Page 9: 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 10: Protective Sleeve Removal/Packing
RFS INSTALLATION GUIDELINES Protective Sleeve Removal/Packing It is recommended that all assemblies are inspected and pre-tested before hanging, to do so no need to unreel the assembly. Both optical end faces are easily accessible. Use this quick instruction to unwrap and test the fiber. -
Page 11: 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 sock. - Page 12 RFS INSTALLATION GUIDELINES HYBRIFLEX cable is supplied in specific cut lengths with fully terminated and polished factory connectors. Short lengths of small HYBRIFLEX can be hoisted manually, otherwise a winch is recommended. Provide a pulley high enough on the tower to enable the HYBRIFLEX line to be raised sufficiently.

Page 13: 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 14 Minimum bend radius is the tightest bend an installer can bend a section of the cable without causing 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 •...

Page 15: 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. -

Caution! Only use approved accessories and tools. Also note: RFS HYBRIFLEX® does not require the use of grommets. Note: Hangers are sold in kits of 10 with hardware included (three options available) -
Page 17: Installation Of The Grounding Kit
Installation of the Grounding Kit RFS recommended that hybrid cable be grounded regardless of size. Recommended 3 Kits per run up to 200ft plus 1 for every additional 200ft. Although the HYBRIFLEX jacket removal tool (HTPT’s series) can be used, to avoid ripping off too much jacket the J-Strip is recommended. - Page 18 Please follow the included installation instruction carefully. For removal of the jacket we also strongly recommend the use of a manual jacket stripping tool, examples model JSTRIP-114-2 or JSTRIP-114 for 1-1/4” size. Check with you local RFS representative for other cable sizes. ▪...

The mandrel should be centered on the cable and in contact with the jacket surface (see Figure 7). 8. After the ripcord reaches the stop collar, remove the ripcord from the mandrel by running the drill in reverse.

Page 29: 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 30 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 31 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 32 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 33 RFS INSTALLATION GUIDELINES 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. Residual liquid alcohol acts as a transport mechanism for loose dirt on the end face. If the alcohol is allowed to evaporate slowly off the ferrule, it can leave residual material on the cladding and fiber core.

Swab stick One-click type cleaner... - Page 35 RFS INSTALLATION GUIDELINES Mobile operator specific optical testing Note: OTDR unidirectional measurements lead to inaccuracies when fibers with different Mode Field Diameters (MFD) are connected. The inaccuracies usually are in the form of “gainers” or “exaggerated losses”. At MFD mismatched connection OTDR backscattered light is greater or smaller, depending on the direction.
- Page 36 Note: When using OTDR, the longer the loopback the better Loopback the test result. RFS recommends a loopback of 30m (min) be recommenm used. Lookback modules may be used with power meters but not recommended for OTDR.
