5.0 OVERALL CABLE CONSTRUCTION
5.1 Buffer tube
High Modulus Polymeric material.
Dimension: 2.8 mm., nominal.
Tube and fiber color code per EIA/TIA-598 or as specified by customer.
Filling compound: A non-toxic and dermatological safe antioxidant hydrocarbon based gel.
5.2 Dielectric Central strength member.
Epoxy glass rod with an up-coat of polymer (if necessary per construction).
Water swellable yarns are to be pulled in with the CSM.
5.3 Cable Core:
The cable elements are stranded around the CSM, using reverse oscillation.
Moisture Resistance: A water blocking tape is applied over the cable core to prevent water ingress and migration with a nominal of 25% overlap.
Non-wicking binder yarns are applied over the core tape.
5.4 Cable strength
Circumferential strength members are placed over the cable core and under the outer sheath.
5.5 Outer Sheath
UV Resistant Black Polyethylene. (or color per customer request)
A ripcord is applied under the outer sheath.
5.6 Cable Markings
Indent printed- REMFO 22 SERIES, FIBER OPTIC CABLE, # of fibers-SM, REMEE PRODUCTS CORP., TELEPHONE HANDSET SYMBOL, MM/YY (Month & Year of manufacture), Sequentially meter marked. Special print as required by customer.
