O padr\u00e3o 100G normalmente emprega modula\u00e7\u00e3o NRZ (Non-Return-to-Zero), embora as infraestruturas mais recentes prontas para 400G possam envolver PAM4 (Modula\u00e7\u00e3o de Amplitude de Pulso).<\/p>\n<p style=\"box-sizing: border-box; line-height: inherit; margin-top: 22px; margin-bottom: 22px; color: #252933; font-family: -apple-system, 'system-ui', 'Segoe UI', Helvetica, Arial, sans-serif, 'Apple Color Emoji', 'Segoe UI Emoji'; font-size: 16px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; white-space: normal; background-color: #ffffff; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;\">Para m\u00f3dulos CWDM4 e LR4, o dispositivo usa quatro comprimentos de onda distintos centrados em 1310nm.

Por que o consumo de energia \u00e9 importante para transceptores 100G QSFP28?<\/strong><\/p>\n<p style=\"box-sizing: border-box; line-height: inherit; margin-top: 22px; margin-bottom: 22px; color: #252933; font-family: -apple-system, 'system-ui', 'Segoe UI', Helvetica, Arial, sans-serif, 'Apple Color Emoji', 'Segoe UI Emoji'; font-size: 16px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; white-space: normal; background-color: #ffffff; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;\">O alto consumo de energia leva ao aumento da gera\u00e7\u00e3o de calor dentro do chassi do switch. Em implanta\u00e7\u00f5es de alta densidade, isso pode exceder a capacidade de resfriamento do data center, causando estrangulamento t\u00e9rmico ou falha de hardware. M\u00f3dulos com efici\u00eancia energ\u00e9tica ajudam a reduzir o custo total de propriedade (TCO) e a melhorar a confiabilidade do sistema.<\/p>\n<p style=\"box-sizing: border-box; line-height: inherit; margin-top: 22px; margin-bottom: 22px; color: #252933; font-family: -apple-system, 'system-ui', 'Segoe UI', Helvetica, Arial, sans-serif, 'Apple Color Emoji', 'Segoe UI Emoji'; font-size: 16px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; white-space: normal; background-color: #ffffff; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;\"><strong style=\"box-sizing: border-box; font-weight: bolder;\">4. MPO-12 ou MPO-24 s\u00e3o melhores para conex\u00f5es 100G SR4?<\/strong><\/p>\n<p style=\"box-sizing: border-box; line-height: inherit; margin-top: 22px; margin-bottom: 22px; color: #252933; font-family: -apple-system, 'system-ui', 'Segoe UI', Helvetica, Arial, sans-serif, 'Apple Color Emoji', 'Segoe UI Emoji'; font-size: 16px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; white-space: normal; background-color: #ffffff; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;\">Para 100G QSFP28 SR4, o conector MPO-12 \u00e9 o padr\u00e3o da ind\u00fastria. Ele usa 8 das 12 fibras para criar quatro pistas de 25 Gbps. Embora o MPO-24 possa ser usado com adaptadores, ele adiciona complexidade desnecess\u00e1ria e potencial perda de inser\u00e7\u00e3o ao link de fibra sem fornecer benef\u00edcios adicionais de desempenho.<\/p>\n<p style=\"box-sizing: border-box; line-height: inherit; margin-top: 22px; margin-bottom: 22px; color: #252933; font-family: -apple-system, 'system-ui', 'Segoe UI', Helvetica, Arial, sans-serif, 'Apple Color Emoji', 'Segoe UI Emoji'; font-size: 16px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; white-space: normal; background-color: #ffffff; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;\"><strong style=\"box-sizing: border-box; font-weight: bolder;\">5. Um m\u00f3dulo 100G LR4 requer FEC (Forward Error Correction)?<\/strong><\/p>\n<p style=\"box-sizing: border-box; line-height: inherit; margin-top: 22px; margin-bottom: 22px; color: #252933; font-family: -apple-system, 'system-ui', 'Segoe UI', Helvetica, Arial, sans-serif, 'Apple Color Emoji', 'Segoe UI Emoji'; font-size: 16px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; white-space: normal; background-color: #ffffff; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;\">Sim, a maioria dos m\u00f3dulos 100G QSFP28, incluindo o LR4, contam com Host-FEC (RS-FEC) conforme definido em IEEE 802.3bj. O FEC ajuda a corrigir erros de bits causados \u200b\u200bpela degrada\u00e7\u00e3o do sinal em longas dist\u00e2ncias. Certifique-se de que a porta do seu switch seja compat\u00edvel e tenha o FEC habilitado para atingir a dist\u00e2ncia total de transmiss\u00e3o de 10 km.<\/p>","protected":false},"excerpt":{"rendered":"<p>This professional guide provides an in-depth analysis of 100G QSFP28 modules to assist network engineers in procurement.
