The Wisi OPTOPUS is a high density optical platform with advanced management features and is broadly divided into three main areas of architecture.

HFC (hybrid fibre coax) is the optical trunk link between a conventional RF modulated Head End with a 1310nm optical transmitter feeding multiple points of reception with conversion back from light to RF for ‘last mile’ distribution over coax. See type numbers LX11, LX12 and LX21 series products.

RFoG (RF over Glass) uses a PON (passive optical node) and transmits optical signals deep into the network using the benefits of 1550nm and offers ‘Fibre to the Building’ or preferably ‘Fibre to the Home’. Key to this architecture is to retain, upgrade or offer DOCSIS and provisioning services to the user. Extended bandwidths upstream and downstream over a single fibre using optical amplifiers and higher power output levels characterize these equipment ranges. The comparatively simple network we offer to carry our conventional TV services has now become a modulated data highway.

RF Overlay is an extension of the RFoG PON method. By using the more sophisticated Course WDM or Dense WDM light frequency modulation schemes considerably more data can be carried than the conventional ‘Wave Division Multiplex’ methods more usually associated with RFoG. Now we have added high speed train tracks alongside our new highway!

Optopus hardware consists of the LX50 4 U high, 14 module back frame into which any of the ‘passive module cooling’ LX transmitters or receivers can be fitted and hot swapped, whilst the LX52 1 U high , 2 module back frame suits a lower density or outlying location option. PSU redundancy is offered in both frames and management SW offers functions such as the automatic switching between modules in the event of outages. A range of LR compact case optical receivers and transceivers are available in ‘value line’ and ‘micro line’ housings.
