Operator’s Manual EMS Wireless EkoLink Plus Fiber Optic DAS The EMS Wireless laser products are used in optical fiber communications systems for radio frequency and microwave frequency analog fiber optic links. In normal operation, these systems are fully enclosed and fully shielded by the hermetically sealed laser metal package. Laser bias current is limited by the internal control circuitry. The transmitters are coupled to glass fiber and have 1310/1550 nm optical output wavelength with typically 0.
EMS Wireless EkoLink Plus Fiber Optic DAS Operator’s Manual Handling the EkoLink Plus 1. Use ESD (electrostatic discharge) precautions when dealing with the modules within the EkoLink Plus so that units are not damaged. 2. Opening any module voids the warranty. 3. Modules cannot be "hot-swapped" (removed while unit is in operation). Disconnecting any component within the EkoLink Plus when powered can damage or destroy the equipment and will void the warranty.

EMS Wireless EkoLink Plus Fiber Optic DAS Operator’s Manual 1.0 GENERAL INFORMATION The EkoLink Plus Fiber Optic Distributed Antenna System (DAS), provides excellent signal coverage of most all large buildings, multiple buildings, airports, convention centers as well as large outdoor environments such as university campuses, rural stretches of highway, etc. With the correct selection of equipment, this can include a combination of outdoor and in-building coverage for multi-building office parks, etc.
EMS Wireless EkoLink Plus Fiber Optic DAS Operator’s Manual with one system. At Cellular 800 MHz, A + A’ + A” or B + B’ extended band segments can be covered with one unit. • The EkoLink Plus system will support up to four remotes per hub or two remotes with the diversity receive option. Diversity receive is accomplished by processing an additional receive signal (using a second receive antenna) at a particular remote unit. This signal is sent via fiber optic cable back to the hub unit.
