We offer versatile, innovative products to meet the demands of broadband T3 and fiber networks. For channelized or unchannelized T3 termination and M13 multiplexing, our T3SU products simplify T3 connectivity, while protecting critical broadband uptime. Bringing broadband closer to the network edge, our OPTI and OCU product lines include devices for point-to-point dark fiber campus connectivity, copper-to-fiber conversion, and SONET applications. The MX Series of M13 multiplexers provides carrier-class service, space-saving configurations, and is the most cost-effective bandwidth consolidation solution in the industry.
Small and flexible fiber connectivity solution that supports multiple 10/100Base-T, GigE, OC-3s, DS3s/STS1s or DS1s across a OC-3, OC-12 or OC-48 fiber link
Combining ADTRAN's Opti-6100, Opti-3 and MX platforms offers solutions for aggregating up to hundreds of DS1s into DS3s for transport over a fiber connection
Small and economical M13 multiplexer with redundancy
Economical and compact DS3 drop/insert  and DS1 cross connect for channelized DS3 and up to 16 DS1s
Cost-effective solutions for extending multiple 10/100Base-T or DSX-1 connections over exiting DS3 or DS1 copper
T1s from multiple sites can be multiplexed and consolidated across a single DS3 network connection at a central site and then provide break outs those individual T1s as needed
Multiport and flexible T3 DSU/CSU for connecting LAN, PBX or router across an unchannelized 45Mbps circuit
