Wiitek [Green Colored] 2m 10G SFP+ DAC Twinax Cable, 10Gbase-CU SFP+ Copper Cable, Compatible for Cisco SFP-H10GB-CU2M, Ubiquiti, Juniper, Mellanox, Mikrotik, Netgear, Supermicro, Open Source Switches

Great quality and works great. Nice colors. Wish they had these in Orange rather than red but that's it. Pull tab is better quality being flat, compared to the cheap O-ring style eject tabs on H!-Fiber's DACs.

First of all, two of the the three email contacts on the Wiitek website failed to send due to the fact that they apparently do not exist. The only one that didn't bounce was "Tony's" address. Secondly, these are definitely not "100% Cisco Compatible" SFP cables. We attempted to use two of the red 1.5M cables to link a pair of brand new Cisco Catalyst 9500 switches to a stack of 3850's and both of the ports they were plugged into started kicking out the following identical messages in the log:Feb 1 20:58:15.179: %TRANSCEIVER-3-RPC_FAILED: Chassis 2 R0/0: iomd: Application error rc = 6: -Traceback= 1#7c8fa7b5e97a2ed2138816e715b5d591 errmsg:7FDB5CAE4000+D20 iomd_spa_infra:7FDB68F15000+5469D iomd_spa_infra:7FDB68F15000+4A6B0 iomd_spa_infra:7FDB68F15000+4B45E spa_ipc_shim:7FDB4B41F000+4D0DD if_combined_ngwc:7FDB436DD000+4BAE7 if_combined_ngwc:7FDB436DD000+4B8C8 :557C9521C000+6569B evutil:7FDB5925E000+78E5 evutil:7FDB5925E000+770F evlib:7FDB5D67E000+8D8E evlib:7FDB5D67E000+9A9C :557C9521C000+645C1 :557C9521C000+6452D :557C9521C000+64363 :Feb 1 20:58:25.612: %SFF8472-3-THRESHOLD_VIOLATION: Twe2/0/47: Rx power high alarm; Operating value: -33.0 dBm, Threshold value: -40.0 dBm.Feb 1 20:58:25.612: %SFF8472-3-THRESHOLD_VIOLATION: Twe2/0/47: Tx power high alarm; Operating value: -5.6 dBm, Threshold value: -40.0 dBm.Feb 1 20:58:25.612: %SFF8472-3-THRESHOLD_VIOLATION: Twe2/0/47: Voltage high alarm; Operating value: 3.36 V, Threshold value: 0.00 V.Feb 1 20:58:25.612: %SFF8472-3-THRESHOLD_VIOLATION: Twe2/0/47: Temperature high alarm; Operating value: 19.9 C, Threshold value: 0.0 C.Buyer beware, thoroughly validate these cables before putting them into production.

What else can I Say. My switch says it failed... flashing red light after 2 hours of operation.

Short 10g cable that can be used to connect two switches. Works great and reasonably priced.
