Optical modem PolyKom-200M is designed for simultaneous transmission of:
- 4 streams of E1;
- Traffic Ethernet 10/100BASE-T, 100 Mbit / c;
- asynchronous data stream (1-port RS-232 up to 115.2 kbit / s);
- Up to 8 derived channels (2 or 4-wired).
Via one (WDM), or two Fiber Optic Cables (FOC).
Transmission speed of the optical channel is 152 Mbps.
This PDH solution is effective at creating a distributed network with a smallcapacity of individual segments and for the organization of tapoffs (the "last mile") of SDH route.
Compatible with PolyKom-200MK.
Attention! Designs with Ethernet module out of production!
Recommended replacement: PolyKom-300U, PolyKom-300T.
Features of equipment:
- VLAN Support (frame size up to 1760 bytes);
- event log in non-volatile memory that stores the date, time and nature of the event;
- Filtering of Ethernet-traffic;
- Administration at interface of RS-232 using the standard ANSI-terminal;
- built-in intercom with remote equipment operator (Voice Channel);
- download of a new software from a personal computer;
- Display of a current state by single indicators, notification about the emergency by sound signal and by stand signaling; ("dry contacts");
- control over the local and remote equipment;
- low power consumption (up to 4 watts);
- 5 years warranty. .
Management of equipment is performed by the F joint (RS-232/USB 2.0) using any standard ANSI - terminal.
Optical modem PolyKom-200M provides comprehensive management capabilities using a PC:
- control over local and remote equipment in real time;
- reconfiguration of local and remote equipment (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.747, G.703, G.704, G.651, G.652, G.654.
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.
