bacaartikeldisiniaja -- To solve the problem, fiber optic technicians must select the most appropriate patch panel for their particular situation. This engineer should be aware that not all patch panels are created equal when it comes to ease of installation, proper termination, and long-term maintenance. Fiberglass is tough and requires special handling. for example:
Damage to the horizontal copper cable affects the user. A failure of the backbone fiber can result in a large number of users. For this reason, it is important to use completely sealed interconnect hardware for fibers. The technician now has to choose whether to use wall-mounted or rack-mounted hardware.
The required fiber density can influence a technician's choice of wall-mounted or rack-mounted connections. Many technicians choose fiber optic patch cords. Leave it to the technicians to decide what is best. The wall mount enclosure supports up to 24 fibers, but with a small form factor and high density connectors you can scale up to 144 fibers.
Wall-mounted enclosures also have the advantage of a smaller footprint. Rack-mount fiber optic enclosures can be used for high fabric counts or near telecom equipment where rack-mount fiber optic enclosures are preferred. The 1U chassis can accommodate up to 24 fiber optic cables when using ST or SC connectors, or up to 48 fibers when using small form factor connectors. For added protection, 2U to 4U enclosures can be used to handle up to 144 fiber links. The 12-fiber MPO connector can reduce installation time and increase connectivity hardware concentration.
Factory-assembled and tested cassettes reliably split fiber optic cables from MPO connectors to his ST, SC, or MT-RJ connectors. MPO cassettes can double the density possible in a rackmount enclosure (up to 72 fibers in a 1U enclosure and up to 288 fibers in a 4U enclosure). These fibers are ideal for high density applications such as data centers and storage area networks.
Accessibility is a concern for long term maintenance when choosing a rack-mount enclosure. The 1U enclosures may have a an access panel to reach the rear optic fibers, while larger enclosures may have a removable rear cover with adequate room inside to make changes or perform repairs. Strain relief and loop management for incoming cables must be provided, nonetheless management devices should be small enough as to not interfere with access to the optic fibers.
Cable management for patch cords should be provided on the front of the enclosure with clear front covers and labeling arranged to ease moves, adds and changes and by ensuring that port identification is not obscured by patch cords.
Since copper patch panels need to be strong enough not to flex too much as the cables are punched down. The rolled edges on the panel sheet metal stock help to make the panels rigid. Copper patch panels should provide 24 ports in a 1U height or 48 ports in a 2U height.
It's very important to make sure that the modular jacks and circuit traces on the panels are protected from debris that can short out circuits. All cable management systems must be easy to use and maintain to avoid any potential problems.
