Tight Buffered Cable Applications
- Indoor / Outdoor Applications Where Gel-Filled Cables are not Suitable
- Robust Cables for Indoor Applications where the Cable may be Subject to a Damp / Moist Environment
- Indoor / Outdoor Applications where Termination is Directly onto Conventional Connectors (w/o Pigtail Splicing)
- Suitable for Lashed Aerial, Duct, Underground Conduit and Indoor Riser Applications
Fiber Distances by Application (conventional), pre-QSFP Release
