DESIGN GUIDE FIBER OPTIC TRANSMITTERS, RECEIVERS, TRANSCEIVERS AND SUBSYSTEMS FOR WIRELESS AND RF SIGNAL DISTRIBUTION • PCS/PCN • DISTRIBUTED ANTENNA • CELLULAR • 70/140 MHz IF • ANTENNA REMOTING • WIRELESS LOCAL LOOP • LMDS • RADAR SYSTEMS • ESMR RF ON FIBER ™ FOR WIRELESS APPLICATIONS HIGHWAY OR LONG DISTANCE BACKHAUL SYSTEMS The beauty of fiber optic transmission is its low RF loss over long distances. Anacom offers fiber optic subsystems that can transmit over 20km, 30km or more. A trunk line system can be designed using bidirectional optical taps at the antenna sites. And with the use of WDM technology, fiber usage can be reduced by half or more. WDM TRANSCEIVER Wavelength Division Multiplexing is an optical tech- nique that allows two or more optical signals to be combined onto a single fiber. WDM is widely used to reduce fiber leasing costs. In a typical sys- tem, both the uplink and down- link paths are multiplexed onto a single fiber. In advanced sys- tem designs, a third channel for uplink antenna diversity is provided–all on one fiber. WIRELESS LOCAL LOOP TRANSCEIVER New wireless local loop systems are being designed with fiber antenna distribution as a funda- mental system design approach. Systems designers are taking advantage of fibers ability to remote the RF heads and to con- solidate the modulators at a common location. The AC 206-2.5 has a flat pass band up to 2.5 GHz. Optical splitters and combiners can be incorporated for unique optical system configurations. IN-BUILDING DISTRIBUTED ANTENNA Assure reliable and ubiquitous coverage with a fiber based dis- tributed antenna system. Cost- effective fiber optic transceiver modules can be distributed throughout a building, mall, sub- way station or any location where consistent coverage is required. The head end unit can be located anywhere on the premises, as the performance of the system is maintained even over long fiber runs. WELCOME TO THE WIRELESS REVOLUTION Whether you operate in the city, in the suburbs, over long highway runs or in- building, Anacom Systems Corporation offers you a fiber optic solution that will make your wireless network work reliably and ubiquitously. Anacom’s high perform- ance, yet cost-effective rugged fiber optic transceivers give you the freedom to go far and wide, with impunity. Welcome to the wireless revolution. RFON FIBER ™ CELLULAR BAND TRANSCEIVER The AC 106 is optimized for use in the cellular band of 800 to 1000 MHz. This transceiver, as is the case with all our fiber optic transceivers, is trans- parent to the signal format or modulation technique. Higher power and high spur-free dynamic range options are available. PCS TRANSCEIVER The AC 206 is a high performance broadband transceiver optimized for PCS antenna remoting appli- cations. It provides flat bandwidth from 1700 to 2200 Mhz and a wide spur-free dynamic range greater than 100dB/Hz 2/3 . The unit utilizes advance MQW laser diode technology for stable wide tem- peraturerange performance. LNA AMP Fiber Optic Transceiver Fiber Optic Transceiver Duplexer Antenna Fiber RF in RF out RF/Fiber Optic are used between the remote antenna and the base station. The remote unit usually includes an LNA for the uplink and a linear power amplifier for the downlink. If a commonantenna is used for both transmit and receive, a duplexer ties the two paths together. TX & RX modules, DC powered FC/APC and SC/APC fiber optic connectors 19” Subrack Unit, AC powered WITH ITS BROAD BANDWIDTH AND CAPACITY FOR UNLIMITED EXPANSIONFIBER OPTICS IS IDEAL FOR TODAY ’S AND TOMORROW’S APPLICATIONS. Fiber Optic transmission is the most efficient means to transmit Wireless and RF signals. Fiber cable has a much lower signal loss, is much lighter and is much less expensive than coaxial cable. For these reasons alone, fiber optics has grown to be a significant factor in the wireless revolution. Transmitter The fiber optic transmitter converts an RF signal into an optical signal at 1.3 um.The input impedance of the transmitter is 50 ohms. The output is an optical signal whose amplitude (or brightness) is proportional to the RF voltage input. This is referred to as direct or intensity modulation. The laser diode driver circuitry utilizes optical feedback to maintain the optical output of the laser constant. An optical detector internal to the laser transmitter is used to monitor the output power and to adjust the bias current of the laser to maintain a constant average optical output. This …
