Hubbell FPCLCLCE3MSP LC-LC OM3 Duplex Plenum Fiber Patch Cord

Overview

The Hubbell FPCLCLCE3MSP is a 3-meter OM3 duplex fiber patch cord terminated with LC connectors on both ends and rated for plenum-rated air-handling environments. This is the cable you reach for when routing between patch panels and active equipment inside a drop ceiling or raised-floor air plenum — the jacket chemistry meets NFPA 262 flame-spread requirements that standard LSZH or riser-rated cables cannot satisfy in those spaces. If your structured cabling infrastructure spans plenum ceiling pathways, substituting a riser-rated jumper is a code violation regardless of how short the run is. Browse the full Hubbell structured cabling line for complementary panels, couplers, and enclosures.

The duplex LC-to-LC configuration carries two fibers in a single jacket — one transmit, one receive — which is the standard physical layer for 10GbE (10GBASE-SR), 40GbE (when used in MTP breakout schemes), and legacy 1GbE SFP links that expect full-duplex LC interfaces. LC connectors are the dominant form factor in enterprise switching and SFP-based transceiver modules; if your switches, NVRs, or fiber media converters use SFP ports, LC is almost certainly the connector you need.

OM3 multimode fiber — sometimes called aqua fiber for its jacket color in non-plenum variants — supports 10GBASE-SR at up to 300 meters and 1GBASE-SX at up to 550 meters over 50/125µm laser-optimized glass. At a 3-meter patch length, the FPCLCLCE3MSP is sized for intra-rack or close-cabinet patching: connecting an access switch to a fiber distribution panel, linking an NVR to a core switch, or bridging two fiber-facing devices in the same rack row. For fiber optic cable assemblies on longer horizontal or backbone runs, a pre-terminated trunk or blown-fiber solution is more appropriate — a 3-meter patch cord is a termination jumper, not a backbone segment.

Key Features

• Plenum (CMP) Jacket Rating: Complies with NFPA 262 low-smoke, low-flame-spread requirements. Required by the NEC wherever cables pass through HVAC air-handling spaces — not optional. Substituting a riser (CMR) or general-purpose cable in a plenum ceiling is a code violation that will fail inspection and create liability exposure.
• OM3 Multimode Fiber (50/125µm Laser-Optimized): Supports 10GBASE-SR to 300m and 1GBASE-SX to 550m — the bandwidth headroom covers today's enterprise switching gear and gives you room to upgrade transceivers without pulling new fiber. OM3 is backward-compatible with OM1/OM2 transceivers at reduced distances.
• Duplex Configuration: Two fibers in one jacket simplify cable management at patch panels. A single duplex cord handles a full-duplex SFP link — you're not managing two separate simplex strands per port, which halves the cable count at high-density panels and reduces the chance of swapped Tx/Rx fibers during patching.
• LC Connectors (Both Ends): LC is the standard interface for SFP, SFP+, and SFP28 transceivers in enterprise and data center switching. Compact footprint allows higher panel density than SC connectors — relevant when you're managing 24- or 48-port fiber patch panels in a crowded rack.
• Secure Connector Design: The “Secure” designation in the Hubbell product family indicates a locking or retention-enhanced LC connector body. This matters in high-vibration environments or dense patch panels where accidental pull-outs cause intermittent link failures that are difficult to trace — the connector stays seated under incidental contact.
• 3-Meter Length: Sized for intra-rack or adjacent-rack patching. Long enough to route neatly through cable management arms without excess slack pooling at the bottom of the rack. For runs to a fiber distribution panel one rack bay away, 3 meters is typically the right choice; longer runs (5m, 10m) introduce unnecessary slack and insertion loss, though at OM3 distances the optical budget impact is negligible.

Integration and Compatibility

The FPCLCLCE3MSP is compatible with any SFP, SFP+, or SFP28 transceiver using an LC interface — this covers the overwhelming majority of enterprise access switches, core switches, NVRs with fiber uplinks, fiber media converters, and OLT/ONU equipment. On the passive side, it terminates into any LC-compatible fiber coupler, patch panel, or wall plate. The OM3 fiber grade pairs correctly with OM3 or OM4 transceivers (SR optics); use it with OM3-rated SFP+ SR modules for 10GbE links. It will also work with OM1/OM2 transceivers at reduced maximum distances — though in practice you wouldn't install OM3 glass just to run OM1 optics. Consult your structured cabling planning resources to confirm fiber grade consistency across a link end-to-end; mixing OM grades on a single run degrades the link to the lowest-performing segment.

For network switches with SFP+ uplink ports, pair this cord with an appropriate 10GBASE-SR SFP+ module to complete the fiber link. If your deployment includes network video recorders with fiber uplinks, verify the NVR's SFP port accepts OM3 SR optics before ordering — some entry-level NVRs ship with copper-only uplinks.

