This chapter describes how to install each unit and cyclical cables, along with power cabling method In detail, the chapter describes now to install shelves or handovers of each unit, Power Cabling method and Optic Cabling and RF Interface. Furthermore, by showing power consumption of modules to be installed in each unit, it presents Power Cabling budget in a simple way. Then, it describes the quantity of components of modules to be installed in each unit and expansion method. 51 BlU Installation 5.
Basically, the common part of BIU should have shelves and if should be equipped with DUMDUM fo combine and divide EXURB signals, SLUMP to supply devices with power, CPU fo inquire and control state of each module and Power Cable fo supply power from external rectifiers In addition, MD BU can be inserted and removed to provide services for desired band (Optional) 51.2 BiU Power Cabling Bl has -48Y of input power.

For optical adapter, SCAPULA type should be used. To prevent the optical access part from being marred with dirt, it should be covered with a cap during move. When devices are connected through optical cables, you need clear them using alcohol to remove dirt 5.24 Insert DOU to ODU In an ODL Shelf, up to two Odious can be installed. DOU module is in Plug in Play type. When you insert DOU in GOL, insert the unit into the left BOLT slot fest.

In addition, RDU can be inserted and removed to provide service for desired band (Optional). 5.3.2 ROU Power Cabling ROU supports both of DC4BY and ACACIA of Input power. As RPS for [C48 and RPS for ACTIVE are separated from each other, you need to select one of them in case of purchase order. RPS for DO -48Y and SPUR far AC 120V have the same configuration and capacity while each of the units uses different input voltage from each other.

Optical cables should be inserted into Optic Port outside of ROU. Using an optical slack devices in ROU, you need fo coif around one or two roll of cables to be connected with the optical adapter of OPTIC. At this ma, curvatures of the optical cable should be at least 104 to prevent Insertion logs fom being increased, Through GU, check if PD value of OPTIC is In a tolerable range 5.
Mou can insert a RDU into any slot. It is not possible to provide services with a RDU module alone; you dean to connect the module with Cavity BPF in any case.
