data rates over single-mode fiber. They are based on the IEEE 802.3 standard and the 100G Lambda MSA specifications. They use a single wavelength of light to transmit and receive data, which reduces the complexity and cost of the optical components. They also have a small form factor and low power consumption, making them suitable for high-density and low-power applications.<\/span><\/p><p><span style=\"font-size: 14pt;\">The main differences between the three types of transceivers are the reach and the interoperability with other modules. The 100G-DR transceiver supports a reach of up to 500 meters over duplex single-mode fiber and can interoperate with 400G DR4 modules in 4x100GbE breakout applications. The 100G-FR transceiver supports a reach of up to 2 kilometers over duplex single-mode fiber and can interoperate with 400G DR4+ modules in 4x100GbE breakout applications. The 100G-LR transceiver supports a reach of up to 10 kilometers over duplex single-mode fiber and can interoperate with 4x100G LR1 modules in 4x100GbE breakout applications.<\/span><\/p><p><span style=\"font-size: 14pt;\">The difference between a legacy 100G QSFP module and a 100G-DR \/ FR module is illustrated below.<\/span><\/p><p><span style=\"font-size: 14pt;\"><img fetchpriority=\"high\" decoding=\"async\" class=\"aligncenter size-full wp-image-5766\" src=\"https:\/\/www.fibermall.com\/blog\/wp-content\/uploads\/2023\/10\/legacy-module-and-dr.png\" alt=\"legacy module and dr\" width=\"767\" height=\"366\" srcset=\"https:\/\/www.fibermall.com\/blog\/wp-content\/uploads\/2023\/10\/legacy-module-and-dr.png 767w, https:\/\/www.fibermall.com\/blog\/wp-content\/uploads\/2023\/10\/legacy-module-and-dr-300x143.png 300w\" sizes=\"(max-width: 767px) 100vw, 767px\" \/><\/span><\/p><p><span style=\"font-size: 14pt;\">The 100G-DR\/FR\/LR modules have a reach of 500m\/2km\/10km over SMF, and are designed to interoperate with 400G-DR4\/XDR4\/PLR4 transceivers using a <a class=\"wpil_keyword_link\" href=\"https:\/\/www.fibermall.com\/blog\/breakout-cable.htm\"   title=\"breakout cable\" data-wpil-keyword-link=\"linked\" target=\"_blank\">breakout cable<\/a>.
