Here's the optic fiber repeaters I've been trying to compare specs on:

DEC's DEREP-RA, costing $2k+.

American Photonics, Inc.'s RL6000-R001, costing about $2k.

Cabletron's "Isolan" repeater, type 1150-0, costing about $2k.

Excelan EXOS 1150-0, costing $2k+.

Canoga Data Systems' CER-802 fiber optic repeater, costing $1k+.

Hewlett-Packard, HP28645A (?), costing $??? [3 weeks & still waiting for
specs & price info, sigh].

I've also heard---2nd hand--of a Codex optic fiber repeater supposedly in
the $1k price range that I'm trying to get some definite info on.


I'm still looking for more info on some of these.  It seems that there are
some differences between them, but that's often difficult to get from the
somewhat-sparse spec sheets I've gotten from some of the vendors.  Most
explicitly claim 802.3 compliance, others spec sheets seem deliberately
vague...hence my question as to whether or not there are any real
differences between the lower-priced & higher-priced models.  Other
noticeable, useful differences include different types of LED indicators,
automatic partitioning features...and lengths of warranties.

Prices are even harder to get ahold of, and seem somewhat negotiable. I've
indicated approximate prices (quantity 2) that I've been quoted...usually
over the phone.  "Your mileage may vary" (perhaps considerably).

Minor flame: Having to deal with university procurement procedures, I must
have written price quotes to actually buy anything (and, I have to make an
honest effort to compare prices & features).  Despite repeated
requests, several vendors of Ethernet-type equipment (not just repeaters)
just won't give me written price quotes.  That's already limited my choices
on some equipment I've been buying...vendors I'd otherwise would have
bought from I'm not, simply because I can't get written price quotes from
them.
