Optical modules SFP xPON are capable of operating at a data transfer rate of up to 2.5 Gbit/s and are used in gigabit passive optical networks.

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.

Optical transceivers are available in 9-pin plastic cases with a combined optical input/output for SC type connectors.

Appointment For use in measuring: · capacitance and tangent of the dielectric loss angle of high-voltage insulation (capacitors, inputs, transformers, insulators) · characteristics of partial discharges of liquid dielectrics in laboratory and field conditions, complete with an insulation parameter meter (for example, PARMA TENSOR-2)

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.

SFP+ modules are used to organize high-speed duplex channels with data transfer rates up to 10 Gbit/s. WDM SFP+ optical transceivers are designed to organize a duplex communication channel in a single fiber. CWDM SFP+ allows you to organize 10 Gbit/s channels in passive CWDM systems.
