The coaxial"or any other metal cable" was using for transmission signals(before fiber optic) the coaxial need repeater every 2 or 3 Kilo meter,because the signal will be attenuation when pass through the cable,when we transmission electricity to far places ,we use transformer to rising the voltage to 10000 or 100000 volt

View 7 Replies View RelatedI have a ONT with a built in router but I need to install a separate router onto our network by connecting the router to the ONT. I need the extra router so that I could use some 3rd party hardware which can only be configured in D-link and Tp-link brand routers. I do not want to change the ONT system to the standard modem router system because the ONT also supports a system of internet phones. I'm curious if this is possible at all because a repair tech. told me that you could use the router as a transformer but so far it is not working. I'm really unfaimilar with the ONT configuration so I don't know if this plan can actually work . So far the router can not recieve a WAN connection and therefore can not obtain a Ip address.

I whish to connect the two switches shown below.The distance between them is 50m (~54 yards), one floor apart, and I would like to link them with the cheapest optical solution possible.I have been given a solution with 19inch patch panel, splitter, pigtail cords, patch cords, SC connectors, i.e., the lot.Not being an expert in networking, I feel that is an overkill solution.

I was positively surprised to find the optical transmit/receive values using the show fiber-ports optical-transceiver detailed command on a SG300-10.
Now I'm wondering if there is also a SNMP-MIB to query these values? I've already tried the CISCO-ENTITY-SENSOR-MIB used by the larger devices running Cisco IOS, but this didn't work.
I have two SG300-20 Switches and buy two MGBLX1 Modules for the Switches.
I plugedin the Modules but the Modules didn`t work and in the WebConsole i can´t see the Modules.
Is there any configuration to enable the SFP Modules? or is it a problem from my Switches
We're installing ASR1000 series (ASR1001 and ASR1006) routers on a new WAN and have a requirement to enrypt the traffic between the EIGRP neighbors. Each ASR will be connected to the MOE with a gig interface and we will be using L3 on the interfaces with EIGRP as the routing protocol. We have advipservices-k9 IOS-XE
The ASR1006 is our datacenter WAN router and all remote sites have the ASR1001s. The ASR1006 WAN interface will be configured with L3 subinterfaces, one to each remote location, using a /30 mask.
What is the best method to encrypt the traffic between the ASR1006 WAN interface and the remote ASR1001 WAN interface?
I have 2 computers running Slackware 13.37 and each has a T10/100 ethernet card/port. I want to create an ethernet network between them to pass text and possibly backup. I have given them 192.168.2.1 and 192.168.2.2. I want to be able to cut the connection at will. If I recall correctly there are 2 types of LANs one is NFS and NIS. Which would be the best for this purpose and where can I find a stepwise approach to setting it up?

2. The fact is that I have a cheap, simple chinese WiFi-ADSL-modem ZTE, which has 3 modes - low / medium / high for WI-FI signal. So, the signal is transmitted by ZTE at LOW-level is equivalent to signal, which now sends my WAG320N. When I turn ZTE on high-level, then the range of wi-fi signal increases much, comparing with the range given by WAG320N. So, where can I turn on high-mode in my WAG320N?
