2. Introduction 2. Introduction 2.1. Purpose Mobile telephone systems transmit signals in two directions between base transceiver station (BTS) and mobile stations (MS) within the signal coverage area to carry voice and data traffic. If weak signal transmissions occur within the coverage area because of indoor applications, topological conditions or distance from the transmitter, extension of the transmission range can be achieved by means of an optical distributed antenna system (DAS).
3. Functional Description The unit utilizes a single fiber to support multiple bands in both the uplink and downlink directions. WDM (Wave Division Multiplex) filters are integrated in the optical modules. For the UL, a wavelength within 1546 nm – 1550 nm is used. For the DL, a wavelength of 1310 ±10 nm is used. The maximum optical output power for the UL and DL is 6.7 mW. 3.
