What problems and challenges hinder running high bandwidths between data centers?

• high cost of fiber lease
• lack of free fibers
• a large number of services to upload
• continuity of work in the event of a breakdown

What solution do we have?

A limited number of fibers, high bandwidth, a large number of services using different bandwidth and protocol, are suitable conditions to apply wave propagation systems.

• Point-Point Connection.

This type of connection is very demanding for transmission systems. Passive systems, depending on the services launched, allow transmission of up to 70 km for 10Gb Ethernet services or on a section of up to 20km for 100Gb Ethernet transmission. For higher speeds, it is necessary to use active devices with bandwidth from 200Gb to even 1.6Tb.

Another requirement between DCs is also connections for SAN networks, where we can run any number of 8/16 or even 32G Fibre Channel transmissions. Thanks to transmission systems, we can transmit Fibre Channel and Ethernet services in the same infrastructure.

• Point-to-point connection with protection

The speed of data exchange is important, but reliability and continuity of transmission are crucial. There are several ways to ensure redundancy in the network:

• Two independent paths to the Data Center.
  Thanks to this solution, we are guaranteed protection of the optical route. If the cable connecting the server rooms is damaged, the system will automatically switch services to the backup route.

• Full hardware redundancy.
  This solution emphasizes complete system security, in case of failure of any element of the system, no matter whether it is a fiber route or one of the active devices, the system will react and switch all services to the backup system.

What are the benefits of transmission systems?

• Better use of infrastructure

Is there a lack of fiber or does the lease of another generate too much cost? The transmission system limits the number of fibers to a single pair. You don't have to worry about the cost of the lease. Now your priority will be to increase the number of services and expand the network, not to fight for additional fibers.

• Saves space and resources

A single optical fiber used by a transmission system can replace many traditional fibers. This saves space and reduces infrastructure costs.

• Scalability and Flexibility

xWDM provides the scalability of your data center network infrastructure. Thanks to the possibility of adding additional channels, without the need for physical expansion, this system allows flexible adaptation to the growing needs of data transmission.

• Installation simpler than it seems

The installation of the multiplication system is reduced to the connection of elements with patchwork cords. The whole process is very fast and error-proof. You can start a passive CWDM system in literally a few hours.

• Absence of formalities

In case of expansion of the transmission system, you skip the formalities related to reporting to the UKE or preparation of the executive project.

• Security

Transmission systems make it possible to secure services on many levels. The first is to protect services against physical damage to the system, e.g. against cable damage or loss of one of the power sources. At this level, we achieve this by applying a backup route or full hardware redundancy. The second level is to directly protect the transmission from unauthorized access with layer one encryption.

• Ethernet and Fibre Channel in one fiber

If you have Ethernet services running on your network, Fibre Channel with different bandwidths, you can also use a transmission system. Systems such as CWDM and DWDM support virtually the entire range of protocols. Most interestingly, they can work in the same optical fiber.

• Creating a data center transmission system — where do we start?

We know that every company or institution is different, so we offer solutions tailored to individual needs. We start each project with a free consultation, during which we will ask you what your network looks like, what goal you want to achieve and what you plan for the future. After a 20-minute conversation, we will be able to determine what technology to use and present some of the best solutions.

The next stage is measurements. If during the consultation, we notice that for the correct operation of the system it is necessary to check the optical fiber track, then we will tell you how to do it.

Don't have the right tools? It doesn't hurt. We'll check it out for you.

• Can I rent equipment for tests?

We want you to be 100% sure that the investment in the transmission system will meet your expectations. After the consultation stage and deciding which of the presented concepts will be right for you, we have two options to check it in action.

The first is to reproduce a fragment of your network with us in the laboratory, where we can present the operation of the system, and the second is testing with you in a production environment.

• How long does it take to implement a transmission system? Who makes them?

Most solutions for connections between locations rely on passive devices that do not require power or configuration. The system is strapped by patchcords. This eliminates the need for fiber welding. That is why the installation is simple and fast enough that customers decide to start on their own.

If the system requires the involvement of a specialized engineer, then Salumanus ensures the implementation, configuration and commissioning of all designed services. Depending on the size of the implementation, it usually takes 1-2 working days.

• How much does a data center transmission system cost?

To answer this question, we need to clarify what can make up the price of a transmission system. The determination of the solution technology, the selection of devices or the creation of a connection diagram is free of charge as part of the consultation.

The costs are:

1. optical modulesppp
2. passive-patchcord devices

Optional:

1. measurements
2. implementation

As you can see, there are many constituent parts of the final amount. Here we will not give you the cost of implementation directly, but we can use some comparison. According to T-Mobile estimates, the average cost of downtime caused by an IT outage is about $88,000 per hour. (Source: https://testerzy.pl/baza-wiedzy/artykuly/ile-kosztuje-awaria-w-it)

Undertaking the implementation of a transmission system that:

1. will guarantee you safety
2. reduce the costs associated with the traditional construction of a fiber optic tract
3. will reduce the cost of expansion with subsequent transmissions only to the purchase of modules
4. Enabling more efficient use of available infrastructure
5. will allow possible encryption of the transmission in layer one

You will invest ok ¼ of the cost, which would be consumed by a failure. Estimate the transmission system for your needs.
