Data Center Interconnect (DCI)​ ​

Data Center Interconnect (DCI)​

Data Center Interconnect (DCI) is important for carrier and OTT customer who looking to meet rapidly expanding demand for large bandwidth or extend their service to other data center. This service connects two or more data centers together over short, medium or long distances using high-speed packet-optical connectivity such as 10G and 100G.

Benefits of DCI​

High-speed, direct connection between data centers, carrier customers and cloud providers.
High scalability to meet the growing bandwidth needs of the most demanding cloud and over-the-top (OTT) applications and data services.
Supported by a protected fiber ring infrastructure, DCI has reliable, low latency and fast deployment features.
24/7 management and monitoring.

Technology Background​ Dense Wavelength Division Multiplexing

Dense wavelength-division multiplexing (DWDM) is an optical fiber multiplexing technology that is used to increase the bandwidth of existing fiber networks. It combines data signals from different sources over a two pair of optical fiber, while maintaining complete separation of the data streams and our core system is using SmartOptics.

Provisioning Details and network designed by network side protect for Hong Kong DCI

In Building fibre in most of case is the cross connect from MMR to customer rack for most of data centre scenario.

SG DCI hand off is GoIP Rack, so customers have to bear for their cross connect from their rack to our rack.
