LINX doesn't rent fibers. It's a one-time (NRC) fee for 8 pairs, which are patched to any other member on the service for free for life. (Although I don't know if they promise to keep it free forever, but it's been free for many years with no mention of it changing.)
We (LONAP) don't offer PNI services, and only offer the conventional switch ports, which members normally want so that they can get access to our peering lan and swap some traffic. [www.lonap.net] All exchanges offer this connectivity model. We offer private CUG and member-to-member private VLANs, which is similar, but still passes through the switch fabric.
I believe Exchange Point offers a PNI-like service over their network.
But in general, an "Internet eXchange Provider" offers a shared switch. Anything else is really just a meet-me room. For instance, I wouldn't call Suite 1515 (formerly NYCC) an "IXP".
