Inquiry on how long maximum distance for E1 cable can run end to end.
Refer to R&D and R&D confirmed about this parameters, E1 cable 75 ohm can run maximum is 200 meter and 120ohm maximum is 300 meter and R&D said this
parameters not issued at any documents.
It the same condition for active to active and active to passive. Actually no meaning for active to passive. All connections must be active to active. Means one
equipment or device to another equipment or device.
New project need to run many E1 cables and the distance between the equipment and DDF quite long. Thus, we scared if run too long can cause signal degrade
and it will effect the performance of services.
So, we need confirmation on how long maximum distance for E1 cable can go without signal degrade for RTN 910 and RTN 950.
1. Need confirmation on maximum distance for active to active like from IDU to customer equipment.
2. Need confirmation on maximum distance for active to passive like from IDU to DDF.
1. Need to ensure cable length must not exceed the maximum distance to avoid signal degrade.
2. In case of a few E1 distance are exceed 200M (75ohm) or 300M (120ohm) use media converter, which convert from electrical signal to optical signal and the rate
still the same and the distance can go longer.
