johansson 4000 Optical Headend

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 64 passive splits. The 4001 Optical Compact Headend converts 1 input to 1550nm optical wavelength.
