I've seen where the micron is printed on a fiber strand, and that you can identify the connector type, but how do identify the difference between a 50 micron OM4 MMF, a 50 micron OM3 MMF, and a 50 micron OM2 MMF?

I 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 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 a Cisco3800 with IOS Version 12.3(14)T2 and I have an HWIC-1GE-SFP module inserted on it.

Something similar to the following command that I can execute in an Cisco ASR9K:

I am looking for optical transceivers that are compatible with the Cisco 5509 switch. Preferably 1G.

Can we use optical fiber SFP module to connect 2950 switches to core switch?Does Cisco 2950 Switch support optical fiber sfp module?
I have an C4900M with twingig converter and SFP GLC-LX-SMD in. So the SFP supports DOM function. It is running on 12.2(53)SG2.

I'm currently training at a PC store.Me and this other guy are trying to figure out some networking.So far we've file shared 2 PCs with 1 crossover cable.Now we're trying to figure out how to do this with 3 PCs and NO hub, switch, router, etc.I have my theory and he has his.
His theory: One of the computers need an ethernet card so 2 crossover cables can be plugged into it.(The MOBOs only have one port to plug in Cat5s)
My theory: Cut 2 crossover cables in half. And put the three ends together so the wires are touching each other, then tape it. For example green to green to green, orange to orange to orange, etc.Here's an example picture: Now I know my theory would work with audio but me co-trainee isn't so sure if it will work with networking.
