The Securities Appellate Tribunal (SAT) quashed an order passed by the market regulator Securities and Exchange Board of India (Sebi) against the National Stock Exchange (NSE), former top executives Chitra Ramkrishna (pictured), Anand Subramanian and others in the ‘dark fibre’ case.
- In the dark fibre case, certain brokers allegedly exploited the exchange’s internet infrastructure to get faster connectivity to its co- location facilities.
- The case relates to the alleged differential access given to certain broking firms in the form of ‘dark fibre’ at NSE, to connect across the colocation facilities before other members.
- The dark fibre or unlit fibre, with respect to network connectivity, refers to an already laid but unused or passive optical fibre, which is not connected to active electronics/equipment and does not have other data flowing through it and is available for use in fibre-optic communication.
