201ft OM1 62.5/125 Multimode Fiber Optic Cable - OFNP Plenum Surplus

​The Backstory & Engineering

This is 201 feet of legacy fiber optic cable rescued from a state of total entropic chaos. I respooled this onto a new mandrel using a custom motorized salvage rig—specifically, a high-torque corded drill secured in a bench vise. The glass is contiguous and was salvaged with mechanical precision.

​Technical Specifications

​Length: 201 Feet (Measured during respooling)

​Type: OM1 Multimode

​Core/Cladding: 62.5/125μm

​Rating: OFNP (Plenum) – This is the high-tier fire rating required for use in air-handling spaces, ceilings, and ducts. This is NOT cheap PVC-jacketed cable.

​Manufacturer: Optical Cable Corporation (OCC)

​The Operational Reality (Condition)

I am a former virologist and current shop engineer. At the moment, I am operating on a limited internal clock speed due to some recent structural "frame damage" (broken ribs/forearm crutches). Because of this, I am currently prioritizing molten metal casting and shop optimization over lab-grade optical testing.

​Has it been tested for DB-loss? No.

​Has it been laser-verified for continuity? No.

​Is it contiguous? Yes, it respooled without a break or visible kink.

​The Deal

You are buying 201 feet of surplus potential. If you want a certified, factory-sealed reel from a distributor, go pay them $600+. If you want a bargain from an engineer who currently values a clean crucible over a DB-loss test, this is your listing.

​Sold strictly AS-IS / UNTESTED. No returns. No BS.
