DAC Cable

Best Reliable DAC Cable Provider

DAC (Direct Attach Copper Cable) is irreplaceable in the field of short-distance (less than 7meter) high-speed interconnection due to its four major advantages: ultra-low latency, zero-configuration deployment, cost savings, and high reliability.

 

DAC cable is high speed direct attach copper cable assembly with SFP transceiver’s interfaces at both sides, but without laser or electronic components, therefore it can only transmit electrical signals, not optical signals. However, it is irreplaceable in the field of short-distance high-speed interconnection due to its advantages: ultra-low latency, zero-configuration deployment, cost savings, and high reliability.

DAC cables are mainly used in the following fields:

  • Data centers and cloud computing
  • High performance computing (HPC) and artificial intelligence
  • Military and energy facilities
  • Financial high-frequency trading system
  • Machine vision control
  • In-vehicle server interconnection

1310nm and 1550nm optical module have different loss and dispersion, transmission distance are differ a lot. Please choose as per your need.

  • 1310nm fiber loss at 35dBm/km, used for transmission distance less than 40km, high loss and low dispersion;
  • 1550nm fiber loss at 2dBm/km, can transmit 120km, so >40km, low loss and high dispersion.

There are two networking  in computing center: IB protocol, Ethernet protocol

  • IB protocol use 400G-OSFP-SR4 and 800G-OSFP-SR8 for matching interconnection
  • Ethernet use 400G-QSFP-DD, or QSFP-112 for matching interconnection
  • Inside the machine room: 150M or 300M SR4; short distance module, MPO interface-multimode SR4, LC interface-multimode LX4
  • Between buildings: 2km PSM4, ILR4; MPO interface-single-mode PSM4, LC interface selects LR4, ER4
  • Between cities: 10KM, 40KM, 80KM- LR4, ZR4, ER4; MPO interface-single-mode PSM4, LC interface selects LR4, ER4

400G and 800G ACO cables was shipped in batches starting in 2024 with double assurance:

  1. All laser and DSP chips are Broadcom solutions, the most stable solution among mainstream solutions.
  2. Are all products tested with NVIDIA 9790 network cards or switch, delivered after 100% qualified.

Immersion type from 10G to 400G is mass-produced already, whether single mode or multi mode. Pure immersion type multi-mode is more common, because multi-mode is more widely used in big data integration and computing power data centers. Immersion type liquid-cooled optical modules are more suitable for small clusters with large capacity. 10G, 25G, 40G, 100G, 200G, 400G.

Yingda has 13 years of professional optical module research and development, and has 130 compatibility testing equipment and a complete compatibility database to meet diverse needs. It is compatible with different brands of equipment such as Minos, NVIDIA CX6 and CX7 network cards.
