DAC (Direct Attach Cable)

We provides a high-speed and  cost-efficient solution for data center applications. we are offering an alternative to optical transceivers and Active Optical Cables (AOCs) for transmission distances up to 7 meters. Each DAC comes with an EEPROM that allows the host system to access product information for smooth integration. Engineered with superior s-parameter and impedance control, our product delivers energy-efficient, high-bandwidth connectivity with minimal power usage and cost. It ensures optimal installation, performance, and durability whihc is supports data rates of up to 400 Gbps. We offer a customise lengths and ensure compliance with global standards.

FAQs of Direct Attach Cable

CWDM4 MSA is a general specification for low-cost 100g optical interface, 2km in data center application.

CWDM4 MSA alliance was jointly launched by Avago, Finisar, JDSU and Oclaro on March 31, 2014. Four 25gbps signals are used and multiplexed to two single-mode optical fibers by CWDM. IEEE 802.3bj kr4 RS FEC technology is adopted.

CWDM MSA said the release of the standard has collected feedback from more than 40 companies, including system OEMs, optical module manufacturers, chip manufacturers, fiber optic cable manufacturers, etc. At present, members of cwdm4 MSA alliance include:

Avago Technologies

MZ, Mach Zehnder, Mach Zehnder modulator. The modulator divides the input light into two equal signals and enters the two optical branches of the modulator respectively. The materials used in the two optical branches are electro-optical materials, and their refractive index varies with the external applied electric signal. Because the change of the refractive index of the optical branch will lead to the change of the signal phase, when the output ends of the two branch signal modulators are combined together again, the synthesized optical signal will be an interference signal with varying intensity, which is equivalent to converting the change of electric signal into the variation of optical signal and realizing the modulation of light intensity.
