Panduit F62ELLNSNSNM012 OM1 LC to SC Duplex Fiber Patch Cord

The Panduit F62ELLNSNSNM012 is a 2-fiber OM1 multimode patch cord terminated with LC connectors on one end and SC duplex connectors on the other — purpose-built for environments where legacy multimode infrastructure is still active and needs reliable, compact interconnects. If your fiber closet has a mix of LC-port transceivers and SC-port patch panels (or vice versa), this cable solves the connector mismatch without adapters or workarounds. Browse the full Panduit fiber and cabling line for trunk assemblies, cassettes, and enclosures that pair with this cord.

Overview

OM1 multimode fiber has a 62.5-micron core and supports 10 Gigabit Ethernet only at very short distances — its primary value today is extending the usable life of installed plant that was built before OM3 and OM4 became the standard. In a data center retrofit, a campus IDF refresh, or a building where fiber was pulled 15 to 20 years ago, replacing every link is rarely practical or justified. The F62ELLNSNSNM012 gives network and cabling teams a clean way to keep those links serviceable without overbuilding. Explore the full range of fiber optic cables and assemblies to find OM3, OM4, and OS2 alternatives when the application calls for higher-grade glass.

The 1.6 mm cable diameter is intentionally slim. Standard duplex fiber patch cords often run 2.0 mm or 3.0 mm per strand — the narrower 1.6 mm build reduces bundle bulk in high-density trays and ladder racks, making cable management less of a fight in tight spaces. For teams managing fully populated 48-port patch panels or stacked cabinets, that difference is practical, not cosmetic.

The LSZH (Low Smoke Zero Halogen) jacket is the right call for indoor plenum-adjacent or enclosed spaces where local codes or building standards call for reduced-smoke materials. Unlike PVC jackets, LSZH compounds don't release corrosive halogen gases under heat — relevant in switch rooms, data closets, and any space where occupant safety or sensitive electronics are a concern. If you are running this cable in a North American riser or plenum environment, confirm your local code requirements, as LSZH and OFNR/OFNP ratings address different standards.

Key Features

• OM1 Multimode Fiber (62.5/125 µm): Maintains compatibility with installed OM1 infrastructure — avoids costly wholesale fiber replacement in buildings where legacy optics and transceivers are still in service.
• LC to SC Duplex Termination: Bridges the most common mixed-connector scenario in maturing fiber plants. LC ports dominate modern SFP transceivers; SC ports are common on older patch panels and switches. This cord eliminates the need for LC-to-SC hybrid adapters that introduce additional mating points and potential insertion loss.
• 1.6 mm Cable Diameter: Measurably slimmer than standard 2.0 mm or 3.0 mm duplex builds. Reduces pathway congestion in crowded cabinets and trays — a real factor when routing dozens of cords through the same horizontal management ring.
• LSZH Jacket: Low Smoke Zero Halogen construction is specified for indoor environments where codes or facility standards require reduced smoke emission and no halogenic combustion byproducts. Common requirement in European installations and increasingly adopted in North American commercial construction.
• 2-Fiber Duplex Construction: Two fibers in a single jacket handle both the transmit and receive paths of a full-duplex link — one cord, one run, no loose simplex strands to manage separately.
• Legacy Multimode Deployment Fit: Designed specifically for installed-base environments, not for new high-density builds chasing 40G or 100G. If your optics are SX or LX/LH modules designed for OM1, this cord is specced correctly for those transceivers.

Integration and Compatibility

The F62ELLNSNSNM012 is compatible with any equipment using standard LC (IEC 61754-20) and SC (IEC 61754-4) fiber connectors on OM1 multimode links. Common pairings include legacy Cisco, HP ProCurve, and Brocade switches and routers with SC-port line cards, connected to modern SFP transceivers or media converters with LC interfaces. It also integrates cleanly with Panduit fiber cassettes and enclosures that use LC adapter plates, bridging out to SC-terminated trunk segments or equipment ports.

