Fiber Type
SM G.652.D
| Attenuation at 1310 nm | ≤ 0.36 dB/km |
|---|---|
| Attenuation at 1383 nm | ≤ 0.32 dB/km |
| Attenuation at 1550 nm | ≤ 0.22 dB/km |
| Attenuation at 1625 nm | ≤ 0.24 dB/km |
Application
Suitable for underground ducts, laying on cable trays and direct buried installations.
High protection against rodents thanks to PAMIX armored corrugated steel layer.
General Construction
Central strength member with multi loose tube structure. Each loose tube is filled with jelly compound and flooding jelly compound for water blocking. Corrugated steel tape provides high protection against rodents and improves crush resistance.
PE outer jacket protects the cable from UV radiation and prevents water penetration. Rip cords allow easier cable stripping.
Due to its construction, the cable gains excellent mechanical and temperature performance, preventing loose tube shrinking and ensuring hydrolysis resistance.
