  • How to remove the XFP optical module

    How to remove the XFP optical module

    Next, the first step is to disconnect the network fiber cable from the XFP connector with affixing a dust cover over the optical connector. Gently pull the module latch or release ring, depending on the module design. Remove the module in a straight motion. This chapter describes how to install and remove small form-factor pluggables (SFP modules or XFP modules) on the Cisco ASR 1000 Series Fixed Ethernet Line Card. This chapter contains the following sections: •Removing and Installing SFP Modules, page 4-35 •Removing and Installing XFP Modules, page. You can remove an XFP module from your Extreme Networks switch or I/O module without powering off the system. Rotate the handle (bail latch) on the XFP module. To remove an SFP or XFP transceiver (see Figure 1): Have ready a replacement transceiver or a transceiver slot plug, an antistatic mat, and a rubber safety cap for the transceiver. Small Form-factor Pluggable modules (SFP module) are the workhorses of modern network connectivity, enabling flexible fiber optic or copper links between switches, routers, firewalls, and servers.

  • How to measure the distance to a fiber optic cable break

    How to measure the distance to a fiber optic cable break

    An Optical Time Domain Reflectometer (OTDR) sends light pulses through a fibre optic cable. These pulses travel down the fibre and reflect when they encounter inconsistencies, like breaks, splices, or bends. Here's a guide to identifying the location of a break in a fiber optic cable, including the tools and techniques needed for accurate diagnosis. For some. These length testers use a “round-robin” method of measuring fiber length. The round trip time that the light takes to travel through both fibers is converted to length in kilometers, then divided by two. Measure up to 4,921 feet (1,500 metres) of fiber in seconds Quick set-up. No lengthy set-up necessary Find problems quickly. Six-second test time—no more blind troubleshooting that can waste hours Visible in dark areas.
