Fiber-Span 3.3 Remote Fiber Node Detailed Description The Remote Fiber Node is a dual band duplexer/amplifier system. On the UL path, the Remote Fiber Node amplifies the RF signal (low noise amplifier) and converts it to optical. On the DL path (TX), the Remote Fiber Node converts the input optical signal to RF and amplifies the signal to 20Watts (power amplifier). Following is a brief description of each module. OP/RF Module: Converts RF to optical and optical to RF.

Fiber-Span 4.2 Fiber Transceiver Unit Detailed Description The Fiber Transceiver Unit (FTU) has two different functions: it converts the input optical signal to RF on the UL path (Rx), converts the RF input signal to optical on the DL path (Tx) and it also monitors and controls the network (FTU and RFN) via the Element manager. The FTU has two different input configurations: • Separate Tx & Rx: For low power compact base station with separate Rx and Tx signals, input power –5dBm to 5dBm.

Fiber-Span Installation Overview The flow chart below illustrates the steps required to install the DDAS Remote Fiber Node and FTU. Details and graphic explanations for the installation steps are shown in the following detailed installation sections, as indicated. Remote Node Close down the Antenna Site Isolate the power source and ensure the site is safe. Close down the BTS cell Isolate the power source and ensure the site is safe. Secure Remote Node to tower or surface, as desired.
Fiber-Span Detailed Installation Instructions Remote Fiber Node Installation The DAS Remote Fiber Node has been designed to be mounted outdoors directly on the antenna mast. If this is not feasible, it may be mounted on a flat wall surface as close as possible to the associated antenna. Each DAS Remote Fiber Node comes equipped with integrated mounting brackets which are used for either installation option .
