Loose tube extrusion line used for produce loose tube with 1-24 core jelly filled optic fibers, coating material can be PBT, PE etc.
Feature of loose tube extruding line:
Machine high automized, adopt IPC+PLC control, can achieve remote monitoring.
Each type cable production data can be recorded which convenient for machine operation.
Extrusion line has very low production waste.
Production efficiency very good.
Loose tube to make:

Optic fiber (G652D) used for loose tube coating line.
Cable cutoff wavelength （λcc）
Maximum Value (dB/km)
Attenuation Value at this wavelength represent post-hydrogen aging perfomance
Max.α difference (dB/km)
Dispersion Value ps/(nm.km)
1525～1575nm 1550 ≤0.02
Zero dispersion wavelength (λ0)
The attenuation in a given wavelength range does not exceed the attenuation of the reference wavelength（λ）by more than the value α
Zero dispersion slope(S0)
Polarization Mode Dispersion (PMD)

Maximum Individual Fiber
Link Design Value(M=20,Q=0.01%)
The PMD link design value is a term used to describe the PMD of concatenated lengths of fiber （also known as PMDQ).This value respresents a statistical upper limit for total Link PMD.Individual PMD values may chanqe when fiber is cabled