For teams running IP video infrastructure — NVRs, encoders, or core switches with fiber uplinks — connecting legacy fiber runs to current-generation equipment often requires exactly this LC-to-SC bridge. Pair with a PoE network switch featuring SFP fiber uplink ports when extending camera network segments over existing OM1 plant. Note that OM1 distance limits at 1 Gbps (275 m) and 10 Gbps (33 m) apply — confirm transceiver specs before committing to a link length.

Frequently Asked Questions

Q: What fiber type is the F62ELLNSNSNM012 and what are its bandwidth limitations?

A: The F62ELLNSNSNM012 uses OM1 multimode fiber with a 62.5/125 µm core. OM1 supports 1 Gigabit Ethernet up to approximately 275 meters and 10 Gigabit Ethernet up to approximately 33 meters. It is not suitable for 40G or 100G applications.

Q: What connectors are on each end of this patch cord?

A: One end terminates in LC duplex connectors; the other end terminates in SC duplex connectors. This makes it a direct solution for bridging LC-port SFP transceivers to SC-port patch panels or switch line cards.

Q: Why choose a 1.6 mm cable diameter over a standard 2.0 mm or 3.0 mm build?

A: The 1.6 mm construction reduces bulk in high-density patching environments. When routing large quantities of cords through horizontal managers, trays, or cabinets, the slimmer diameter eases routing and reduces strain on bend-radius requirements.

Q: Is the LSZH jacket suitable for North American plenum or riser applications?

A: LSZH (Low Smoke Zero Halogen) is a jacket material standard focused on smoke and gas emission characteristics, primarily specified under European standards (EN 50575). It is not the same as North American OFNP (plenum-rated) or OFNR (riser-rated). Verify local code requirements before installing in rated plenum or riser spaces.

Q: Can this cable be used in new high-density fiber builds targeting 10G or beyond?

A: It is not the best fit for new high-density 10G builds. OM1 supports 10GbE only to 33 meters, and its bandwidth capacity is significantly lower than OM3 or OM4. For new installations targeting 10G or higher, OM3 or OM4 multimode fiber is the appropriate choice.

Q: Is this a duplex or simplex cord?

A: This is a duplex cord — two fibers under a single 1.6 mm jacket, handling both transmit and receive paths in one assembly. No separate simplex strands to manage.

The F62ELLNSNSNM012 is one of those cables that gets specified when a site audit reveals the installed plant is OM1 and the budget doesn't support a full fiber pull. The 1.6 mm duplex LSZH construction is compact enough to keep congested patch fields manageable, and the LC-to-SC termination solves the connector mismatch that comes up constantly when mixing generation-one fiber infrastructure with current-generation SFP transceivers.

Technical Highlights:

• LC-to-SC Duplex Termination: Eliminates the adapter middleman — each adapter plate in a fiber path adds an insertion loss mating point; a native LC-to-SC cord removes that variable entirely.
• 1.6 mm Cable Diameter: Noticeably easier to route in fully populated cabinets compared to 2.0 mm or 3.0 mm builds — especially when you're threading 20 or 30 cords through the same 1U horizontal manager.
• LSZH Jacket: Specified for enclosed indoor spaces where low-smoke materials are required — a common stipulation in European commercial builds and increasingly in North American facilities with stringent life-safety standards.

Deployment Considerations:

• Confirm your transceiver's OM1 support before ordering — SX optics are typically OM1/OM2 compatible, but many current-generation SFP+ modules are optimized for OM3 or OM4 and may not meet spec on OM1 at the distances you need.
• LSZH and OFNP/OFNR are separate ratings addressing different standards — if your local code requires plenum or riser certification, LSZH alone does not satisfy that requirement; verify with your AHJ before installation.

This cord earns its place in IDF-to-equipment runs within a campus or building where OM1 was the installed standard and replacing the fiber plant isn't on the table — hospital wings, university buildings, and government facilities with long fiber lifecycles are the clearest fits.
