Multiservice terminal fiber optical multiplexer PoliKom-300U-1GT intends for simultaneous transmission:
- 1, 2, 4, 8 or 16 streams E1;
- Ethernet 2x10/100/1000 Base-T, 2x100 Base-FX / 1000 Base-X (SFP) traffic;
- asynchronous data (1 port RS-232, up to 115 Kbit/s, 1 port RS-485, up to 115 Kbit/s).
|
by one (WDM) or two fiber optic cables (fiber optic connection line).
The bit rate by optic cable is 1.3 Gb/s.
The equipment can be given for tasting: to download the blank (zip)
The main features of equipment are:
- opening of the ports E1 with licensed keys;
- plug-in modules (SFP);
- VLAN supporting (frame size up to 1632 byte);
|
- session log saving date, time and character of events in nonvolatile;
- loading new software support by PC;
- indication states of device by means of LED, and indication of alarm by beep;
- possibility to check local and remote equipments;
- power’s reservation (autodetermination/autoswitching);
- low power consumption (lower than 8 W);
- length of warranty is 5 years;
- compatibility with PolyKom-200U-1GT.
Control of device is realized by means of:
- F-port (RS-232/RJ-45) with ANSI;
- Q-port (Ethernet 10/100 Base-T) SNMP-protocol v.1.0 with any SNMP manager, Telnet, SSH.
Multiservice terminal fiber optical multiplexer PoliKom-300U-1GT can be managed by means of PC:
- monitoring of local and remote equipments in real time;
- redesign of local and remote equipments (including loopbacks);
- revision of log in local and remote equipments.
All interfaces of device are compliance with ITU-T G.823, G.747, G.704, G.703, G.651, G.652, G.654.
Available variants of optical interface:
- 1310 nm for 1 fiber mode;
- 1550 nm for 1 fiber mode;
- two-forked transiver 1310/1550 nm for 1 fiber mode work.
