PDH Optical Multiplexer

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 fortelecommunications they have a special propertyto transport huge measures of data over the designed digital transport apparatus works under the principle ofmicrowave 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. The transmitting rate and time of data is lower in the synchronous digital hierarchy compared to the PDH multiplexer in real use.

TAK communication supplies different type of PDH opical multiplexer: 

1. n x E1 G.703 series fiber mux    

2. n x E1 G.703 series + Ethernet fiber series   

3. n x E1 G.703 series + GE fiber series, can support SNMP function.
