Optical multiplexer PolyKom-300UK is designed for installation in a rack, and the simultaneous transmission of:
- 4 or 8 streams of E1;
- Traffic of Ethernet 10/100BASE-T, 100 Mbps;
- asynchronous data stream (1-port RS-232 up to 115.2 kbit / s);
one (WDM), or two Fiber Optic Cables (FOC).
Transmission speed of the optical channel is 152 Mbps.
PolyKom-300UK is a modification of PolyKom-300U. It is designed for installation in one-piece chassis 3U-15-1 (rack).
A distinctive feature of PolyKom-300UK is the ability to centrally manage SNMP and Telnet through block V-1.
This PDH solution is effective at creating a distributed network with a small capacity of individual segments and for the organization of tapoffs (the "last mile") of SDH route.
Features of equipment:
- low price;
- ability to install a one-piece chassis 3u-15-1 (rack) 19 ", 3u;
- VlAN support (frame size is up to 1916 bytes);
- event log in non-volatile memory that stores the date, time and nature of the event;
- control through the module along the seams C1 F (RS-232 using standard ANSI-terminal) and Q (SNMP);
- download of a new software from a personal computer;
- display of the current status by single indicators;
- control over the local and remote equipment;
- low power consumption (less than 3 watts);
- 5 years warranty. .
PolyKom ®-300UK provides management using a PC:
- control over local and remote equipment in real time;
- reconfiguration of local and remote devices (including loopbacks);
- view the log of the events at the local and remote equipment.
Equipment Interfaces meet the standards of ITu-T G.823, G.775, G.742, G.704, G.703, G.654, G.652, G.651.
Possible variants of optical interface:
- 1310 nm for single-mode fiber;
- 1550 nm for single-mode fiber
bidirectional transceiver 1310 / 1550 nm (WDM) for the organization of work in fiber mode.
