Page 3: Introduction To Hybriflex
HYBRIFLEX combines optical fiber, power and alarm wire in a single jacketed cable and can connect multiple RRHs with a single feeder. Standard RFS CELLFLEX® coaxial cable accessories may be used with HYBRIFLEX cable. Both pre-terminated and on-site terminated options are available. The rugged jacket and copper wrapped armor facilitates easy transportation, handling, and installation.

Page 5: Transporting, Shipping And Handling The Drum
RFS INSTALLATION GUIDELINES Transporting, Shipping and Handling the Drum Drums must be handled carefully to avoid any damage to the drum and/or the hybrid cable.  If the drum will be shipped by van or truck the drum must be secured against rolling. Pay special attention to careful loading and unloading.
Page 6: Hoisting/Pulling Hybriflex Cable
RFS INSTALLATION GUIDELINES Hoisting/Pulling HYBRIFLEX Cable  Note: when hoisting and pulling HYBRIFLEX always use caution.  Do not remove the protective sleeve. If it is removed during pre-testing, re-attach securely before hoisting the cable.  Do not attach the hoisting grip over the protective sleeve.
Page 7: Hybriflex Bending
RFS INSTALLATION GUIDELINES HYBRIFLEX Bending  The minimum-bending radius should be strictly observed. [See product spec sheet]. HYBRIFLEX cable should be bent manually with a force applied in a distributed manner, pressing carefully while the hand slides along the cable [see diagram 1]. Avoid rapid, sharp motions.
Page 8 • performance degradation and/or damage. Refer to product data sheet for specific hybrid cable bend radius. RFS specifies two types of minimum bending radius for a cable. Single bend – irreversible minimum bend section of the cable • Repeated bend – reversible minimum bend section of the cable •...
Page 9: Fixation/Mounting Of The Cable
Crush resistance may vary for different outer materials. This should be considered when tightening the clamps (especially if these clamps have not been approved by RFS). Several different clamps may be used, we recommend using the SNAP-IN type. The SNAP-IN is suitable for all fixing situations while at the same time it is a safer clamp (less chance of failure) offering many advantages.
Page 10 Top installation within a monopole should ONLY be considered if tower loading is extremely light or • this is the first cable in a Greenfield site. Also, RFS recommends assessing the exit port size for viability of cable exiting without excessive stress on fiber connectors and brake outs. Please refer to the Monopole –...
Page 11 (This is based upon adequate sizing of the Exit Port. The main breakout is approximately 6.5 inches. Secure all unused terminations to prevent future damage.) Ground the hybrid cable on the top and bottom with RFS grounding kits. HYBRIFLEX ®...
Page 12 Have a crew member control the rotation of the reel. Short lengths of RFS hybrid may be shipped in boxes. The cable should be unboxed and uncoiled along the ground away from the tower before it is hoisted.
Page 13 RFS INSTALLATION GUIDELINES Regardless of the calculated distance, the hoisting grips should be clamped at a minimum of six inches (6”) below the breakout. Do NOT attach the hoisting grip over the fiber termination protection regardless of whether it utilizes sleeves or bags! Use a tie back rope or additional electrical tape if needed to prevent any stress or force to the fiber and protective sleeve (only use lace-up type hoisting grips).
Page 14: Fiber Inspection
RFS INSTALLATION GUIDELINES Fiber Inspection Optical Interface Connectors The interface optical connectors for mMIMO are D-LC to D-LC. An in-line weather resistant LC adaptor (ODVA) is used to mate the top jumper with the main Riser to the RRH (mating RRH connector MPO/MPT).
Page 15: Fiber Cleaning Introduction
RFS INSTALLATION GUIDELINES Fiber Cleaning Introduction Warning: Before attempting to clean or inspect fiber optics it is strongly recommended that the technician have a good understanding of the IEC 61300-3-35 fiber optics standard procedure. This document can be obtained simply by performing an internet search for IEC 61300-3-35.
Page 16 RFS INSTALLATION GUIDELINES  Always keep a protective cap on unplugged fiber connectors.  Always store unused protective caps in a re-sealable container to prevent the possibility of the transfer of dust to the fiber. Locate the containers near the connectors for easy access.
Page 17 RFS INSTALLATION GUIDELINES Inspect the connector. 6. If the connector is still dirty, clean it with a wet cleaning technique followed immediately with a dry clean to ensure no residue is left on the end-face. Note: Wet cleaning is not recommended for bulkheads and receptacles. Damage to equipment can occur.
Page 18 RFS INSTALLATION GUIDELINES  For manual advance cleaners, pull on the cleaning material from the bottom of the device until a new strip appears in the cleaning window, and then go to step 5. 5. Hold the Ferrule tip lightly against the cleaning area and rotate one quarter turn.
Page 19 RFS INSTALLATION GUIDELINES Wet Cleaning Technique: Lint-Free Wipes If a dry, cleaning procedure does not remove the dirt from the fiber end-face, then precede the wet cleaning method. Caution: Improper cleaning can cause damage to the equipment. The primary concern with the use of isopropyl alcohol is the ability to remove any residue completely from the connector or adapter.

Page 29 RFS INSTALLATION GUIDELINES 3. Insert the exposed red and black wires from the jumpers through the Y-Splice connector assembly. 4. Stagger the two red wires 2 inches beyond the corrugated tube and the two black wires 6 inches beyond the corrugated tube.
Page 30 RFS INSTALLATION GUIDELINES 7. Assemble the 2-inch corrugated conduit over the splices and over the tube from the Y-Splice Connector by 1 inch. 8. Make sure the entire 4AWG jumper and 6AWG pigtail are inserted by at least 1 inch into the mating corrugated tube.
Page 31: Hybriflex Tower Accessories
RFS INSTALLATION GUIDELINES HYBRIFLEX Tower Accessories No new accessories are needed for mMIMO application. All existing RFS accessories can be use on RFS hybrid cable assemblies. Helpful Tip: Accessories may be kitted with the hybrid assembly upon request. RFS recommends its accessories be used to avoid any incompatibly issues that may arise during the installation process.
