Product description ■Features of ROF-LINK ・Wireless signals from public broadcasting, mobile phones, wireless LAN, commercial wireless, etc. can be optically transmitted as is. ・Fiber loss: approximately 0.5db/km, which has significantly lower transmission loss than coaxial cable transmission ・The transmission frequency range is wide and the frequency deviation of transmission loss is small from 60MHz to 3GHz. *Optical fiber has no frequency deviation due to transmission loss, but it is affected by the frequency deviation of the LED modulation circuit and PDAMP. - You can easily construct long-distance transmission lines for UHF and SHF bands just like connecting coaxial cables. ・Unlike wireless transmission, it is not subject to the Radio Law. ・Since optical fiber is an insulator, it has excellent resistance to EMC (induced lightning, strong magnetic fields, noise, static electricity, etc.). ■Applications of ROF-LINK ・Long distance transmission line for dead zone countermeasure systems for public broadcasting, mobile phones, etc. (1:1 transmission) ・Medium-to-short-distance transmission lines within buildings to secure and expand the area of wireless LAN and WiMAX systems (1:N transmission) ・Signal transmission path related to measurement equipment that requires isolation "Optical isolation AMP etc." Product features ■ROF141 (E/O+O/E) set Main functions: ROF142 (E/O) single item, ROF143 (O/E) single item ■Example of typical wireless system that can transmit data Main functions: Compatible with public broadcasting (DTV, CSTV, BSTV, FM radio, etc.), mobile phone wireless LAN, WiMAX, and various other commercial wireless systems (If you are using it for a commercial wireless system, please check the modulation method of the system. Please consult)
