How to choose the right one 100g dac cable

Industrial Services & Equipment

Everyone is aware that QSFP28 is considered as one of the mainstream forms factors in today’s 100Gbe optics market. Though there are many other products with a QSFP28 form factor like direct attach copper cable, active optical cables as well as transceivers with different interface options such as SR4, LR4, PSM4, CWDM4 and many more. The most basic factor which is used to choose 100g DAC cable is the transmission distance which you may want to reach as well as cable types you plan to use.

For the last many years, the demand for communication bandwidth requirements has been increased to a great extent. The communication service providers whether public or private data centers need high speed as well as bandwidth connections. Due to which demand for 100g DAC cable has increased. This cable aid aggregate data rates of 100Gbps and transmits length up to 3 meters. It is known for its wide operating temperature range from 0℃ to +70℃, while it has low EMI radiation switches, routers and servers. This cable is highly demanded in telecommunication as well as wireless infrastructure.

Most of the switch vendors often choose the smallest form factor transceiver i.e. QSFP28 transceiver. This cable is the small module available and is considered as one of the lowest power consumption cable among those that have the ability to handle 100G traffic. With the construction of 5G networks, the requirement for network speed has been rapidly improved. The high transmission rate & density, as well as low device power consumption of this 100G Ethernet, has attracted more and more attention.

You can easily avail this cable from Fiberland ltd. at a very reasonable price. The QSFP28 is mainly applied to 4×25GE access ports that are mainly utilized to transmit data through four fiber channels. Therefore, the transmission rate in the channel reaches up to 28Gbps which is generally applied in the 100G network. There are mainly two types of 100G QSFP28; one is considered as an optical module and the other one is the application in the optical cable.

The QSFP28 assemblies are convenient as well as lost cost methods of connecting 100G equipment that too with a single assembly instead of three discrete components. Only a few parts are required, but most important, the utilization of cable assemblies can easily remove different problems that are associated with dirty connectors.

The QSFP28-SR4 transceivers assist the connections up to 100 meters over multimode fiber. There are mainly two types of 100G QSFP28 DACs; 100G QSFP28 DAC as well as 100G QSFP28 to 4*SFP28, while both these products have relatively short link length and are known as passive products.  Since this cable has low power as well as low EMI crosstalk which makes it widely used in network transmission.

This cable is great for switch vendors who require handling data that stays within the rack as well as the data center. Therefore, the solution that renders them perfect for both worlds allows the user to get the full advantage of QSFP28 transceivers in the datacom equipment.
