250-Foot Cat8 Bulk Cable

This Monoprice Entegrade Cat8 bulk cable comes on a wooden reel and spans 250 feet in a blue PVC jacket. It uses 22AWG solid bare copper conductors each 0.60 mm in diameter. The fully shielded S/FTP construction wraps every twisted pair in aluminium Mylar film. The cable carries CMR riser and RoHS certifications.

Installers needing 40Gbps shielded runs

The cable suits data-centre and commercial builders who require up to 40Gbps over copper and EMI protection in noisy riser spaces. It is not for installers who need pre-terminated patch leads or lengths shorter than a full reel. Buyers without S/FTP termination tools should look at alternative cable types.

2GHz bandwidth over 30 metres

The decisive spec is the 2GHz bandwidth rating guaranteed for up to 30 metres of cabling. This frequency ceiling determines whether the cable can deliver 25G or 40G Ethernet in your server-grade links. If your design requires certified performance beyond 30 metres, this bulk reel will not meet that requirement.

Questions about this item

What conduit or pathway size is needed for the 250 ft Monoprice 142959 Cat8 bulk cable on a wooden reel?

The cable has a 22 AWG solid bare copper conductor of 0.60 mm diameter with a PVC jacket; allow enough conduit fill for the overall diameter and the reel dimensions when pulling.

What is the termination step installers most often miss with this S/FTP Cat8 cable?

Each twisted pair is individually wrapped in Aluminum Mylar film, so the foil must be cleanly folded back and the drain wire grounded on every jack or plug to keep the shield effective.

How long will the 40 Gbps rating stay valid on this CMR-rated Cat8 run?

The 2 GHz bandwidth and 40 Gbps speed are specified up to 30 meters; beyond that distance the cable still meets CMR fire safety but the high-speed guarantee no longer applies.
