A brief introduction of 100G QSFP28 DAC Cable

With the construction of 5G networks, people's requirements for network speed have been rapidly improved. 100G Ethernet has attracted more and more attention due to its high transmission rate and density, and lower device power consumption. Among 100G Ethernet products, 100G optical modules, 100G AOC and 100G DAC occupy the main part. Fiberland Ltd. will give a detailed introduction to the 100 QSFP28 DAC Cable

 

First we need to understand what is 100G QSFP28

QSFP28, applied to 4x25GE access ports, mainly transmits data through 4 fiber channels.

The transmission rate in the channel can reach up to 28Gbps, which is mainly applied in the 100G network. There are two types of 100G QSFP28, one is the optical module, and the other is the application in the optical cable.

 

* Optical modules mainly include: 100G QSFP28 PSM4 optical module, 100G QSFP28 CWDM4 optical module, 100G QSFP28 SR4 optical module, 100G QSFP28 LR4 optical module, 100G CF/CF2/CF4 optical module, etc.

* Cables or cables are: 100G QSFP28 AOC and 100G QSFP28 DAC.

 

Second, we will focus on 100G QSFP28 DAC CABLE

In Fiberland Ltd., there are two types of 100G QSFP28 DACs, 100G QSFP28 DAC and 100G QSFP28 to 4*SFP28. Both products have a relatively short link length and are passive products.

Their ideal range of use is 5m and can be transmitted up to 7 meters. They are primarily used for connections between servers and switches, storage and switches, and switches and switches.

Their operating temperature: 0 ~ 70 ° C; and has low power and low EMI crosstalk, the advantages of optimized design for signal integrity.

 

This also makes the 100G QSFP28 DAC cable more and more widely used in network transmission.
