In today’s world, people demand for Triple Play services like - high speed data (HSD), highdefinition video on demand (VoD) and voice services over cable broadband. In order to meet customer expectations, CSPs must invest in the cutting-edge solutions (i.e. they need to upgrade their existing HFC network to higher frequency range). Most of the service providers prefer to increase their bandwidth from 860 MHz to 1 Ghz & 1.2Ghz by using DOCSIS 3.0 & 3.1 transmission system.

At Cyient, we have significant expertise in HFC technology. Our effective plan and design methodology and experience in HFC network design empowers CSPs to optimize their networks. Our onshore/offshore delivery model enables our clients to utilize their existing and new network infrastructure effectively, thus improving deployment, trim their project timelines, reduce their design costs, and improve their operational efficiencies.

Cyient has an expert HFC engineers’ team with excellent skillset on HFC engineering projects globally. We have also delivered complex HFC designs in Greenfield & brownfield area’s (RF- Forward & Return signals) on the HFC network with 100% accuracy.

Essential Planning, Design and Field Services


High-Level Design (HLD)

We understand our client’s network architecture technology requirements, after which we study and analyze the network to identify existing brownfield and new Greenfield sites. The next step is to create new sub-divisions for the existing landbase.

Then we carry out address validation, by referring to the client’s database or third-party information sources. During the desktop survey we study the locations, create clusters, and cluster boundaries— based on ‘homes passed’. We then define the optimized locations for fiber-optic nodes/mini-bridge/ line extenders, generating BoM/BoQ reports based on the HLD approved by the client.


Low-Level Design (LLD)

After studying the field information captured from the walkout survey, we carry out the following steps:

  • Split the feeding cables and suggest possible locations for placing amplifiers
  • Plan and distribute coaxial cable, using active and passive components
  • Calculate RF signal levels such as downstream (forward), upstream (return), considering the cable attenuation (dB/100ft)
  • Calculate LV power levels, by considering the voltage/current
  • Generate schematics with location address and signal levels (forward, return, and LV signals) at the respective section
  • Create final BoM/BoQ and trace reports, for fiber and coax cables

Walkout Surveys

During this phase, we validate the physical address and feasibility of the proposed optical node, by using GPS to capture location details. We then verify the feasibility of the construction methodology (overhead or underground) and mark it on the HLD, updating BoM/ BoQ reports with these field changes.


As-Built Records Updates

After checking the existing as-built records for changes, we update the design. We validate as-built inputs and the actual materials used against the BoM/BoQ, and generate trace reports for both fiber and coaxial from head-end to ON, to the drop.
