Capacity Development Program on DWDM Transmission Network

Telecommunication networks today employ optical technology to transport the enormous amounts of data we consume, often across large/long-haul distances. Dense Wavelength Division Multiplexing (DWDM), a fiber-optic transmission technique, involves the process of multiplexing many different wavelength signals onto a single fiber. Each fiber has a set of parallel optical channels and each one uses slightly different “light wavelengths”. The fibers employ “light wavelengths” to transmit data parallel-by-bit or serial-by-character. DWDM is a very crucial component of optical network that will allow the transmission of data: Voice, Video, IP, ATM, and SONET/SDH respectively, over the optical layer.

 

DWDM is used in both terrestrial and subsea networks, and other scenarios, including Data Center to Data Center links. Apart from meeting high-capacity requirements, DWDM also delivers required levels of quality and security. This technology is especially suitable and cost-effective for long distance transmission, i.e., long-haul networking. 

 

Bangladesh Research and Education Network (BdREN) the National Research and Education Network (NREN) of Bangladesh, provides high-speed optical fiber network connectivity to all the Public Universities and a few of the Private Universities spanned across different parts of the country using its own state-of-the-art DWDM Transmission Network.

 

The purpose of this course is to make capacity development of NREN engineers, especially in the Design, Implementation and Operation of DWDM-based Optical Transport Network (OTN). It will use sophisticated DWDM equipment during the Hands-On Lab Activities.

 

The training will be held in blended format to save the cost and to make sure that trainees will get the maximum output from the program. The format will be as follows:

 

  • Virtual Training: to be conducted over Zoom Platform: 8 classes, 2 classes/week, 2 hours/class.
  • Physical Training: 4 days (8 hours/day), Mostly hands-on, to be held onsite at Dhaka.

 

The training is planned in a way that contains an online exam [MCQ] at the end of the “Virtual Training” program. Provided the candidate passes that exam, the candidate will be chosen for physical training. The candidate will get the opportunity to attend the exam twice. In case of his/her failure in the exam at the first attempt, he/she can take it for the second time. If the candidate fails to pass the exam in both of his/her attempt, he/she will be disqualified to be considered for physical training. However, due to limited seating capacity in “onsite” training, merit of the candidate might come into play in selecting the candidate.

 

Certificate/Award:

The successful candidates in virtual training will be awarded with a Digital Certificate.

The successful candidate in the physical training will also be awarded with a Digital Certificate.
