Hubbell DFHPCCSCSS1SM OS2 Single-Mode Duplex CS-CS Fiber Optic Patch Cord

Overview

The Hubbell DFHPCCSCSS1SM is a 1-meter OS2 single-mode duplex fiber optic patch cord terminated with CS connectors on both ends and finished in a plenum-rated yellow jacket. OS2 single-mode fiber supports long-haul, low-attenuation transmission — suited for backbone runs between IDF/MDF closets or structured cabling links where distance and signal integrity matter more than short-reach multimode economics. The 1-meter length targets patch panel to active equipment connections in the same rack or adjacent enclosures, keeping slack minimal and airflow unobstructed.

Key Features

• OS2 Single-Mode Fiber: OS2 supports transmission distances well beyond multimode limits — typically up to 10km at 10G and beyond at lower data rates — making it the right choice for backbone interconnects rather than short horizontal runs. Yellow jacket follows the TIA-598 color standard for OS2, so field technicians immediately identify fiber type without reading labels.
• CS-to-CS Connector Configuration: CS (Compact Single-fiber) connectors deliver a smaller footprint than LC connectors, enabling higher port density in patch panels and transceivers designed for the CS interface. Both ends are CS, so this cord connects two CS-port devices directly — verify your active equipment and patch panel both carry CS ports before ordering.
• Duplex Construction: Two fibers in a single assembly handle simultaneous transmit and receive paths, which is the standard requirement for full-duplex transceiver links. No separate TX/RX cords to manage or cross-connect.
• Plenum-Rated Jacket: The plenum rating (CMP) means this cord meets fire code for installation in air-handling spaces — drop ceilings, raised floors, and HVAC plenums — without requiring conduit. Buildings with open plenum airflow paths require CMP-rated cabling; using a non-plenum cord in those spaces violates NEC Article 770. If your run stays inside a conduit or equipment room, a riser-rated cord would suffice, but plenum works everywhere riser does.
• 1-Meter Length: Sized for same-rack or adjacent-rack patching — long enough to route cleanly through a cable manager without excess coiling. For longer runs or cross-aisle links, select a longer variant in the same family.

Integration and Compatibility

The DFHPCCSCSS1SM is designed for structured cabling environments where CS-port transceivers or patch panels are already deployed. CS connectors are increasingly specified in high-density data center and enterprise MDF builds where LC's port density is no longer sufficient. Confirm transceiver compatibility — CS-interface SFP/SFP+ modules are required on both ends. This cord is not interchangeable with LC, SC, or MPO-terminated assemblies without an adapter.

Frequently Asked Questions

Q: What does OS2 mean, and is this cord single-mode or multimode?

A: OS2 is a single-mode fiber standard (ITU-T G.652.D). Single-mode fiber uses a much smaller core (typically 9 microns) than multimode and supports longer transmission distances with lower attenuation. This cord is single-mode.

Q: What connector type does the DFHPCCSCSS1SM use?

A: Both ends use CS (Compact Single-fiber) connectors. CS connectors are smaller than LC connectors and are designed for high-density patching environments. Your patch panel ports and transceiver cages must be CS-compatible to use this cord.

Q: Can this cord be installed in a plenum ceiling space?

A: Yes. The plenum-rated (CMP) jacket meets NEC Article 770 requirements for installation in air-handling spaces including drop ceilings and raised floors used as HVAC plenums, without requiring conduit.

Q: Is this a simplex or duplex cord?

A: Duplex — two fibers bonded in a single assembly, providing simultaneous transmit and receive paths for full-duplex transceiver links.

Q: What is the length of the DFHPCCSCSS1SM?

A: 1 meter. This length is suited for same-rack or adjacent-rack patching. If you need a longer run, select a longer variant in the same cord family.

Marty Allison

The DFHPCCSCSS1SM is a straightforward cord for a specific job: patching two CS-port devices over a 1-meter span in a single-mode OS2 backbone environment. The CS connector is the detail that matters most here — if your transceivers or high-density panels carry CS ports, this is the right assembly; if they carry LC or SC, it is not, and no adapter scenario is clean enough to recommend for a permanent install.

Technical Highlights:

• OS2 Single-Mode Fiber: Supports transmission up to 10km at 10G (per ITU-T G.652.D) — backbone-grade fiber in a short patch assembly, which is correct when your entire structured cabling plant is single-mode and you need consistency at every connection point.
• Plenum (CMP) Jacket: The CMP rating satisfies NEC Article 770 for open air-handling plenum spaces without conduit — useful in enterprise buildings where cable trays run through HVAC zones and riser-rated cable would require additional protection.
• 1-Meter Duplex Assembly: The 1-meter duplex format handles both TX and RX in a single managed cord, reducing the chance of a crossed fiber pair during patching — a common commissioning error on high-density CS panels where individual fiber identification is harder than on LC.

Deployment Considerations:

• CS connectors require CS-compatible port cages. Before specifying this cord, confirm the transceiver module part numbers on both endpoints explicitly list CS as the connector interface — SFP+ CS variants are a distinct SKU from LC variants at the transceiver level.
• At 1 meter, this cord has essentially no slack for re-routing if rack positions shift. If there is any chance the active equipment moves to a non-adjacent slot, spec a 2-meter or 3-meter variant to avoid a recabling event.

This cord fits cleanly in a high-density single-mode MDF or IDF build where CS-interface patch panels terminate backbone fiber and CS-port transceivers connect to spine switching — specifically the short hop between panel port and switch faceplate where a 1-meter assembly is the tightest professional fit.
