Passive DACs are ideal for short distances (typically under 7 meters) like this 50cm model, while active cables support longer reaches. For Arista deployments within rack environments, passive DACs deliver superior value without performance compromise.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003ch3\u003eIs this 100GBASE-CR4 QSFP28 cable compatible with all Arista switches?\u003c\/h3\u003e\n\u003cp\u003eThis cable is designed for Arista platforms supporting 100GBASE-CR4 QSFP28 interfaces. Compatibility depends on your specific Arista switch model and port configuration. We recommend verifying your equipment specifications before purchase. ENET Solutions ensures full compliance with Arista standards for seamless integration.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003ch3\u003eWhat are the typical use cases for a 50cm passive DAC cable?\u003c\/h3\u003e\n\u003cp\u003eThe 50cm length is perfect for short-reach connections including switch-to-server links, top-of-rack (ToR) to aggregation switch connections, and equipment within the same cabinet or adjacent racks. This distance eliminates the need for longer cable runs while maintaining 100 Gigabit performance in dense data center environments.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003ch3\u003eHow does the passive DAC cable reduce total cost of ownership?\u003c\/h3\u003e\n\u003cp\u003eBy eliminating active transceiver modules and their associated power requirements, passive DAC cables significantly reduce capital and operational expenses. The 100GBASE-CR4 QSFP28 passive design requires no power supply, generates minimal heat, and requires no firmware management—lowering your data center's overall infrastructure costs.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e\n\u003c\/div\u003e","brand":"ENET SOLUTIONS","offers":[{"title":"Default Title","offer_id":41647360016459,"sku":"CAB-Q-Q-100G-50CM-ENC","price":247.0,"currency_code":"CAD","in_stock":true}],"url":"https:\/\/www.tecisoft.ca\/products\/enet-100gbase-cr4-qsfp28-passive-dac-50cm-arista","provider":"TeciSoft","version":"1.0","type":"link"}
