12. Net Optics Confidential and Proprietary 12 Competitive Analysis Very few vendors offer 1G and 10G media converters and converter Taps Net Opitcs has the market for straight 1G and 10G media converters practically to itself VSS Monitoring competes with Net Optics on the most popular Converter Taps (fiber to copper) VSS Monitoring offers a wide range of other converter Taps, but it is probably not a big enough market for Net Optics to bother with
