Description

CAT8.1 Bulk Ethernet Cable, 40G CMR, 23AWG Solid Copper, Dual Shielded S/FTPDescription Our S FTP shielded CAT8. 1 bulk Ethernet cable is ideal for indoor short runs up to 30 meters in length. Primary application is for high performance data centers. Composed of four individually shielded pairs of 23 gauge solid bare copper conductors, with an overall tinned copper braid shield. The CAT8. 1 bulk Ethernet cable has an overall CMR Rated jacket and sequential footage markings on the jacket so you always know how much it left.

Description

Our S/FTP shielded CAT8.1 bulk Ethernet cable is ideal for indoor short runs up to 30 meters in length. Primary application is for high performance data centers. Composed of four individually shielded pairs of 23 gauge solid bare copper conductors, with an overall tinned copper braid shield. The CAT8.1 bulk Ethernet cable has an overall CMR Rated jacket and sequential footage markings on the jacket so you always know how much it left.

This CAT8 bulk cable is suitable for 25G networking but has the ability to reach up to 40G speeds. This cable has a conventional 4 pair, 8 conductor wiring configuration. These twisted pairs are individually shielded in order to repel electromagnetic interference (EMI) in electrically noisy environments. They also keep Alien Cross Talk down to prevent from slowing down transmission speeds. Shielding is a vital part of how fast the signal seed is in CAT8 cables. That is why it is important to test the continuity of your shielding to ensure no loss is occurring. This Cat8.1 cable is sold on a wooden spool of 500 or 1000 feet.

What sets CAT8 version 1 apart from CAT8 version 2? First CAT8.1 is backwards compatible with the Class I standard RJ45 while CAT8.2 is designed to be compatible with Class II Fa standard connectors. While we still recommend our CAT8 Modular plug to be used with this cable it is compatible with legacy connectors. The structure is also different in the CAT8.1 compared to the 8.2. There is far more shielding and insulation in the 8.2 to reduce interference even further if meeting the max frequencies.

Our solid CAT8.1 cable has individually shielded pairs (S/FTP), and is quality manufactured to meet and or exceed product certifications which uphold to the new ANSI/TIA-568C-2.D standards.

Additional Information

The Difference Between CAT8.1 and CAT8.2

The international standards ISO and IEC have designated two cabling variants to support 25Gbps and 40Gbps; they are Category 8.1 and Category 8.2. Category 8.1 components are used to construct Class I links which are backward compatible with the RJ45 connector interface for categories 6A, 6 and 5e this is stated in ISO/IEC 11801 and EN 50173. Category 8.2 components are used to construct Class II links. Category 8.2 components are backward compatible with components used to construct Class F and Class FA links. Category 8.2 connector interfaces ARE NOT BACKWARD COMPATIBLE with standard RJ45 jacks of existing cabling. Don't worry we offer the top CAT8 RJ45 jacks in the industry.

Great wrestle or chewing toy for your pet.
Color: brown1
My 4 legged "little boy" loves to play, even at 10 years old but is getting a tad "over the hill" for chasing a ball. This toy has brought him (and me) many hours of fun as it can be played with in the house without chance breaking something (it is soft) and was fairly well thought out - being made with the "squeeker" in one end, and a couple of ropes sewn in to provide a "tug of war" when he is really feeling frisky. I've had it around 6 months and it has only incurred minor damage and really just normal wear and tear considering what it has gone thru. A great toy for the price that your pet may play with by itself, or one you can use to wrestle with it so you can be part of the action. When this one is finally torn apart, I will be buying another one (if the dog out lasts it), or I will bury my pet with this one if it out lasts him. It's that special.

Dog toy for heavy chewers
Color: brown1
This is pretty durable. My puppy chews up most stuffed toys. This one is still mostly intact. It’s missing one ear and the tail but the way it was sewn it’s still very usable. It’s one of his favorite toys

Great dog toy! Good quality!
Color: brown1
Great quality dog toy! The rope is thick and not easy to break. Fun toy for my medium-sized dog who loves to tug-of-war with me.
