Receiving and transmitting modules for electrical communication lines in SFP metal enclosures with separate optical input/output for an RJ-45 type electrical connector for data transmission over a category 5 twisted pair.

The voltmeter is capable of working both independently and as part of automated measuring systems with interfaces such as USB, RS-232, IEEE-488 (CPC). Technical specifications Measuring ranges of electrical quantities: - constant electrical voltage from 3 MV to 1000 V - SCR of alternating electric voltage in the frequency range from 10 Hz to 1 MHz (AC) from 10 MV to 1000 V - RF RF AC voltage in the frequency range from 10 Hz to 2000 MHz (RF) from 10 mV to 100 V - frequency of the measured AC voltage from 10 Hz to 1 MHz Measurement errors of electrical quantities: - constant electrical voltage ± (0.0021 - 17)% - SCR of alternating electric voltage in the frequency range from 10 Hz to 10 MHz (AC) ± (0.017 - 21)% - RF RF AC voltage in the frequency range from 10 Hz to 2000 MHz (RF) ± (0.21 - 16)% - frequency of the measured alternating electric voltage ± (0.1 -10.1)% General characteristics: Operating temperature range from 5 to 40 °C AC power supply 220 V, 50 Hz Power consumption, no more than 50 VA Overall dimensions, mm 489x91x381 Weight, not more than 8.5 kg

The module uses connectors of the SMA type. At the request of the customer, any combination of output signals is possible. When installing two amplifier modules in the above devices, the total number of output signals increases to twelve.

The built-in time scale shaper provides a pulse signal of 1 c at the output of the device. Its small dimensions, weight, power consumption, and operating time allow it to be widely used as an embedded source of high-stability signals in frequency measuring devices and complexes, telecommunications systems, navigation and communication systems. It includes a frequency binding module based on a pulse signal of 1 s from an external time scale or from a SRNS GLONASS/GPS receiver and a tunable frequency synthesizer with the ability to adjust the frequency via the RS-232 interface. The built-in binding module allows the device to be used when operating in automatic correction mode as a source of a highly stable signal with a frequency error of ± 5 · 10-12 per day.

XFP (10-Gigabit Small Form Factor Pluggable) is a protocol—independent hot-swappable optical transceiver, usually operating at 850nm, 1310nm or 1550nm wavelengths or wavelengths from the CWDM band at a speed of 10 gigabits per second in SONET/SDH, Fiber Channel, Gigabit Ethernet, 10 Gigabit Ethernet and other applications, including WDM channels.

Optical transceivers are in standard SFP metal cases with separate optical input/output for LC type connectors to transmit the signal over two optical fibres.
