Our fiber optic networks bring in efficient data transmission to corporate enterprises and other telecommunication companies that need rapid data transmission We focus on customer requirements, proposed network design and supplies solution which can meet different requirements of any business industries (Customization) together with technical supports by experienced & skilled network experts.


As our customers' businesses become more international, the need for timely communications with their overseas operations has increased. Corporate communications networks that can communicate information efficiently and reliably have become essential as the backbone of management strategy. The company’s objective is to serve clients demanding in connecting with high speed circuit into the oversea. There are 3 categories of international high speed communication circuit, under the license of International Terrestrial Cable (ITC) as well as International Internet:

Metro Ethernet (ME)

A metropolitan-area Ethernet, Ethernet MAN, or metro Ethernet network is a metropolitan area network (MAN) that is based on Ethernet standards using fiber optical as the main network to support huge data transmission in Bangladesh Metropolitan. BD Link Offers high-speed data, Internet, voice over IP (VoIP), video and other applications with flexible speeds of up to 10 Gbps. With Metro Ethernet you may be able to take advantage of your current router interface, avoiding the need to purchase additional equipment. Metro Ethernet is a cost-effective solution because it requires fewer physical interfaces, servers and routers to build your network than some other technologies, and it my allow you to use existing equipment you already have in place.

Ethernet over Synchronous Digital Hierarchy (EoSDH)

EoSDH’ is delivered using BD Link’s synchronous digital hierarchy network ( SDH), which provides dedicated bandwidth for uncompromising quality. Ethernet over Synchronous Digital Hierarchy (EoSDH) is an exceedingly high speed circuit using Ethernet technology based on SDH network which is developed from the existing technology by combining the distinctive characteristic of each technology i.e. the outstanding feature of Ethernet is its ease of usage and prevalence whilst SDH is recognized for its reliability; hence, this combined technology is suitable for users that need reliable data transmission via Ethernet connection. Customers may wish to enhance their service and traffic management capabilities by implementing their own network overlay on our Ethernet services. Transparent VLAN carriage and Jumbo Frames are supported on BD Link’s ‘EoSDH Network. Presently, the company offers EoSDH service from 2Mbps. to 10 Gbps. by combining SDH’s distinctive characteristic of reliability in service with the widespread usage of Ethernet interface whereby this technology is suitable for users that require reliable data transmission based on Ethernet connect i.e. multinationals etc. Bandwidths are available from 2Mbit/s to 10Gbit/s

Synchronous Digital Hierarchy (SDH)

SDH (Synchronous Digital Hierarchy) is a standard technology for synchronous data transmission on optical media. It is the international equivalent of Synchronous Optical Network. Both technologies provide faster and less expensive network interconnection than traditional PDH (Plesiochronous Digital Hierarchy) equipment. There is reliable control system with uncomplicated and reliable capability to transmit long distance data. There is also route protection system with the ability to switch transmission cable in the event of damage incurred to regular cable to ensure continuity and reliability of data transmission. Presently, the company offers SDH service from 34Mbps. to 10 Gbps. via fiber optic cable to diverse customer

IPLC Service (International Private Leased Circuit)

IPLC is the International Private Leased Circuit in which the company’s network, as a starting point, does connect directly to network of service providers in the oversea, and pass through the client’s terminal point by using DWDM and SDH Technology as main network. Meanwhile, the technology of SDH, EoSDH, and TDM are used for network service. These are depend on client’s demand and lease of speed by ranging from 64kbps - E1, DS3, STM1 to STM64 which provided high secure network and guaranteed in transferring speed of video and audio data with correctly and constantly. Circuits are not affected by congestion unlike overcrowded public networks, so communication is always reliable.

IPLC Service is suitable for multinational organizations, either big or small size of organization that wants to connect with the other counties as well as connecting with the international leased circuit and digital broadcasting providers of TV satellite.

Global Ethernet

Now’s the time to consider using Ethernet outside your Local Area Network (LAN). Ethernet services in the Wide Area Network (WAN) are growing in popularity for all the right reasons. The technology is quick to deploy, easy to manage and offers a cost effective way to enable your business. Therefore, users can reach to the video and audio data transmission properly, and get secure communications same as IPLC Service. Ethernet is becoming more and more important as an access technology, because of its reliability, cost-speed ratio and possibilities to upgrade. Businesses are increasingly embracing Global Ethernet services because of the enormous benefits and cost efficiency it brings. Global Ethernet is the best option for convergence layer technology to deliver unified communications. BD Link offers terminal multiplexing services to build a point-to-point SDH transmission network. . BD Link Ethernet Private Line (EPL) allows your organization to establish highly resilient network connections between your headquarters or data center and branch sites in many locations around the world. We can also provide a compact, cost effective and flexible solution to deliver multiple Ethernet channels. At the core, the SDH-based infrastructure provides an efficient long range transport vehicle for Ethernet traffic.
