Product Description

This is an Arista Networks® CAB-O-8S-200G-2M compatible 200GBase-CU OSFP to 8xSFP28 direct attach cable that operates over passive copper with a maximum reach of 2.0m (6.6ft). It has been programmed, uniquely serialized, and data-traffic and application tested to ensure it is 100% compliant and functional. This direct attach cable is TAA (Trade Agreements Act) compliant, and is built to comply with MSA (Multi-Source Agreement) standards. We stand behind the quality of our products and proudly offer a limited lifetime warranty.

AddOn’s direct attach cables are RoHS compliant and lead free.

TAA refers to the Trade Agreements Act (19 U.S.C. & 2501-2581), which is intended to foster fair and open international trade. TAA requires that the U.S. Government may acquire only “U.S. – made or designated country end products.”

Notes: 

  1. The module signal grounds, VeeR and VeeT, shall be isolated from the module case.
  2. This is an open collector/drain output and shall be pulled up with 4.7-10k to Vcc_Host on the host board.
    Pull ups can be connected to multiple power supplies, however the host board design shall ensure that no module has voltage exceeding module VccT/R + 0.5 V.
  3. This is an open collector/drain input and shall be pulled up with 4.7-10k to VccT in the module.
  4. See 2-wire electrical specification.
  5. This shall be pulled up with 4.7-10k to Vcc_Host on the host board.
