Medium / light duty Breakout or Zipcord, Plenum rated (OFNP). L-com stocks a full line of this type of cable. Drop ceiling or air handling conduit Light duty Simplex or Zipcord. L-com stocks a full line of this type of cable. Medium / light duty Breakout or Zipcord, Riser rated (OFNR). L-com stocks a full line of this type of cable. Riser Shaft Heavy duty Pole to Pole, Figure 8 or round messenger cable. L-com can fabricate this cable as a custom fiber assembly. Heavy / medium duty Underground cable armoured for direct burial or breakout for inside conduit. L-com can fabricate this cable as a custom fiber assembly. TIP: Bandwidth and application differences, between copper and fiber optic cabling Type: Fiber Optic Cabling 900 Micron Tight Buffered Fiber Outer Jacket Typical Bandwidth: Typical Use: Aramid Strength Elements < 10 GHz Data communications Broadcast Most bandwidth. Fastest transmission speeds. Immune to EMI/RFI. Difficult to terminate. Most expensive cost / foot. Benefits: Limitations: Unshielded Twisted Pair Cabling (Copper) Coaxial Cabling (Copper) Outer Jacket Shielding Outer Jacket Dielectric Center Conductor 4 Twisted Pairs < 100 MHz (Cat 5E) Structured wiring in local area networks. Inexpensive, relatively easy to install and terminate. Maximum distance of 100m. Can be affected by EMI/RFI. < 1 GHz (RG6) Cable TV / Broadcast Test and instrumentation Inexpensive, relatively easy to install and terminate. Can span longer distances than UTP. Can be affected by EMI/RFI. Polish Types / Typical Back Reflection PC <-40dB Back Reflection L-com ® CONNECTIVITY PRODUCTS ULTRA PC <-50dB Back Reflection 2007 Master Catalog 1.0 Prices and specifications subject to change. 8° ANGLED PC <-60dB Back Reflection In Singlemode applications the amount of back reflection on assemblies can be critical. L-com utilizes PC or APC polish on all standard singlemode assemblies listed. UPC finishes are available by custom order.
