Hubbell DFHPCCSLCF5MM CS-LC OM3/OM4 5-Meter Plenum Duplex Fiber Patch Cord

Overview

The Hubbell DFHPCCSLCF5MM is a 5-meter, duplex multimode fiber optic patch cord terminated with CS connectors on one end and LC connectors on the other, factory-rated for plenum (CMP) environments. The aqua jacket signals OM3/OM4 multimode glass — the standard color coding integrators and data center techs rely on to avoid mismatches at the panel. If your infrastructure mixes CS-format transceivers (common in high-density spine switches and some newer SFP+ form factors) with LC-terminated patch panels or SFP modules, this cord bridges that gap without an adapter that adds insertion loss and a potential failure point.

Plenum rating matters the moment a cable route enters a drop ceiling, raised floor plenum, or any air-handling space. Building codes in most jurisdictions prohibit non-plenum (OFNR or plain jacket) cable in those pathways — using the wrong jacket is both a code violation and a fire hazard. The DFHPCCSLCF5MM carries a CMP (Communications Multipurpose Plenum) rating, meaning it meets the smoke and flame propagation requirements for air-handling spaces without conduit. That eliminates the need to pull the cable into EMT just to satisfy inspection.

Key Features

• CS-to-LC Duplex Configuration: CS connectors are gaining traction in high-density switching environments because they occupy roughly half the panel space of a standard LC. Pairing CS at the switch end with LC at the patch panel lets you run high-density transceiver ports without forcing an all-CS infrastructure refresh on the panel side — a practical compromise for phased upgrades.
• OM3/OM4 Multimode Glass: OM3 supports 10GbE to 300m and 40/100GbE to shorter distances; OM4 pushes those distances further (400m at 10GbE, 150m at 100GbE). Both are backward-compatible, so this cord works in legacy Gigabit runs and current 10/25/40/100GbE deployments. The aqua jacket is the industry-standard identifier for OM3/OM4 — easy to verify at a glance during audits or moves.
• Plenum (CMP) Jacket Rating: Code-compliant for air-handling spaces without conduit. In commercial buildings, data center hot-aisle/cold-aisle ceiling routes, and above-ceiling horizontal runs, CMP is the minimum required jacket. Specifying plenum-rated cords at procurement eliminates the field substitution problem where a tech grabs a non-plenum spare because the right one isn't on the truck.
• 5-Meter Length: At 5 meters (approximately 16.4 feet), this cord is sized for equipment room and MDF/IDF environments — long enough to reach across a half-rack or connect a top-of-rack switch to a mid-aisle patch panel without coiling excess. It's a practical run length for structured cabling home-run segments within a single cabinet row.
• Duplex Construction: Two fibers, two connectors on each end. Duplex is the standard configuration for full-duplex transceiver links (one fiber transmits, one receives). A simplex cord in a duplex SFP port will give you a silent one-way link — duplex construction here matches standard transceiver requirements out of the box.
• Aqua Jacket Color Coding: OM3/OM4 aqua is the TIA-598 standard color for 50/125µm laser-optimized multimode fiber. In mixed-fiber environments (where you might also have OM1/OM2 orange or OS2 yellow singlemode), aqua at a glance tells the next technician what they're touching. It's a small thing that prevents costly incorrect-fiber troubleshooting calls.
• Hubbell Commercial-Grade Construction: Hubbell's structured cabling line is built to commercial installation standards — consistent ferrule polish, controlled insertion loss, and return loss specs that matter in loss-budget-sensitive long runs. Patch cords from commodity sources often have variable polishing quality that creates intermittent link issues at higher data rates.

Integration & Compatibility

This cord fits any CS-port transceiver (SFP+, SFP28, QSFP breakout with CS pigtails) on one end and any standard LC-port device — patch panels, SFP modules, media converters, fiber NICs — on the other. It's compatible with all major fiber optic patch panel systems that use LC ports, including Hubbell's own panels, Panduit, Leviton, and generic rack-mount enclosures. OM3/OM4 glass is compatible with 850nm VCSEL transceivers used in virtually all multimode SFP+, SFP28, and QSFP short-reach optics.

For PoE switch-to-access-point fiber uplinks, camera-to-NVR fiber segments, or fiber runs between a network switch and a fiber patch panel in a security or AV rack, confirm your transceiver ports are CS-format on the switch side before ordering — LC-to-LC cords are the more common choice if both ends are standard LC. Consult a fiber optic cabling guide if you're planning a new structured cabling run to verify your loss budget before selecting cord length and fiber grade.

