1. INTRODUCTION
Product description
The 4000 Optical Compact Headend converts 2 wideband satellite inputs into 2 wavelengths
(1310nm –1330nm) and puts them on 1 optical feed. The output signal is strong enough to
support huge installations, with up to 128 passive splits. The 4001 Optical Compact Headend
converts 1 input to 1550nm optical wavelength.
