Fiber Color Codes

Fiber Color Codes
Inside the cable or inside each tube in a loose tube cable, individual fibers will be color coded for identification. Fibers follow the convention created for telephone wires except fibers are identified individually, not in pairs. For splicing, like color fibers are spliced to ensure continuity of color codes throughout a cable run.

Fiber Optics Acronyms

Acronyms:


SFP: Small Form Factor Pluggable
sfp

XFP: 10 Gigabit Small Form Factor Pluggable
xfp

MU: Miniature Unit
mu
The MU connector, developed by NTT in Japan, is a Small Form Factor (SFF) connector, and can be considered a smaller SC style connector. It is based on a 1.25mm ceramic ferrule and is available in simplex, duplex and higher gangable styles.

LC: Lucent Connector
lc
A small form factor ceramic based connector developed by Lucent.

SC: Subscriber Connector
sc
Originally developed by NTT, the SC connector has a push/pull snap fit. The duplex SC connector uses the same mating profile as the simplex design. A number of SC suppliers actually clip simplex SC connectors together to form the duplex version..

FC: Fiber Connector
fc
The FC connector has a screw-on mating style. Primarily used in the telecom industry, the FC is a robust, highly reliable design.

MTRJ: ‘MT’ ferrule, Register Jack latch
mtrj
This connector is radically different than the other connectors shown, in large part, due to the single ferrule that handles two fibers. This is the first of the Small Form Factor (SFF) connector designs to reach a measure of market acceptance. The MT-RJ is a variation of the reliable MT-ferrule connector series, the first major multi-fiber ferrule design.

ST: Straight Tip
st
Developed by AT&T, the ST connector (for Straight Tip) has been a perennial favorite for its termination simplicity and low cost.

How To Factory Default Cisco Routers

To factory default a Cisco router, you will need to run a couple commands in “rommon”. Send a break a few times to force the router in to rommon. Do this immediately after powering on the router.

rommon>confreg 0x2142
rommon>reset

The router will reload and the config should be wiped. Once you are back in “enable”  mode again, you will need to change the config register back to 0x2102. If you fail to do this, your config changes will not save after a reload or power cycle.

Router(config)#config-register 0x2102
Router(config)#end
Router#write memory
