 Can I install Compufox transceivers on Cisco, 3Com, HP equipment without affecting the warranty of the equipment the transceivers are being installed into?

It is a misconception to think that using third party transceivers will void your switch warranty. The truth is they do not. And more importantly, it is against the law for the OEM to say it does. The Federal Trade Commission’s Magnuson-Moss Act protects consumers from this misconception! Under this act consumer warranties cannot include tie-in sales. In other words, Manufacturers cannot oblige you to buy their transceivers to keep their switch warranty valid.

 Why are Compufox transceivers much cheaper than Cisco, HP, or 3 Com?

Manufacturers such as Cisco, HP, 3Com, and many others buy their transceivers from third party manufacturers and add their logo and sticker to them and sell them at high margins.
