Team Mission
● Develop a new interface technology to enableincreased panel density and reduced systemcost.
● Meet the requirements for an opticaltransceiver interface rather than just a cablingconnector.
● Use active component suppliers’ input todevelop an optimum solution. No cost shift toactive devices

Team Mission (continued)
● Single Mode and Multimode solution.
● Enable multiple sources of transceivers,connectors, and cable.
● Standardize optical connector through TIAand IEC

Statement of Direction
• NTT Has:
- Developed MT ferrule and MPO applications for many years
- Developed the Mini-MT connector around the small MT ferrule
- Planned future major application for two fiber connections
• NTT will provide technical data to support U.S. standardsactivity through US Conec, an NTT affiliate
• NTT has submitted the Mini-MT to IEC 86B for approval to startstandardization
• NTT is establishing multiple sources today and encouragesworld-wide supply
