We provide an end-to-end portfolio of optical and data networking products covering access, metro and long-haul networks. Our products are used to build communication networks that carry voice, data and video traffic from fixed line, mobile and broadband networks over optical fibre. We offer a diverse portfolio of products based on global technology standards, which enable telecommunications networks that are used to provide mobile, internet and broadband services, primarily over optical fibre. We broadly categorise our products as optical networking products and broadband access products. Our products can be flexibly configured as CPO, PTN and DWDM products as per the Communications Service Provider's needs and traffic requirements in the telecommunications network. We offer broadband access products based on GPON technology for FTTX broadband access, wireless broadband access products based on 4G/LTE technology and enterprise Ethernet switches. We also provide intelligent network management software based on ITU standards, for easy deployment of large-scale networks. Our network management software enables unified management of our products from a graphical and web-based user interface. In addition, our products are designed to cater to the emerging trends in SDN and NF V-enabled. Our key optical networking products include the TJ1400 and TJ1600 family of products, which can be flexibly configured as CPO, PTN and DWDM products. Our TJ1400 and TJ1600 family of products can also serve as platforms for broadband access based on GPON and 4G/LTE technologies. Besides TJ1400 and TJ1600, we also sell TJ2911, TJ1400P-M, TJ1270, TJ2100 ONT products. Our TJ2911 and TJ1400P-M series of products are Ethernet switches. TJ1270 products can be deployed for multiservice aggregation in optical networks; TJ2100 ONT product can be deployed as a customer premise equipment in GPON networks. We are also developing TJ6003W products for packet switching in LTE networks.
In legacy optical networks, data and voice traffic used to be transported by multi-service provisioning platform (“MSPP”) products as digital circuits based on synchronous optical networking (“SONET”) technology in North America and synchronous digital hierarchy (“SDH”) technology in the rest of the world. As the volume of data traffic on telecommunications networks has increased due to the emergence of high-speed residential broadband services, 3G/4G mobile internet and business Ethernet services, traditional MSPP products are being displaced by three new product categories: converged packet optical (“CPO”), packet transport networks (“PTN”) and dense wavelength division multiplexing (“DWDM”) products.
Network traffic can be in the form of circuits, which are connections used for carrying voice traffic or provide fixed capacity leased lines, or in the form of individual packets of data that are used for internet access. CPO products can simultaneously support transport, processing and switching of both circuit and data traffic. Our CPO products are based on an “Any Transport Network” (“XTN”) architecture that permits the same product to smoothly transition from being a pure circuit switching configuration to a packet-circuit hybrid switching configuration, and eventually into a pure-packet configuration as the proportion of data traffic increases. This flexibility allows Communications Service Providers to optimise their network infrastructure and cost-effectively alter their network to address traffic variances and customer demands. Our CPO products are designed to support multiple circuit and data technologies such as Ethernet, OTN, MPLS, SDH/SONET and ROADM carried on a single optical wavelength or on multiple wavelengths. Our CPO products include TJ1600 and TJ1400 that are deployed in access, metro and long-haul networks. The target customers for these products are telecommunications service providers.
PTN products are used by telecommunications operators when the proportion of circuit traffic (which may be predominantly voice) in their networks is low compared to data traffic. PTN products are optical networking products that primarily transport data traffic and can also transport voice traffic by emulating it as packets of data.
Our PTN products include TJ1600 and TJ1400 that allow service providers to build PTNs with ease of operations administration, network maintenance and efficient fault isolation and fault recovery features. Our PTN products are designed to support advanced data networking technologies, such as MPLS-TP, circuit emulation and Carrier Ethernet. The target customers for our PTN products are telecommunications service providers delivering data and circuit traffic on their networks.
An optical fibre carries traffic in the form of light pulses. Through multiplexing, DWDM technology enables the transportation of multiple wavelengths of light of different colour simultaneously over the same fibre, thereby allowing large volumes of data to be transported over a single optic fibre. Advanced CPO products are often integrated with DWDM functions.
