The user that own a business can use this system to connect they office to one and another.The user commonly use this system because it is cheaper than SONET/SDH(Synchronous Digital Hierarchy) or PDH (Plesiochronous Digital Hierarchy) that acquit an interface of the same bandwidth. SONET/SDH is known as a standard protocol that manoeuver a multiple digital bit streams over optical fibre apply a laser or highly coherent light. PDH is a engineering science use in telecommunication network to transp ort a large quantity of that also use optical fibre and also microwave intercommunicate system.The Technology ApplicationMetro E is commonly use in metropolitan city. It being use for businessman to connect their office to one and another. many another(prenominal) Ethernet services allow the user to network their business in ways that either more complex or impossible with the alternative services.
