Xmethod Network

Ethernet switch is an interesting field which includes difference media types, management/unmanaged, PoE/non-PoE and various accessories. 

Xmethod Network is focusing in:

1.  L2+ pure optical/multi-port 10G SFP+ Ethernet switch with various unique.

2. Power Over Ethernet PoE switch.

3. Media converter and Optical bypass units.

4. Network accessories, such like BiDi transeciver, 10GBased-T transeciver, DAC cables.

Xmethod Network is capable and willing to provide the best product with the best service to those in need in the market to help developing better network.

The term DAC cables, DAC stands for "Direct Attach Cables", are a form of shielded high speed cable with SFP/SFP+ connectors on both ends. DAC cables can be used to connect SFP/SFP+ ports on Ethernet switches to routers and/or servers which also has SFP/SFP+ ports. DAC Cables are becoming increasingly popular in the network industry, mainly because the price difference is large when compared with regular optics transecivers and fiber cables. In addition, due to RJ-45 10G is not widely adopted, and most high density 10G switches are delivered with 48x SFP+ ports in 1 Rack Unit.

There are versions of cables on the market. Because high speed cables are sensitive to electromagnetic fields, the shielding is an important quality factor for the cables. This is written on the cables in the form of AWG ratings like 28AWG and 30AWG: The longer the distance, the higher the AWG rating should be.

 The most basic version of DAC cable is the 'Passive Assembly' where the data cables are directly connected to the Transmitting and Receiving signal. It depends on the master chip on host board whether the signals are able to reach up to 5 meters.

Xmethod Network provides different lengths of DAC cable to the market, as well as the length of the DAC that can be supported for Xmethod Network Ethernet switches is mentioned in user manual clearly.
