The modular connector design of the DECconcentrator 900 family of FDDI concentrators supports an endless combination of cable media, and the high port density versions provide the best cost-per-port in the industry. Combine these features with the ability to operate either as a standalone, rackable product or installed in the multislot Digital MultiSwitch 900 enterprise hub, and you have the ultimate FDDI solution. The DECconcentrator 900MX is ideally suited for FDDI environments that require a smaller number of FDDI ports and/or maximum cable media configuration flexibility.
