Hubbell DFHPCLCLCF14MVI OM4 Multimode Duplex LC-LC Plenum Fiber Patch Cord, 14M Violet
Overview
The Hubbell DFHPCLCLCF14MVI is a 14-meter OM4 multimode duplex fiber optic patch cord terminated with LC connectors on both ends and rated for plenum air-handling spaces. If you're running fiber between switches, transceivers, or patch panels in a commercial MDF or IDF where airspace cable routing is required by code, this is the correct cord — it meets the CMP (Communications Multipurpose Plenum) jacket requirement without the need for conduit, and OM4 glass supports the bandwidth demands of 10GbE, 40GbE, and 100GbE links at the distances typical of structured cabling runs inside a building. Violet jacket color follows the TIA-598 standard for OM4 multimode fiber, which matters in dense patch environments where fast visual identification by fiber type prevents mispatch errors during moves, adds, and changes. For a broader look at the Hubbell structured cabling line, including panels, jacks, and fiber assemblies, the brand page covers the full portfolio.
Key Features
- OM4 Multimode Glass: OM4 supports 10GbE to 300 meters and 40/100GbE to 150 meters — well beyond what a typical intra-building MDF-to-IDF run demands. That headroom means you won't be re-cabling when you upgrade switch hardware. If you're still running OM3, moving to OM4 at patch time is a zero-cost path to higher headroom.
- Plenum (CMP) Jacket Rating: Code requires CMP-rated cable in any air-handling plenum space — above drop ceilings used as return air paths, raised floors in data centers, and horizontal pathways above or below plenum-rated ceiling tiles. This cord satisfies that requirement without conduit. Pulling non-plenum cable in these spaces is a code violation and a fire-safety risk; the CMP rating on the DFHPCLCLCF14MVI removes that concern.
- LC-LC Duplex Connectors: LC is the dominant small-form-factor connector in modern data center and enterprise switching environments. Duplex configuration (two fibers, TX/RX) is required for standard bidirectional links on SFP+ and QSFP transceivers. If your switch or transceiver uses SC, ST, or MPO, this cord does not apply — verify your transceiver's interface before ordering.
- 14-Meter Length: 14 meters (approximately 46 feet) covers most cross-connect distances inside a single IDF or between adjacent racks in a mid-size data room. It's long enough to route through cable management and still reach the far end of a standard equipment bay without excessive slack coiled at the port.
- Violet Jacket Color: TIA-598-C assigns violet to OM4 multimode fiber. In a mixed-fiber environment — where OM3 (aqua), OS2 single-mode (yellow), and OM4 may coexist in the same patch field — violet makes fiber-type identification immediate and reliable. Mispatch between OM3 and OM4 typically degrades link performance or prevents link establishment at 40/100GbE speeds.
- Duplex Configuration: Each cord carries two fibers in a single jacket, simplifying routing and reducing cable management bulk compared to running two simplex strands. For standard SFP+/SFP28/QSFP applications, duplex is the correct format — verify before ordering if your application uses a BiDi (single-fiber bidirectional) transceiver, which requires simplex cabling.
Integration & Compatibility
The DFHPCLCLCF14MVI is compatible with any LC-interface SFP, SFP+, SFP28, or SFP56 transceiver operating over multimode fiber — which covers the vast majority of 1GbE, 10GbE, and 25GbE switching deployments in enterprise and commercial security infrastructure. Common use cases include connecting a PoE switch with an uplink SFP+ port to a fiber patch panel, linking an IP network switch to a fiber backbone, or extending camera network segments across buildings where copper distance limits apply. OM4 multimode is not compatible with single-mode transceivers (OS2) — those require yellow OS2 patch cords. Always confirm your transceiver's fiber type before mixing cord types in a patch field. For broader planning around fiber infrastructure, a structured cabling overview covers backbone topology, fiber grade selection, and patch panel design considerations relevant to this type of deployment. When pairing with fiber optic cable assemblies for longer horizontal runs, this patch cord bridges the last segment from panel to active equipment.
Frequently Asked Questions
Q: Is the DFHPCLCLCF14MVI rated for use in plenum air-handling spaces?
A: Yes. The DFHPCLCLCF14MVI carries a CMP (Communications Multipurpose Plenum) jacket rating, which meets NEC requirements for installation in plenum air-handling spaces without conduit.
Q: What fiber standard does this patch cord use, and what link speeds does it support?
A: This cord uses OM4 multimode glass. OM4 supports 10GbE to 300 meters and 40GbE/100GbE to 150 meters, covering virtually all intra-building enterprise switching applications.
Q: Can I use the DFHPCLCLCF14MVI with single-mode (OS2) transceivers?
A: No. OM4 multimode fiber is not compatible with single-mode OS2 transceivers. OS2 links require yellow single-mode patch cords. Confirm your transceiver type before ordering.
Q: Why is this patch cord violet?
A: Violet is the TIA-598-C standard color designation for OM4 multimode fiber. In mixed-fiber patch environments, the violet jacket allows immediate visual identification and prevents mispatch with OM3 (aqua) or OS2 single-mode (yellow) cords.
Q: What connector type does this cord use, and is it compatible with my switch?
A: The DFHPCLCLCF14MVI uses LC connectors on both ends in a duplex configuration. LC is the standard interface for SFP, SFP+, SFP28, and SFP56 transceivers. It is not compatible with SC, ST, or MPO interfaces.
Q: Is 14 meters long enough for my rack-to-rack or panel-to-switch run?
A: 14 meters (approximately 46 feet) is well suited for connections within a single IDF, between adjacent racks in a data room, or from a patch panel to a switch across a standard equipment bay. For longer horizontal or inter-room runs, a longer cord or a pre-terminated fiber assembly would be more appropriate.
The DFHPCLCLCF14MVI is the cord I'd reach for when I need to connect an SFP+ uplink on a PoE switch to a fiber patch panel inside a drop-ceiling IDF where the airspace is plenum-rated — the CMP jacket satisfies code without pulling conduit, and the 14-meter length gives you enough runway to route cleanly through overhead cable management without buying too much slack.
Technical Highlights:
- CMP Plenum Rating: Required by NEC for air-return ceiling spaces — not optional. Using riser or general-purpose jacket here is a code violation and a fire risk. The CMP rating on this cord closes that gap without additional conduit cost.
- OM4 Multimode Glass: Supports 40GbE and 100GbE to 150 meters, so this cord won't become the bottleneck when you swap SFP+ transceivers for QSFP28 during a switch refresh. OM3 caps out at 100 meters for 40GbE — the OM4 margin matters in longer IDF runs.
- LC-LC Duplex Format: Correct for virtually all SFP, SFP+, and SFP28 optical interfaces in commercial switching. Duplex in a single jacket keeps your cable management tighter than running two simplex strands — relevant in high-density 48-port SFP+ environments.
Deployment Considerations:
- Confirm your transceivers are multimode-compatible (SR designation for SFP+ 10GbE, SR4/SR10 for 40/100GbE) before pulling this cord — single-mode LR transceivers will not establish a link over OM4 glass regardless of connector fit.
- If your application uses BiDi (WDM single-fiber bidirectional) transceivers, you need simplex cords, not duplex. The duplex format of the DFHPCLCLCF14MVI is a mismatch for BiDi setups.
This cord is well positioned for IDF closet buildouts in commercial office, education, and enterprise security deployments where plenum code compliance is non-negotiable and OM4 headroom is worth the marginal premium over OM3 — particularly in sites planning a 40GbE or 100GbE core switch refresh within the next few years.
