- 2. 2 INSTALLATION AND OPERATION INSTRUCTIONS INTRODUCTION Thank you for purchasing your American Fibertek MTM-100 multimode mini video transmitter. Please take a few minutes to read these installation instructions in order to obtain the maximum performance from this product. FUNCTIONAL DESCRIPTION The MTM-100 operates as half of a transmitter / receiver pair for the transmission of baseband NTSC, PAL, RS170, or RS343 video signals over a single multimode fiber optic cable. It is designed to operate with the MRM-100, RRM-100, or RRM-30 video receiver. The RRM-30 contains the electronics and optics of three RRM-100 units mounted on one printed circuit board to save space and reduce cost. The MTM-100 converts a single video input into a single FM modulated optical output using an 850 nm wavelength source. The M100 Series product is designed to operate over an optical loss budget range of 0 to 12 dB with a maximum distance of up to 2.5 km. The MTM-100 operates on 50 um or 62.5 um multimode fiber. Refer to the data sheets for detailed performance specifications. This unit is contained in a compact and rugged aluminum housing with internal dc voltage regulation. The detachable terminal block and LED indicators provide for easy installation and monitoring of video and dc power. The MTM-100 is designed for mounting as a modular stand alone unit. For a rack mounted version please see the RTM-100 or the RTM-30.
- 3. 3 INSTALLATION THIS INSTALLATION SHOULD BE MADE BY A QUALIFIED SERVICE PERSON AND SHOULD CONFORM TO THE NATIONAL ELECTRICAL CODE, ANSI/NFPA 70 AND LOCAL CODES. Mount the unit to a secure surface using #8 (3mm) hardware in four places. See the drawing at the bottom of this page for mounting dimensions. Be sure to allow sufficient room for the required minimum bend radius of the fiber cable used. POWER SOURCE THIS PRODUCT SHALL BE POWERED BY A LISTED CLASS 2 POWER SUPPLY ONLY. The unit requires a +12VDC power source for proper operation. The DC input is diode protected. Current draw is approximately 100mA maximum. In the USA and in Canada an American Fibertek PS-12 is supplied with this unit. The negative side of the power input is directly connected to ground. ANSI/NFPA 70 Class 2 wiring is recommended. POWER CONNECTION Power is supplied to the unit via a two pin terminal connector. Follow label on unit for proper orientation of +12 volt dc and ground. INPUT / OUTPUT CONNECTIONS The fiber optic connection is made via a ST connector located on the right side of the unit. The video input connection is made via a BNC connector on the left side of the unit. The video input should be connected to an appropriate 75Ω baseband video source such as a camera or a video recorder output. For optimum performance the video cables should be the shortest length of coax practical.
