Infrastructural data transfer
The data transmission capacity of optical networks may be multiplied by means of CWDM and DWDM technologies. These solutions also facilitate multiplexing, i.e. the independent parallel transmission of multiple data streams of various speeds and protocols (Gigabit Ethernet, 10GE, Fibre Channel, etc.) using the same optical fibre. These technologies transmit data streams as individual wavelengths that are joined, split and processed by active or passive WDM components. DWDM systems provide for transmitting a significantly higher number of channels compared to CWDM, also supporting transmission at higher speeds (100 G) and larger distances (several thousand kilometres). DWDM is often preferred over the otherwise cheaper CWDM solution because of these latter features (and not necessarily due to the higher number of channels). In the case of DWDM, channel spacing, i.e. the difference between wavelengths, is so small that it may be expressed only in fractions, so it is referred to in frequency values. The most frequently used channel spacing these days is 100 GHz, but 50 GHz and even denser spacing solutions are also available. Accordingly, the number of channels depends on the spacing applied. A single fibre pair is able to handle as many as several hundred independent streams. DWDM components may be used for both active and passive solutions.
MLLI - Internet leased line
The service is based on a leased line or layer-2 Ethernet technology, most often used in the following cases:
- Two sites of a company need high-speed, specific point-to-point connection to serve a particular application safely, at a guaranteed, flexibly adjustable bandwidth.
- A virtual private network is established combining the company’s own IT background (devices, experts) and the data transfer service bought from the telecommunication provider.
Benefits of the service
- Excellent quality at competitive prices
- Highly reliable managed service
- Dedicated capacity
- MPLS (a flexible and cost-efficient solution for providers aiming at excellent IP VPN services in guaranteed quality for their clients in Hungary or the Central and Eastern European region)
International leased line
The service is based on a leased line or layer-3 Ethernet technology developed for providers wishing to join the Central and Eastern European region. Invitech’s continuously developing, centrally located optical core network facilitates the fast, safe and cost-efficient establishment of trans-European connections. International leased lines provide complete services from high-speed POP-to-POP to End-to-End connections with narrower bandwidths, both within and beyond the Central and Eastern European region.