Frequently Asked Questions

Q: What does the plenum (CMP) rating on the FPCLCLCE3MSP actually mean for installation?

A: The plenum jacket meets NFPA 262 requirements for low smoke and flame spread. It is required by the National Electrical Code (NEC) any time a cable passes through an air-handling plenum space — drop ceilings used as return-air ducts, raised-floor data center environments used as supply-air plenums, etc. Riser-rated (CMR) or general-purpose cables are not permitted in these spaces and will fail inspection. If your cable route does not pass through a plenum, a riser-rated equivalent will work and is typically less expensive.

Q: What fiber type does the FPCLCLCE3MSP use, and what speeds does it support?

A: The cord uses OM3 multimode fiber (50/125µm, laser-optimized). At 3 meters, it comfortably supports 1GbE (1GBASE-SX) and 10GbE (10GBASE-SR). OM3 supports 10GBASE-SR to a maximum of 300 meters and 1GBASE-SX to 550 meters — distances far beyond a 3-meter patch application, so the fiber is not the limiting factor in a patch cord context.

Q: Is the FPCLCLCE3MSP compatible with OM4 patch panels and transceivers?

A: Yes. OM3 and OM4 are both 50/125µm laser-optimized multimode fiber and are physically and optically compatible. An OM3 patch cord can be used with OM4 infrastructure — the overall link performance will be governed by the OM3 segment (lower bandwidth-distance product), but for short patch cord applications this distinction is irrelevant.

Q: What is the difference between a standard LC cord and the “Secure” version like the FPCLCLCE3MSP?

A: Hubbell's Secure LC connectors incorporate an enhanced retention mechanism designed to resist accidental disconnection in dense patch panels or environments with physical vibration. Standard LC connectors can be nudged loose in crowded panels; the Secure variant requires a deliberate release action. This is particularly useful in high-density data center panels where adjacent cord pulls can dislodge neighboring connections.

Q: Can the FPCLCLCE3MSP be used with OM1 or OM2 fiber infrastructure?

A: Physically, yes — LC connectors are connector-type agnostic to fiber grade. Optically, the link performance will be governed by the lowest-performing fiber segment. In practice, you should match fiber grades across a link end-to-end. Using an OM3 patch cord with OM1 or OM2 backbone fiber is not recommended for new installations; the mismatch degrades available bandwidth-distance margin.

Q: Is 3 meters long enough for rack patching, or should I order a longer cord?

A: Three meters is the standard choice for intra-rack patching and adjacent-rack connections in a standard 19-inch rack row. It provides enough slack to route through horizontal cable management without excess coiling. For patch panel connections more than one rack bay away or for overhead routing to overhead cable trays, 5-meter or 10-meter cords are more appropriate.

The FPCLCLCE3MSP is one of those SKUs that looks boring on paper until you're standing in front of a failed inspection because someone swapped in a riser-rated cord through a plenum ceiling. The plenum (CMP) jacket is the entire justification for this part number over a standard OM3 LC duplex jumper — and in any building with drop-ceiling return-air plenums, it is non-negotiable. I spec this cord specifically for switch-to-panel connections in telecom rooms where the horizontal pathways feed plenum ceiling space above.

Technical Highlights:

• CMP Plenum Jacket: NFPA 262-compliant low-smoke, low-flame-spread jacket satisfies NEC requirements for air-handling spaces — the single most important specification on this cord for code compliance in commercial buildings.
• OM3 50/125µm Laser-Optimized Fiber: Rated for 10GBASE-SR to 300m and 1GBASE-SX to 550m — the fiber grade is not the constraint at 3 meters, which means this cord accommodates any SFP or SFP+ SR transceiver you drop in today or in a future upgrade cycle.
• Secure LC Connector Retention: The enhanced locking LC connector body resists incidental disconnection in dense 24- or 48-port patch panels — a real-world reliability factor in high-density fiber distribution frames where adjacent cord movements are constant.

Deployment Considerations:

• Confirm your entire fiber link uses OM3 or OM4 glass end-to-end. Inserting this OM3 patch cord into an OM1 or OM2 backbone segment doesn't break the link, but it introduces a fiber-grade mismatch that degrades the link's maximum bandwidth-distance margin and complicates future troubleshooting.
• Three meters works for intra-rack and single-bay patching. If your distribution panel is more than one rack unit away horizontally or you need to route up to an overhead cable tray, order 5-meter cords — pulling a 3-meter cord tight to reach a panel stresses the connector ferrule and risks increased insertion loss over time.

The FPCLCLCE3MSP is the right call for structured cabling deployments in commercial office builds, healthcare facilities, and education campuses where plenum ceiling returns are standard construction — any environment where a fire marshal or AHJ will be reviewing the cable plant before occupancy sign-off.
