Compatible GLC-FE-100BX-U are an equivalent solution for overpriced original GLC-FE-100BX-U from Cisco, which primarily serve as a margin product for the manufacturer, filling the pockets of the company at your expense. As today's standard for the transmission of optical signals in a fiber-optic network, compatible Cisco GLC-FE-100BX-U provide a way to build high-availability connections in high-speed networks in hardware from different manufacturers without having to compromise the arbitrary Cisco price policy of the large world conglomerates. A Cisco compatible GLC-FE-100BX-U offers the same range of functions as an original GLC-FE-100BX-U and differs only in the product label. The technical set-up of Cisco compatible GLC-FE-100BX-U and of original GLC-FE-100BX-U is the same as defined by MSA standards. Only the quality of the installed components can vary. Cisco compatible GLC-FE-100BX-U from the brand BlueOptics use only high-quality brand lasers (such as Avago or Lumentum) and high-quality ICs (such as Maxim Integrated or Netlogic) and therefore have the same quality or even a better quality as the original GLC-FE-100BX-U from Cisco.
