Analysis of advantages and disadvantages of high-speed cable DAC and active optical cable AOC

High-speed cables and active optical cables are now widely used. Their wire materials are different, but their functions are the same. Then some customers asked, since the functions are the same, how to choose? What are their advantages and disadvantages? According to customer requirements, let’s talk about the advantages and disadvantages of high-speed cables and active optical cables!

According to the material of the cable, it can be divided into:

High-speed cables, including active high-speed cables and passive high-speed cables (DAC)

Direct Attach Cables

Advantage:

◆ Higher data transmission rate: The current high-speed cables can support data transmission rates of 4Gbps to 10Gbps, which is higher than that supported by traditional copper cables.

◆ Strong interchangeability: With the development of copper technology, high-speed cables and optical transceivers are interchangeable and hot-swappable.

◆ Low cost: Copper cables are cheaper than optical fibers, and using high-speed cables will reduce wiring costs.

◆ Good heat dissipation: The high-speed cable is made of copper core, which has good heat dissipation effect.

Disadvantages:

◆ The transmission distance is short, heavy, bulky and difficult to manage.

◆ Easily affected by electromagnetic interference, such as problems such as bad response and degradation.

Active Optical Cable (AOC) : We often say that the active optical cable AOC is also called the optical cable with chip. The optical path part of its main components includes a lens and a FA for converting the optical path angle;
The circuit part includes PCB board, substrate, VCSEL chip, VCSEL driver chip, PD chip, TIA chip and so on. There are two key processes in the AOC manufacturing process: chip mounting process and fiber coupling process, which are also the biggest technical difficulties. The chip mounting process used by AOC is the cutting-edge Flip-Chip process (also known as flip-chip mounting method), which is a chip interconnection technology and an ideal chip bonding technology.

Active Optical Cable (AOC)

Advantage:

◆ Greater bandwidth: no equipment upgrade required, with a throughput of up to 40Gbps.

◆ Lightweight: much lighter than high-speed cables.

◆ Low electromagnetic interference: Since the optical fiber is a dielectric, it is not easily affected by electromagnetic interference.

Disadvantages:

Compared with high-speed cables, active optical cables are more expensive.

Active Optical Cable (AOC) Cabling Solution

With the advent of 5G, the rapid application of the Internet and smart terminals has caused an explosion in global data volume, which has greatly promoted the development of high-performance supercomputing centers (HPC) and data center markets with high-speed routers, supercomputing and storage as the core. UPONCOMM’s active optical cable products are one of the main interconnection methods between these core devices. The advantages of AOC products are high speed, high density, low cost and low power consumption. We are a complete semi-automated AOC product line, the main products include 10G SFP + AOC, 25G SFP28 + AOC, 40G QSFP + AOC, 100G QSFP28 + AOC, 40G QSFP + 4SFP + AOC, 100G QSFP28 + 4SFP28 + AOC, 40G QSFP + 8LC AOC and more…

Significant advantages and applications of high-speed optical interconnect technology

The demand for higher bandwidth and lower power consumption of data center / cloud computing systems is more and more urgent. AOC active optical cable is one of the best solutions to meet this demand. AOC active optical cables have many significant advantages over interconnected copper cables. For example, the transmission power on the system link is lower, the weight is only a quarter of the direct-connected copper cable, and the volume is slightly half that of the copper cable. The cabling system has better air flow and heat dissipation. The bending radius of the optical cable is smaller than that of the copper cable, and the transmission distance is longer (up to 100 ~ 300 meters), and the bit error rate of the product transmission performance is also better. BER can reach 10 ^ -15. Compared with the optical transceiver module, the AOC active optical cable has a non-exposed optical interface, does not have the problem of cleaning and pollution of the optical interface, the system stability and reliability are greatly improved, and the maintenance cost of the equipment room is reduced.

In the data center computer room, devices (servers, switches, HBAs, etc.) that provide various high-speed optical communication ports need to be connected together by cables for common operation. So how to solve the interconnection of any two kinds of equipment? For example, 10G SFP + and 40G QSFP + equipment. Active optical cable QSFP + to 4 SFP + AOC optical interconnection products have become a better solution to realize and solve the interconnection of QSFP + and SFP + equipment.

Customizable length: In order to meet the needs of different customers, UPONCOMM introduces AOC customized services for active optical cables. More scientific layout design and more reasonable cable lengths help you save wiring space and save wiring costs.
