Intel sells a 100bT card for use with Class 5 UTP cable that is FCC Class B Certified. I'm sure there are other competitive brands out there that are also Class B. Apparently, it's possible to pass.
Regards, [email protected] ---------- From: p25800 To: EMC-PSTC Subject: Ethernet Compliance List-Post: [email protected] Date: Tuesday, May 28, 1996 2:41PM We have a decision to make on one of our systems regarding 10 base T LAN cabling. It is intended to carry 10BaseT (10Mb/s) traffic, but we want to install it with the capability to upgrade to 100BaseT (100 Mb/s). The question is whether or not to use shielded cabling. We know that the industry standard in the US and in most of the world is to use unshielded twisted pair cabling (like cat 5). Because of this, most hubs, routers, etc. have unshielded, ungrounded connectors on them. We can buy shielded twisted pair cables and connectors, but obviously the shield will not be grounded when simply plugged into an ungrounded jack. The question is whether or not unshielded 10 base T or 100 base T will meet FCC\CISPR Radiated limits. The limits applicable to our product are class A FCC. Could anyone on the net offer some guidance about this issue? Thanks in advance Glen Gassaway Motorola GSTG EMAIL: [email protected]
