The fiber-optic equipment of linear path of secondary Pcp level.
Primary functions:
Trunking of four-component E1 streams (2 048 Kbit/s, G.703) into the E2 aggregate stream (8 448 Kbit/s) and it’s receiving and transmitting via single- and multimode fiber-optic cable. Decimal number is UKAT.465122.002
Polycom-200 is a simple and effective solution for transmission of digital E1 streams via fiber optic cable.
Polycom-200 is designed for operation in all areas of Russian telecom network, technological telecom network and connecting lines of any purposes. Service capability, operation and control over equipment do not depend on the existence or state of equipment for formation of the primary digital channels.
Polycom-200 - provides network jitter readings in accordance with ITU-T G.823 Recommendation.
Polycom-200 – performs trunking of secondary Pcp level by positive alignment of speeds in accordance with ITU-T G.747 Recommendation.
Polycom-200 - works via optical cable on the basis of multimode and single-mode fibers with working wavelengths of 1 300 and 1 550 nm, which parameters correspond to the ITU-T G.651, G.652, and G.654 Recommendations. As a source of optical power can be used semiconductor laser or DTN, depending on the energy potential of FIBER-optic communication lines. In this equipment are used sources of optical power radiation on the "1" safety class according to IEC 825 standard.
Polycom-200 - provides acoustic alarm and indication of emergency and pre-emergency status of the equipment, as well as alarm to external devices on the "public key" joint. Polycom®-200 analyses signals of E1 joint in accordance with ITU-T G.775 Recommendation. It has a built-in system for control of joints status and linear path of the local and remote equipment.
Polycom-200 has intercom for negotiation of maintenance crew. The digital hand set for intercom is available on request.
Polycom-200 meets "the Technical requirements for equipment of digital fibre-optic line link” of Ministry of communications of the Russian Federation dd 20.03.97ã. Certificate OS/1-SP-389 dd 06.02.1998).
Features:
- the equipment can work in one-fiber mode;
- transmits up to 4 primary digital streams at speeds of 2 048 Kbit/s (E1) via one or two optic cable fiber;
- intercom with operator of remote equipment;
- Transmission of asynchronous data stream via RS-232 joint;
- Protection of receive and transmission chains of E1 joints from short circuits and overvoltage;
- low power consumption (less than 6 Watts);
- easy installation and maintenance, no adjustingt operations;
- attractive weight-size parameters;;
- 3 years warranty.
