4 Hoisting Considerations In general power cable will handle similarly to coaxial cable, and similar installation techniques apply. All cables are individually serialized, be sure to write down the cable serial number for future reference. Prevent the power conductors from undue movement during hoisting by securing with tie ropes every 1 m (3 ft) to the hoisting line. During hoisting ensure that there is a free path and that the cable, and especially the end of the cable so it will not be snagged on tower members or other obstacles. Installation temperature range is -30 C to +70 C (-22 F to +158 F). Minimum cable bend radii can be found on-line in our ecatalog section at Maximum cable tensile load can be found on-line in our ecatalog section at CommScope Lace-Up Hoisting Grip required for power and fiber trunk installations. Hoisting Grip should be anchored to the support structure after the hangers are installed.! Power Cables weigh more than traditional coaxial cables. Be sure to follow proper hoisting and attachment procedures. Hoisting Recommendations Fiber Enclosure Box (D) (D) Grip Location Reminder: Plan grip location by measuring distance (D) from Fiber Enclosure Box to tower support member. 4

14 General Specifications RRU to Direct breakout Tails In general Hybrid cables will handle similarly to a coaxial cable. The terminated fiber ends however are fragile and must be protection during installation. Leave the packaging around the fiber ends in place until ready to make final connect of the jumper at the RRU or BBU. DO NOT BEND THE FIBER ENDS TIGHTER THAN 30 mm (1.2 in) BEND RADIUS ELSE THERE IS A RISK OF BREAKING THE GLASS FIBERS. Attach the main cable securely to the structure or equipment using hangers to prevent strain on connections from movement in wind or snow/ice conditions. Ensure the DLC fiber connector is seated firmly in RRU. Ensure the weatherproof boots for both fiber and power connections are seated firmly in the RRU. Installation temperature range is -22 F to 158 F (-30 C to 70 C).

16 Breakout Procedure After the trunk cable has been installed and you are ready to make the final connection to the OVP box follow these steps for the removal of fiber protection tube. 1 Remove electrical tape from the trunk cable and corrugated protection tube 2 While holding the protection tube straight pull the tube away from cable. 3 After you have pulled the fiber and power conductors into the OVP box remove electrical tape from the trunk cable and remove clear tube for access to all optical connectors. LC Connectors Cleaning Clean exposed connector ferrule by lightly moistening lint-free wipe with fiber optic cleaning solution (or >91% isopropyl alcohol), and by applying medium pressure, first wipe against wet area and then onto dry area to clean potential residue from end face. Clean connector ferrule inside adapter by inserting lightly moistened cleaning stick with fiber optic cleaning solution (or >91% isopropyl alcohol) inside the adapter until contact is made with connector on opposite end. Rotate cleaning stick with medium pressure in one circular motion as it is pulled away from the adapter. Repeat process using dry cleaning stick. Caution: Signal strength will be affected if end and sides of ferrule are not thoroughly cleaned. Discard cleaning sticks after each use. Do not turn cleaning sticks back and forth pressing against connector end face. This may cause scratches if large contamination is present. Always inspect connector end face for contamination after each cleaning. Clean Sides of Ferrule Clean Tip of Ferrule Clean adapter by inserting adapter cleaning stick (or fiber adapter sleeve brush) moistened with fiber optic cleaning solution (or >91% isopropyl alcohol) inside the adapter and gently pull out with twisting motion. Repeat process with a dry cleaning stick. Caution: Do not try to clean adapter with a standard pipe cleaner. The sleeve inner diameter of LC adapters is too small. Do not try to clean the adapter with cleaning stick if a connector is mounted in one side. Discard cleaning sticks after each use. Adapter Brush 16

17 All in One Cleaners Designed for cleaning the ferrule end faces of connectors Open guide cap, insert connector into guide, push the outer shell to start cleaning the connector interface, a "click" sound indicates end of a cleaning process, repeat, close cap immediately after use. Caution: Be careful not to slant the connector while inserting into the Guide cap. Do not overly exert force during insertion as this may cause damage to both the connector and the cleaner. Connector Cap Guide Part Number: FCCT - L (shown) Push Cleaner X2 Part Number FCCT MPO FCCT L Description MPO Connectors DLC & LC Connectors Inspecting There are 3 basic principles that are critical to achieving an efficient fiber optic connection: 1. Perfect Core Alignment 2. Physical Contact 3. Pristine Connector Interface Scan to view video Today s connector design and production techniques have eliminated most of the challenges to achieving core alignment and physical contact. What remains challenging is maintaining a pristine end-face. As a result, CONTAMINATION is the #1 reason for troubleshooting optical networks. Implementing the process of cleaning and inspecting before mating can reduce the time spent troubleshooting, optimize signal performance and prevent damage. Clean Inspect Is It Clean? Clean No Yes Connect! Abrasive particles (i.e. rock dust) can cause permanent damage to the interface. If interface is scratched it cannot be repaired, it would need to be replaced. 17

18 Installation Check List Double check all connections keeping sectors consistent Double check all electrical terminals are tightened Double check all Enclosure compression fittings Proper external grounding of enclosure with 6 AWG (min) to 2 AWG (max) cables Double check all outdoor RRU connections (fiber, power and connectors) are properly seated Properly support all jumpers to prevent strain on fiber during severe weather Cable serial numbers have been documented in the closeout paperwork and a copy has been left on-site Fiber Troubleshooting Clean First! Clean optical end face with appropriate all in one cleaner. Clean all connector end faces Visually inspect end face for residual dirt and damage Avoid migration of contaminations from one connector to another Check continuity by using LED or lazer light source from one end face and look for light from other end to identify any broken fiber (Do not look directly at cable with lazer source) Check end face again for cleanliness before attachment.
