What is LC 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. For a deeper look at how this translates into real-world deployments, see our guide on high-density LC fiber connector solutions for SFP+ and data center environments.
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. 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 LC multimode duplex OM4 patch cord is engineered specifically for environments where connector density, short-reach bandwidth, and fast hot-swap patching matter more than distance. Because the 1.25mm SFF ferrule is half the diameter of a standard SC ferrule, this LC OM4 duplex fiber jumper fits twice as many ports into the same 1U of panel space - which is why the following scenarios are its primary deployment targets.
High-Density SFP+ / QSFP+ Transceiver Racks
Slots straight into 10G SFP+, 25G SFP28, and 4×10G QSFP+ break-out cages. The 1.25mm SFF LC patch cable keeps port-to-port pitch at 6.25mm, matching the mechanical spacing defined by IEC 61754-20 for stackable transceiver cages.
10G / 40G / 100G Short-Reach Multimode Links
OM4 50/125 laser-optimized fiber delivers 10GBASE-SR up to 400 m, 40GBASE-SR4 up to 150 m, and 100GBASE-SR10 up to 150 m. This makes the OM4 LC-LC duplex fiber optic cable the default short-reach jumper for spine-leaf fabric inside a single data hall. If you are evaluating whether to deploy OM3 or OM4 for your project, our OM3 vs OM4 multimode fiber comparison guide covers the key distance, bandwidth, and cost trade-offs in detail.
Hot-Swap Patching in Live 24×7 Panels
The RJ45-style snap-in latch releases with one finger - no tools, no adjacent-port disturbance. Field technicians prefer this LC duplex OM4 patch lead for production panels where accidental tugs on neighbouring cables cause service hits.
Storage Area Networks (Fibre Channel 16G / 32G)
SAN directors from Brocade and Cisco use duplex LC on every port. The multimode OM4 LC to LC jumper supports 16GFC up to 125 m and 32GFC up to 100 m - covering the longest row-to-row reach inside most enterprise SAN fabrics.
Riser & Plenum Structured Cabling (OFNR / OFNP)
For bulk order buyers building out riser shafts or air-plenum ceilings, the LC OM4 duplex plenum patch cord is available with OFNR or OFNP rated jackets that meet NFPA 262 and UL 910 fire-safety requirements - often specified on US federal and healthcare projects.
OEM / ODM Wholesale for System Integrators
We accept bulk OEM orders with custom printed labels, colour-coded boots, and non-standard breakout lengths (down to 0.5 m). Wholesale LC multimode duplex jumper buyers can combine mixed 0.9 / 2.0 / 3.0 mm cable diameters on the same PO.
Wide-Temperature Industrial Fibre Runs
The −40 ~ 75 °C operating window exceeds standard commercial spec by 20 °C on the low end, letting the 50/125 OM4 LC-LC duplex patch cable survive unconditioned switch rooms, outdoor shelters, and trackside telecom cabinets without thermal cycling failure.
FAQ
Q1: What makes the 1.25mm SFF ferrule better than the 2.5mm ferrule on an SC cable?
A: The smaller ferrule halves the pitch between ports, which is exactly why IEC 61754-20 chose 1.25mm for LC. A 1U panel that fits 24 SC duplex ports can fit 48 LC duplex ports using this LC multimode duplex OM4 patch cord - doubling port density without enlarging the rack footprint.
Q2: Will this LC to LC OM4 fiber jumper run 40G and 100G?
A: Yes. OM4 laser-optimized 50/125 fiber supports 40GBASE-SR4 and 100GBASE-SR10 on short-reach multimode links. For 40G/100G parallel optics you would use two LC OM4 duplex jumpers or move to an MPO trunk - but for aggregation between two duplex-LC SFP+/QSFP+ break-out ports, this cord is the correct choice.
Q3: What exactly does IEC 61754-20 compliance guarantee?
A: IEC 61754-20 is the international dimensional and mating standard for LC interface connectors. The IEC 61754-20 LC duplex jumper produced here mates reliably with any compliant transceiver or adapter from Cisco, Juniper, Arista, HPE, Finisar, and other manufacturers - no vendor lock-in.
Q4: Can I order this OM4 LC patch cord in OFNP plenum rating for a wholesale project?
A: Yes. Bulk buyers can specify OFNR (riser) or OFNP (plenum) jackets on the same PO. MOQ for customised jacket ratings is typically 100 pieces per length-SKU; mixed lengths from 0.5 m to 30 m ship together.
Q5: What is the lead time for a bulk order of LC OM4 duplex fiber cables?
A: Standard configurations (aqua LSZH, 2.0 mm, 0.5–10 m) ship in 3–5 working days from stock. Custom OEM orders with printed labels, colour-coded boots, or non-standard lengths typically require 7–12 working days. Large 5,000+ piece tenders are quoted individually.
Q6: Is the ≤0.2 dB low insertion loss guaranteed on every unit?
A: Every LC duplex OM4 patch lead is 100% interferometer-inspected and insertion-loss tested against a reference-grade master. Typical IL measured in-line is ≤0.2 dB at 850 nm and ≤0.15 dB at 1300 nm. Individual test reports are available on request for bulk order quality submittals.
Q7: Which cable diameter should I choose - 0.9, 2.0, or 3.0 mm?
A: Use 3.0 mm for patch panel to equipment runs where crush resistance matters, 2.0 mm for dense 1U patch fields, and 0.9 mm tight-buffered for fanout assemblies and inside cassettes. All three diameters are offered on the same 50/125 OM4 LC-LC duplex patch cable family.
Q8: Is this OM4 jumper backward compatible with OM3 transceivers?
A: Yes. OM4 fiber runs at higher bandwidth than OM3 but shares the same 50/125 core geometry, so the LC multimode duplex patch cord works on OM3 equipment with no modal mismatch. Link reach will be governed by the lower-grade leg in a mixed OM3/OM4 channel.
Q9: What operating temperature can I expect in an outdoor street cabinet?
A: The operational range is −40 °C to +75 °C, with storage −45 °C to +85 °C. This makes the high-density LC OM4 patch cable for SFP+ deployments usable in unconditioned cabinets across most European, North American, and Middle-Eastern climate zones.
Q10: How does the RJ45-style latch compare to push-pull uniboot cables?
A: The snap-in latch is simpler, cheaper, and widely familiar to field technicians. Uniboot cables save roughly 25% on jumper cross-section but cost more per unit. For standard 1U patch fields, the RJ45-style LC duplex jumper is the mainstream choice; uniboot is a separate product line.
Q11: Do you ship this LC-LC OM4 duplex cord under your own brand or OEM?
A: Both. Direct buyers receive Evolux-branded labels and packaging. OEM / wholesale LC OM4 duplex supplier orders ship with the buyer's own printing, box design, and factory certificate of origin documentation.
Q12: What should I confirm before placing the order?
A: Please confirm polish type (UPC or APC) - see our PC vs UPC vs APC connector polish guide if you are unsure which finish suits your link, jacket material (LSZH / OFNR / OFNP / PVC), cable diameter (0.9 / 2.0 / 3.0 mm), length, colour-coded boot requirement, and whether printed length markers or serial-numbered labels are required on each assembly.
