Direction Neutral Splitter 1.8 GHz Zero Loss

The DNS -1800 ZL is a combination of Technetix’ low gain flexi-split amplifier and a 3-way splitter in one unit. It can be used as a 2-way or 3-way splitter and is optimized for DOCSIS® 4.0 networks. It prevents loss that would ordinarily have occurred in the network, so achieves the same split to the signal without the additional insertion loss that you would get from a traditional splitter. This helps with the operation of your network and gives you more flexibility when designing the rest of your network in the future.

The active splitter does not have smart functions; it is a basic zero loss splitter, consuming less than 6W and it can be used in existing networks and when upgrading to DOCSIS® 4.0. This is particularly important for Extended Spectrum DOCSIS (ESD), as the losses of the cable are higher at 1.8 GHz than at 1.2 GHz. The cable network is often split into two or more networks using directional couplers and a 2-way or 3-way splitter.

Furthermore, splitters and couplers induce a ‘flat’ loss across the spectrum, they make upstream transmissions for cable modems far more difficult at ultra-high splits. These active splitters can fully alleviate the concerns both for upstream and downstream. When a DNS-1800 ZL is used, the insertion losses are 0 dB for both the upstream and downstream path. This will give operators a significant advantage in optimizing the architecture of the network without the splitter or directional coupler loss and remove the need for amplifier respacing at 1.8 GHz.
