patch cable?
A: Both OM3 and OM4 use 50/125μm laser-optimized multimode fiber, but OM4 has higher modal bandwidth (4700 MHz·km vs. 2000 MHz·km at 850nm), which extends the 10G reach to 400 meters and supports 40G/100G parallel optics over longer distances. If your links are under 300 meters and running at 10G, an OM3 uniboot high-density multimode patch cord is a cost-effective choice. For a side-by-side technical comparison, our article on multimode fiber types OM1 through OM5 - specifications and application differences explains when each grade is the right fit.
Q3: Can this OM3 uniboot cable work with VCSEL-based SFP+ transceivers?
A: Yes. OM3 multimode fiber is specifically optimized for 850nm VCSEL (Vertical-Cavity Surface-Emitting Laser) light sources used in standard 10G SFP+ SR transceivers. The LC UPC connector interface directly mates with SFP+ transceiver ports without any adapter.
Q4: Does the uniboot design affect optical performance compared to standard duplex cables?
A: No. The uniboot housing consolidates two fibers into one cable body, but each fiber maintains the same 50/125μm core structure and polished ferrule quality. Insertion loss and return loss remain consistent with standard duplex LC multimode patch cord performance specifications listed in the table above.
Q5: Is this cable available in plenum-rated jacket for ceiling space installation?
A: Yes. We supply both riser (OFNR) and plenum (OFNP) rated versions. For installations routed through air-handling plenums above drop ceilings, the plenum-rated LC uniboot OM3 multimode cable meets fire safety codes with low-smoke, flame-retardant jacket materials. For guidance on choosing the right jacket type and routing approach for indoor deployments, our walks through the key considerations.
Q6: What does the aqua color indicate on this OM3 patch cable?
A: Aqua is the TIA-598 standard color designation for laser-optimized OM3 and OM4 multimode fiber. This color coding helps technicians instantly distinguish multimode cables from yellow singlemode cables in mixed-fiber environments, preventing cross-connection errors during OM3 uniboot fiber cable installation.
Q7: Can I order custom lengths and quantities for a project deployment?
A: Yes. We offer standard lengths from 0.5m to 30m and accept custom length orders. For project-scale LC uniboot OM3 patch cable bulk orders, please provide the required lengths, quantities per length, jacket rating, and any labeling specifications so we can prepare an accurate quotation and production schedule.
Q8: How should I clean the LC UPC connector end-face before installation?
A: Use a dedicated LC one-click fiber cleaner or a lint-free wipe with IPA (isopropyl alcohol) to clean each 1.25mm ferrule end-face before mating. Dust or contamination on even one ferrule can increase insertion loss significantly. We include protective dust caps on every connector - keep them on until the moment of installation. For a full step-by-step cleaning and maintenance routine, our fiber optic patch cord maintenance and end-face cleaning guidelines provides best-practice procedures for field technicians.