Our DWDM products are high-density and high-capacity optical networking products that have the ability to combine over 80 light wavelengths on a single optical fibre over thousands of kilometres, resulting in cost savings for our customers. Our DWDM products include TJ1600, in multiple chassis sizes and a range of line cards to deliver a variety of services and applications in metro and long-haul networks. Our DWDM products are designed to support advanced optical technologies, such as OTN, ROADM, and 100 Gbps optics. The target customers for our DWDM products are telecommunications service providers that are building high-capacity optical networks by optimising on the number of optical fibres to reduce the cost of transmission per bit.
In recent years, telecommunications service providers are deploying gigabit passive optical network (“GPON”) and long-term evolution (“LTE”) broadband access technologies to address the growing demand for high-speed mobile and fixed broadband connections in access networks. GPON based Broadband Access Products GPON technology enables optical fibre based FTTX broadband access. GPON technology complies with the standards prescribed by the ITU. GPON based broadband access comprises an optical line terminal (“OLT”) that is installed at a service provider’s exchange location, which connects multiple optical network terminals (“ONTs”) installed at the customer premises. GPON technology uses passive splitters in the field, which reduces the overall fibre requirements in a service area thereby leading to lower network costs. We have introduced broadband access products based on GPON technology for FTTX broadband access on our TJ1400 and TJ2100 ONT platforms. Our GPON based products offer both OLT and ONT solutions. Our GPON based products for OLT solutions can be offered either as a line card to be integrated into existing optical networking products deployed by a customer or as a separate product. The target customers for our GPON based products are service providers who need to deliver high-capacity fixed-line broadband services to residential customers and reliable high-speed data connectivity services to businesses.
Enterprise Ethernet switches are deployed in local area networks (“LAN”) within offices or campuses. Enterprise Ethernet switches enable inter-connection of computing devices and accurate redirection of packet traffic from source to destination devices within offices and campuses. Our enterprise Ethernet switches are TJ2911 and TJ1400P-M products that support Carrier Ethernet and Internet protocol (“IP”) features. The main target customers for our enterprise Ethernet switches are central and state government establishments including defence agencies and public sector units that are constructing campus data networks.
LTE technology enables the delivery of high-speed mobile broadband over wireless frequencies. LTE technology complies with the standards prescribed by the 3rd Generation Partnership Project (“3GPP”) of the ITU. Implementation of LTE technology is being driven by the higher proliferation of desktop and mobile computing devices to access broadband applications. LTE technology also is preferred in areas where new fibre laying is difficult due to right-of-way issues.
We are developing wireless broadband access products called eNodeB line cards based on 4G/LTE technology as per 3GPP Release 9 standards. eNodeB line cards provide broadband access from a base station to the broadband access equipment at the customer’s premises. Our eNodeB line cards work within our existing TJ1600 product or as a separate product. eNodeB line cards are meant to achieve higher mobile broadband data rates compared to the data rates achieved by products based on 3G wavelength. Multiple eNodeB line cards can be stacked in a single chassis to achieve incremental scale-up of an LTE deployment. eNodeB line cards can also co-exist and interoperate with packet transport line cards, used for optical backhaul, which is the transport of traffic from the broadband access equipment at the customer’s premise to the base station. As a result of this design, a single chassis can provide both wireless broadband access and optical backhaul, thus resulting in cost savings. We are also developing EPC (Enhanced Packet Core) products which enables packet switching in LTE networks.
The target customers for our 4G/LTE based wireless broadband access products are telecommunications service providers offering high-speed fixed wireless services to businesses, residential customers and for mobile backhaul.
We offer our customers network management software called TejNMS. TejNMS provides graphical user interface based tools that manage the fault, configuration, accounting, performance and security functions of a network. Through the adoption of standard interfaces, TejNMS offers customers a network-wide view, which allows them to configure and deploy our, as well as third party’s network elements. TejNMS is able to automatically discover network elements whenever they are implemented on a network and calculate optimised network paths for a given service, thereby enabling us to serve our customers efficiently. TejNMS serves as a single unified management solution for our complete product portfolio including both optical networking products and broadband access products.
