Purpose and functions: · Receiving and transmitting the exact time to one or more subscribers · Synchronization of equipment operation at the exact time · Synchronization of subscribers by time within both one and several objects, i.e. creation of a hierarchy of subscriber systems tied to a single astronomical time at sufficiently large distances · Retransmission of accurate time signals to the shielded premises of objects (basements, mines, etc.) The PARMA RV9.01 system consists of a GPS receiver and a set (from 1 to 4) repeaters.

The optical parameters of the media converter are determined by the parameters of the SFP modules installed in the corresponding slot of the media converter. The optical media converter supports working with various SFP modules with a supply voltage of 3.3 V and a data transfer rate of 1250 Mbit/s, that allows you to organize data transmission at distances from 0.5 to 120 km both over multimode and single-mode fiber in two- or single-fiber communication lines. The analogue of this media converter for the SFP module is Planet GT-705A.
