Every manufacturer builds the same fiber optic patch cable -- yellow for single mode and aqua for multimode. Handle with care... plug it in... hope it survives more than a couple plug cycles.... This works great for data centers and IT installations, but let's face it... audio visual installations have a different aesthetic and performance requirement. Introducing the Black Series™ from TechLogix. These aren't your cheap-o network cables -- all Black Series™ cables are factory certified for performance and durability. And, yes, they feature black tactical jackets to ensure they blend into your beautifully wired rack. Black Series™ cables use top-graded OM4 multimode fiber to provide 10,000x more bandwidth than Cat 5e and Cat 6 network cables. Plus, they're certified to be completely immune to electromagnetic and RF interference, as well as lightning, static electricity and power surges. Plus, a military-grade tactical jacket provides flexibility and durability even when repeatedly and heavily handled. TechLogix Black Series™ cables combine the performance of fiber with the durability of a silk covered battleship. They'll differentiate your next installation and ensure it performs for years' to come.