When deploying in plenum spaces alongside fiber optic accessories such as bend-radius limiters, cable managers, and patch panel blanks, ensure all ancillary components also carry CMP or CMR ratings appropriate for the pathway — a single non-rated component in a plenum return can create a code compliance issue for the entire run.

Frequently Asked Questions

Q: What does the CS connector on the DFHPCCSLCF5MM look like, and is it compatible with standard LC ports?

A: The CS connector is a compact SFP-optimized format roughly half the width of a standard LC connector. It is not directly interchangeable with LC — the CS end connects to CS-format transceiver ports, while the LC end on this cord connects to standard LC ports, patch panels, or LC-terminated devices. Do not attempt to force a CS connector into an LC port.

Q: Can the DFHPCCSLCF5MM be installed in a drop ceiling or raised floor plenum without conduit?

A: Yes. The DFHPCCSLCF5MM carries a CMP (plenum) jacket rating, which meets the NEC requirements for installation in air-handling spaces without the need for conduit. Always verify local AHJ requirements before installation.

Q: Is OM3 or OM4 glass better for my application?

A: Both OM3 and OM4 are supported by this cord. OM4 provides greater reach at high data rates (e.g., 100GbE to 150m vs. 100m for OM3). For runs under 100m at 10GbE or 25GbE, OM3 and OM4 are functionally equivalent. OM4 is the better long-term investment if you anticipate higher data rates or longer runs.

Q: What data rates does the DFHPCCSLCF5MM support?

A: The OM3/OM4 multimode fiber in this cord supports 1GbE, 10GbE, 25GbE, 40GbE, and 100GbE when paired with appropriate transceivers and within distance limits. At 5 meters, it is well within the distance limits for all of these data rates.

Q: Does the aqua jacket color have a specific meaning?

A: Yes. Aqua is the TIA-598 standard color designation for OM3 and OM4 laser-optimized 50/125µm multimode fiber. This allows technicians to identify fiber type visually without tracing cable labels, reducing the risk of connecting incompatible fiber types in mixed environments.

Q: Is the DFHPCCSLCF5MM suitable for outdoor use?

A: No. This cord has a plenum-rated indoor jacket and is not rated for direct outdoor or direct-burial installation. For outdoor fiber runs, use a cable rated for OSP (outside plant) or armored outdoor applications.

The detail that I flag on every CS-LC order is the connector asymmetry — and the DFHPCCSLCF5MM is a clean example of why it matters. The CS end is not a cosmetic difference from LC; it's a distinct physical format designed specifically for high-density SFP+ and SFP28 ports where panel space is the constraint. Mis-ordering an LC-LC cord when your switch ports are CS is a job-site delay, not a quick swap. Verify your port format before procurement, every time.

Technical Highlights:

• CMP Plenum Jacket: Code-required in air-handling spaces — this isn't an upgrade, it's a baseline for above-ceiling and raised-floor routes. Specifying CMP at order time eliminates field substitution with non-rated cable that creates inspection failures and rework costs.
• OM3/OM4 Multimode at 5 Meters: At this length, you're solidly within distance margins for 10GbE through 100GbE. Loss budget is effectively a non-issue at 5m; the fiber grade matters more for future-proofing than for current link performance at this run length.
• Duplex Construction: Full-duplex transceiver links require two fibers — Tx and Rx. A simplex cord in a duplex SFP port gives you a one-directional link that can be surprisingly difficult to troubleshoot. This cord ships duplex, matching standard transceiver requirements without any field modification.

Deployment Considerations:

• Verify CS port compatibility at the transceiver before ordering. CS is most common in newer high-density switching platforms; older SFP+ switches typically use standard LC. Mixing up the order means a non-returnable custom-length cord sitting on a shelf.
• Even in plenum-rated installations, keep bend radius above the minimum specified by the cord manufacturer. Tight bends at patch panel entry points are a leading cause of elevated insertion loss and intermittent link errors on multimode runs — a problem that doesn't always show up until traffic loads increase.

This cord is the right pick for MDF/IDF equipment room segments where a high-density CS-port switch connects to an LC-terminated fiber patch panel — specifically in commercial buildings with above-ceiling cable routes where CMP is the code-mandated minimum. It's not the right cord for outdoor segments, OS2 singlemode infrastructure, or any run where both ends are standard LC.
