Adventum Tight Buffer Riser Rated Drop Cable

This riser flame rated drop cable design accommodates 1 or 2 tight buffered optical fibers.  These cables are tested to Telcordia GR-20, GR-409, ICEA-640, and ICEA-596 for Indoor/Outdoor systems. Berk-Tek's Loose Tube Drop cables are available in Multimode, Single-mode, and GIGAlite fibers.

Construction

• Each DryGel water blocked buffer tube contains 1 or 2, 900 µm tight-buffered fibers.
• 3 mm Buffer Tube Diameter
• Thermoplastic Jacket Material

Outdoor Considerations

• Loose Tube cables are recommended if interbuilding conduit systems are likely to fill with water.
• Adventum Tight Buffer cables are not suitable for aerial-lashed installations.
• Riser rating allows for building riser shaft penetration without having to change cabling.

Applications
Berk-Tek's Adventum Tight Buffer Drop cables are suitable for all passive and active optical network designs requiring high speed voice, video, and data applications, including (but not limited to):
 

• 10BASE-FL
• 100BASE-SX/100BASE-FX
• ATM 155/ATM 622
• 1000BASE-SX/1000BASE-LX
• Fibre Channel 1.062/2.125
• 10GBASE-SR/SW
• 10GBASE-LX4
• 40/100 GbE

Features

• Riser ratings enable installations to go directly from outside plant through riser shafts with no transition point requirement.
• High tensile strength, crush resistant and small diameter design enable long pulls in non-dedicated conduits.
• Tight Buffered fibers are ready for direct termination, no fan out kits are needed.
• All dielectric design with Interlocking Armor available.
• Fully water-blocked core using a dry water blocking system.
• Available with new bend-insensitive single-mode fibers

Benefits

• Compact, water blocked, riser rated, flexible loose tube design with tight buffered fibers.
• Can incorporate an optional tracer wire.
• This drop cable is ruggedly designed for outside plant installation (non-aerial lashed)
• High Tensile Strength provides for greater pulling distances
• Long-term reliability improved over traditional tight buffer premises cables
• Low cable plant maintenance, ease of installation
• Reduced cable diameter, flexible, with easy access to buffer tube and fibers
