The MAXI Mode Converter is used to convert multimode to single mode, or vice versa, in a variety of LAN and Telephony communication environments including PABX, Ethernet, Token Ring, FDDI, ATM & SONET (OC1 & OC3).  This conversion is done to cross-connect different fiber types, regenerate optical signals and/or extend transmission distances.



The TC3005 "MAXI" Multimode-to-Single Mode Fiber Optic Converter converts multimode formats to single mode formats, or vice versa, for data transmission up to 200 Mbps.  Transmission distances to more than 100km are possible with the Laser 1550nm option (34dB loss budget).

The MAXI will convert or repeat all popular wavelengths including 850nm, 1300nm or 1550nm over single mode or multimode fiber optic cable.  It is compatible with most communication technologies including Ethernet, Token Ring, TAXI, OC1/OC3, ATM, FDDI and SONET.

The MAXI provides users with several key features including Local & Remote Loopback, a Test Signal Generator, Dry Contact Relay Alarm, Audible Alarm Buzzer, Power Redundancy, and standalone or rackmount modularity.

The Test Signal Generator and Dry Contact Alarm are particularly beneficial.  The Signal Generator (160 Mbps) helps technicians conduct various installation tests including fiber link verifications.  The Dry Contact Alarm Relay, which includes an audible alarm buzzer, identifies Optical Signal Loss on either the multimode or single mode ends.

Power redundancy is load sharing and switches over automatically in the event of a failure.  Power can be either 12VDC (standard), 24VDC, -48VDC, or 115/230VAC with an external power cube.  Standalone versions are modular, i.e. used either in a standalone case or in a Rack Mount assembly.  Standard connectors are ST or FC type.

Four DIP switches and eight LED indicators are provided to help installation and troubleshooting.  An extreme temperature version (-20 to 70C), Model TC3005T, is also available.
