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. To explore the full range of LC fiber optic connectors with 1.25mm ferrule for SFP and SFP+ interfaces, see our dedicated product page.
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 unsure which fiber type suits your deployment, our guide on single mode vs multimode fiber differences and selection criteria covers the key technical and cost 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
The compact uniboot design consolidates two fibers into a single boot, cutting cable volume nearly in half compared to standard duplex assemblies. This makes the LC UPC uniboot high-density patch cable an efficient choice for structured cabling between patch panels, ODF frames, and top-of-rack switches where port density is critical. You can find ready-to-deploy options in our LC to LC uniboot singlemode duplex patch cord for high-density data center cabling.
Telecom central offices frequently require hundreds of fiber links within limited rack space. The 1.25mm SFF ferrule and slim uniboot housing allow more connections per rack unit, reducing airflow obstruction and simplifying cable management for high-density uniboot LC fiber jumper installations in carrier-grade environments.
For campus and building backbone runs that link distribution switches to core routers, this space-saving LC uniboot patch cord delivers reliable duplex connectivity. The injection-molded locking tabs resist accidental disconnection during routine maintenance in enterprise fiber backbone deployments.
In fiber-to-the-home and premise distribution systems, the uniboot form factor simplifies cable routing through tight conduits and distribution boxes. Its push-pull LC locking mechanism enables fast field installation and removal, supporting efficient uniboot fiber cable deployment in FTTH access networks.
Optical CATV headend equipment demands stable, low-loss connections between transmitters, receivers, and splitter modules. The 100% optically tested LC uniboot fiber assembly ensures consistent signal integrity across CATV headend fiber patching links.
FAQ
Q1: What does "uniboot" mean in an LC fiber patch cable?
A: Uniboot refers to a design that houses two optical fibers inside a single cable body and terminates them under one shared boot at each connector end. Compared to a standard dual-cable duplex assembly, an LC uniboot high-density fiber optic patch cable reduces cable diameter and weight, making it easier to manage in crowded racks and patch panels.
Q2: How does an LC uniboot cable differ from a standard LC duplex patch cord?
A: A standard LC duplex patch cord uses two separate 2.0mm or 3.0mm cables joined by a clip. A compact LC uniboot duplex fiber cable merges both fibers into one round jacket, roughly halving the cable volume. This improves bend routing in tight spaces and reduces clutter behind patch panels.
Q3: Can I switch the polarity (Tx/Rx) on this uniboot patch cable?
A: Many LC uniboot designs allow polarity reversal by flipping the fiber positions within the connector housing - no need to re-terminate or swap cables. Please confirm with our sales team whether the specific uniboot LC patch cord variant you order supports tool-free polarity switching.
Q4: What is the ferrule size used in this LC uniboot connector?
A: The LC connector uses a 1.25mm diameter precision zirconia ceramic ferrule, which is half the size of SC or FC ferrules. This small form factor ferrule is the reason LC connectors achieve higher port density per panel unit, making them the standard interface for SFP and SFP+ transceiver modules per IEC 61754-20.
Q5: Is this cable available in both riser-rated and plenum-rated jacket options?
A: Yes. We offer both riser (OFNR) and plenum (OFNP) jacket versions. Plenum-rated LC uniboot cables use low-smoke materials suitable for installation in air-handling spaces above drop ceilings or under raised floors, meeting fire safety code requirements for those environments.
Q6: What insertion loss and return loss should I expect?
A: Each cable is 100% optically inspected before shipment. Typical values depend on fiber mode and polish type - for example, UPC singlemode achieves ≤0.2dB insertion loss and ≥50dB return loss. To understand how PC, UPC, and APC end-face polishing affect these performance figures, see our in-depth article on PC vs UPC vs APC fiber connector polish types and their impact on return loss. Refer to the specification table on this page for the complete performance matrix across all connector and fiber types.
Q7: Can this LC uniboot patch cable be ordered in custom lengths?
A: Yes. Standard lengths range from 0.5m to 30m, and we accept custom cable length orders for project-specific requirements. Contact us with the exact length, quantity, and jacket type needed for your installation to receive a quotation with lead time.
Q8: What should I verify before placing a bulk order for LC uniboot cables?
A: Before ordering, please confirm: (1) fiber mode - singlemode or multimode; (2) polish type - PC, UPC, or APC; (3) required cable lengths; (4) jacket rating - riser or plenum; (5) quantity per length; (6) any labeling or color-coding requirements. Providing these details upfront ensures accurate production and avoids delays on bulk LC uniboot fiber patch cable orders.
