10G SFP+ DAC and SFP + optical transceiver module

With improvements in cloud computing , cloud storage and network servers . In order to meet this growing demand on the market , there are two main choices on 10G network access connectivity solutions : SFP+ direct attach cable (DAC) and 10G SFP+ optical transceiver modules. Choosing suitable and effective solution is practical needs in different situation.Today UTOPTICAL would like to share more .     

Introduction  

10G SFP+ Direct Attach Copper Cable is a copper interconnect using a passive twin-ax cable assembly that connects directly into an SFP+ connectors on both sides based on SFP+ MSA,which is a smaller electrical component is used to recognize the SFP+ module and cable type to the Ethernet interface.

SFP+ Optical transceiver module does only optical to electrical conversion ,which is hot-pluggable with durable metal enclosure, MSA SFF-8472 compliant . they are interchangeable, compact media connectors and enable a single network device to connect to a wide variety of fiber types and distances.

What are the differences?

The 10G SFP+ DAC cable connects two switches with copper cables, but the SFP + optical transceiver module connects two switches with patchcords.

The 10G SFP+ DAC for short-distance transmission up to 15m, but SFP + optical transceiver module for long distances transmission up to 100km.

Advantages of 10G SFP+ DAC :

10G SFP+ DAC cable is defined for 10G applications over copper cable with SFP + connectors at both ends with lower power consumption and lower latency, which is cost-effective network interconnection solution.

Transmission distance reach 15 meters, which the target application of SFP+ DAC is interconnection of top-of-rack switches and storage devices in a rack.

Advantages of 10G SFP + optical transceiver module :

TOR switch is connected to a network switch, if the distance is more than 15M, selecting 10G SFP + optical transceiver module is better to achieve ,which normally use OM3/OM4 LC patchcord and 10G SFP + optical transceiver module.

 In fact ,10G SFP+ optical module is widely used in long distance transmission.

Summary

This low-cost 10G SFP+ DAC is suitable for interconnection of switches,short-distance connections between switch ports and Ethernet interfaces on servers .10G SFP+ optical transceiver modules are widely used for long distance transmission.so SFP+ DAC cable and 10G SFP+ transceiver module play an important role in 10GbE network systems.
