How does CWDM optimise network expansion costs?

The demand for bandwidth is increasing day by day. The enormous amount of data transmitted daily forces network administrators to continuously improve their infrastructure in terms of reliability, performance and capacity.

More and more, flexibility, automation and security are becoming features essential to the proper functioning of the network. Just as often, customers recognise the disadvantages associated with its current structure, especially when there are transmission delays, failures or congestion due to limited capacity.

This, in turn, raises the need to modify, expand or lease more optical channels. However, there are huge costs involved. Can they be prevented?

The answer is yes!

Let’s take a look at the following case study on how a telecom operator optimally increased the transmission capacity of its network.

Issue: Limited capacity

The existing bandwidth is not sufficient. Demand for services is increasing, new customers are coming in, and existing customers are seeing the quality deteriorating. It’s already clear: the network needs to be improved, and money is limited.

What now? The challenge arises: build or modify the network so that it transmits as much data as possible while optimising costs. But that’s not all! In order to avoid a similar problem in the future, its flexibility must be taken care of now.

Solution: CWDM deployment

CWDM technology increases network capacity while optimising the costs associated with network expansion.

It allows a multifold increase in the efficient use of existing fibre and the creation of a highly reliable and transparent transport network.

Due to its price and the functions it performs, CWDM is implemented in projects where cost plays an important role and the service provider has a limited number of optical fibers.

The purpose of CWDM implementation:

• Increase in network capacity by up to a multiple of several times
• Optimisation of costs associated with network modifications
• Ensuring easy connection to currently used devices in the network
• Enabling transparent data transmission for each type of signal
• Launching transmission for new/potential subscribers and increasing the operator’s revenues
• Preparing the network for future expansion with additional optical channels

Actions: what steps have we taken?

Implementing the new technology at the client’s site required appropriate measures.

1. Gathering data on the client’s infrastructure to prepare a technical offer accordingly.
2. Preparing several variants of the offer for the client to visualise the costs of a system that meets their current and future needs.
3. Creation of a set of good practices and guidelines to facilitate the implementation and maintenance of the system.
4. Technical support for the client during the cooperation – after-sales service.
5. Verification of the correct operation of the system.

The results? Outstanding!

• Only 7 days to implement a CWDM solution without the need for additional staff training
• 16-fold increase in network throughput
• PLN 40,000 savings on network modification compared to the average cost of leasing 16 fibres over a distance of 10 km per year
• PLN 50,000 savings from modifying the network compared to building a cable in the existing telecommunications duct
• PLN 350,000 savings related to network modification as compared to building a network from scratch

The case study cited above is a perfect example of how CWDM technology can help optimise network expansion costs.
