PDH

FlexCom develops and manufactures a wide range of telecommunications equipment.

PDH PDH PDH

The plesiochronous digital grading (PDH) is a basic Ethernet cable that comes under the category of high speed date transceiver process. This cable is actually frame worked with fiber optic materials and works with the means of fiber cable signals. This Ethernet cables are used in domain of information technology meant for telecommunications they have a special property to transport huge measures of data over the designed digital transport apparatus works under the principle of microwave radio systems. The name PDH multiplexer is actually fixed for this cable as it has a property of sending any larger data content but within shorter range of distances. As this cable apparatus and installation perhaps costs about value in crores. Thus these cables are most commonly used in giant IT companies and by different governments to send some highly confidential data.

There are some other techniques that also use fibre optic technique and material for transporting the data like PDH but with slight modifications. The technique synchronous digital hierarchy were introduced by the hardware developers but resulted with low efficiency than PDH.

FlexOPT – PDH-multiplexers: STM1-1 fiber converter, V.35/E1/RS485 fiber modem, E1/2E1/4E1/8E1/16E1 (120 ohms/75 ohms), 1+1 PDH fiber optic multiplexer, nxE1+1/2/4ETH optical multiplexer, 4U/6U chassis, optical multiplexer of the phone; card embedded or stand-alone in a mini-rack or 19-inch rack; dual fiber/single fiber with SC/FC connector; 220V/110V/48V power supply or both power sources simultaneously; transmission range up to 120 km. FlexOPT PDH multiplexers are E1 point-to-point optical transport equipment. The highest throughput is 16E1. The N*E1 PDH fiber optic multiplexers use PDH fiber data transmission technologies. The 1+1 redundancy scheme is supported, including through E-Band radio transmission systems, to which it is connected via an optical port. The 2M (E1) interfaces can be directly connected to a heat exchanger, a light loop device and a multiplexer to form a micromini or a special network. Full alarm function for N*E1 PDH fiber

FlexCOM AG offers a wide range of modern solutions for accessing the E1 PDH Multiplexer network. The FlexCOM OPT 4500 E1 multiplexer is used to interconnect legacy voice and data networks, provide and manage bandwidth at the E1 channel layer, as well as at the 64 Kbit/s, DS-0 time interval level, and can also be used as equipment for digital access cross-connection. This solution also offers 4 binary command telesecurity interfaces (110V DC/220V DC) to provide remote protection and IEEE C37.94 optical ports (MM/CM) to provide remote/differential protection.
