A series of modern intelligent relay protection, automation and alarm units PARMA IED-EP+ is designed for use in networks with a voltage from 6 to 750 kV

USVI(PMU) functionality: · Supports computing and data transmission in on-line mode via the C37.118-2011 protocol · have two built-in Ethernet interfaces for connecting to the LAN of the installation object · save data for later access via FTP – off-line mode

SFP+ Direct Attach Cable manufactured by Optronic is a passive Twinax cable with a length of 1 to 5 meters, the operating data transfer rate is up to 10 Gbits. SFP+ DAC are compatible with Ethernet equipment of such brands as Cisco, Extreme, Juniper, HP, Dell, Force10, Huawei, Dlink, etc.

Optical transceivers are in standard SFP metal cases with a combined optical input/output for SC, LC connectors for transmitting a signal over a communication line - one optical fiber.

CFP Transceiver models and modifications

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 media converter supports working with various SFP modules with a supply voltage of 3.3 V and a data transfer rate of up to 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-805A.

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.

A media converter is used as a converter that converts one signal transmission medium into another. The data transmission medium means optical and copper cable. The scope of application – FastEthernet and GigabitEthernet protocols, STM-1 and STM-4. Media converters are characterized by a number of parameters, by setting that you can choose the optimal network equipment for solving a specific task. The possibility to control the device; Installation location; Properties of the optical receiver-transmitter; Supported transfer rate.

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.
