A wholesale bandwidth service provider sells bulk bandwidth to other communication service providers, who in turn resell connectivity services to enterprises or retail customers. Wholesale bandwidth providers include large integrated telecom operators having surplus capacity in their networks or fiber-rich utilities such as railways, electricity companies, oil and gas utilities that have significant fiber assets and right of way along railway tracks, power lines or oil & gas pipelines. In many countries, central or state governments choose to invest in building a high-capacity optical fiber network using a universal service obligation fund (USOF) and lease bandwidth to other communication service providers.

In addition, with the exponential bandwidth growth from on-demand cloud services, service providers are presented with opportunities to provide scalable and cost-effective solutions to interconnect data centers across global optical transport networks. The DCI networks must meet the increased capacity needs and provide customers with deterministic performance and quick response times. Tejas products are scalable, offer high-capacity in a low form factor, are SDN-ready and support encryption making it the right fit for DCI applications.

  • Bandwidth Scalability

    Multi-Tera switching, 200G+ DWDM networks, sub-lambda grooming of wavelengths, handling circuit or packet traffic

  • Technology Diversity

    PDH, SDH/SONET, OTN, Ethernet, FC on the client side; L0, L1, L2/L3 on the network side

  • Differentiated Services

    Range of service level agreements (SLAs) in terms of protection, quality of service and performance


Alien Wave Solution

Maximise investment in existing 10G infrastructure with a cost-effective upgrade to 100G+

Unmatched Product Flexibility

Many a times, it’s difficult to predict upfront as to what services will be adopted by the market. As a result, the optical platforms used should not be rigid and must have the necessary flexibility to continuously evolve and support an arbitrary mix of circuit and packet services ranging from 100% circuit to 100% packet or anywhere in-between. Tejas’ product architecture uses reprogrammable hardware and software modules to ensure greater reusability in dynamic network scenarios.
