FDDIconcentrators
The modular 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, rackmount, or installed in the MultiSwitch 900 chassis, you have the ultimate FDDI solution.
The DECconcentrator 900 devices are available in three models:
- DECconcentrator 900MX
- DECconcentrator 900FH
- DECconcentrator 900TH.
The modualr front panel ports (PMDs) are available in MMF, SMF and UTP. These can be factory or customer installed.
