10Gtek's SFP+ Passive DAC cables products typically have limited or no backward

It should be noted that while most servers are open, compatibility issues can occur with a few CNA server cards (noted below). Additionally some FCoE ports require active copper cables. Panduit SFP+ 10 Gb/s Active and Passive Cable Assemblies are compatible with any switch or server that includes MSA compliant SFP+ ports, unless that product requires active cable assemblies or...

(SFP) transceivers operate at SFP 1.25Gb/s and are compatible

In 1000BASE-T and 100BASE-TX modes, the transmit data stream is scrambled to reduce radiated emissions and to ensure that there is no correlation between symbols in the data stream.Supporting 10/100/1000 Mbps data-rate in excess of 100 meters (325 feet) reach over UTP Category 5/5e cables, the robust SFP-1GBT-05 transceiver module is ideally suited for implementing small ...
