Know more DAC Cables for interconnect solution

 Global optical transceiver&cable market is expected to rise due to rise in demand and update of optical communication technology in our daily life .Today’s network cabling requires lower power ,higher performance with cost-effective network connection .DAC cable is playing a significant role in success of telecommunication. UTOPTICAL would like to talk more about DAC .

Introduction

DAC cables stand for Direct Attach Cables,which are a form of shielded high speed cable with fixed length shielded copper coaxial cables and pluggable transceivers on either end. Normally they can be used to interconnection of switches , routers ,storage devices and servers.

Advantage

1. High performance---It is suitable for short-distance cabling of network solution, which has a scientific layout design to save space with more reasonable length.

2. Low cost--- The price of direct attach copper cables is much lower than that of optical transceivers, there are no active Tx /Rx components, just Capacitors, Resistors, EEPROM, Cable Therefore, the use of high-speed DAC cables can greatly reduce the connection cost of network solution.

3. Low power --- DAC cables with low power consumption. They do not require a power supply, which means they are almost zero,but generally the power consumption of the active optical cable is around 440 mW.

4. energy-saving and environmentally-friendly--- DAC cables save energy and protect the environment due to the internal material of a copper core. Which has a good natural heat dissipation effect .

One of disadvantage is limited distance ,which optical transceiver should be used with cables together , it can not be used separately to network soultion .

Types of DAC 

According to the connector type , DAC cables can be mainly classified as 6 types :

1. 10G SFP+ to SFP+ DAC

Application:SONET/SDH,10G Ethernet,10X Fiber Channel，CPRI/OBSAI

2. 40G QSFP+ to QSFP+ DAC

Application:40G Ethernet, InfiniBand QDR or FDR,OTU3 for OTN

3. 40G QSFP+ to 4xSFP+ DAC

Application: 40G Ethernet, InfiniBand QDR or FDR,OTU3 for OTN

4. 100G QSFP28 to 4SFP28 DAC

Applications
