Product Overview


Introduction and application of 25G SFP28 DAC

 

The 25G SFP28 DAC (Direct Attach Cable) consists of a copper cable and a transceiver module device at both ends, using silver-plated conductors and foam-insulated cores, with excellent attenuation performance and low latency performance, so that the signal transmission is accurate, but also can increase the transmission speed. It is a short-distance connection solution instead of an optical module.


                                                   


The connector of the SFP28 DAC is similar to that of the optical module, but it has no expensive laser inside, so the price is much cheaper than that of the same type of optical module. Therefore, the 25G SFP28 DAC passive copper cable is a cost-effective choice in short-range high-speed transmission schemes. Next, Fiber Mall will introduce the SFP28 DAC and its applications.

 

1) Introduction of 25G SFP28 DAC

 

1. Length range of 25G SFP28 DAC passive copper cable

 

Fiber Mall's 25G SFP28 DAC passive copper cables are available in custom lengths (1-5M) to meet customer needs.

 

2. 25G SFP28 DAC compatible switch brands

 

Fiber Mall's 25G DAC cable is compatible with Huawei, Cisco, HP, IBM, H3C, Juniper, Mikrotik and other switch brands.

 

3. Application scenarios for 25G SFP28 DAC

 

-25G Ethernet data center server room

-Storage area network

-Supercomputing center system

-Switches/routers/HBAs, etc.

                                        Fiber Mall 25G SFP28 DAC


The 25G SFP28 DAC passive copper cable is widely used in data centers because it can improve data center network performance while effectively reducing the number of top-of-rack switches deployed in data centers. In addition, when 10G Optical modules can not meet the rate requirements of most data centers, the price and power consumption of 40G and 100G products are too high, and the 25G SFP28 DAC can just meet the requirements of low power consumption and low cost of data centers.

 

4. Types of 25G SFP28 DAC:

 

·25G SFP28 to SFP28 DAC

It is a very cost-effective solution for short-distance link transmission, which can establish 25G link through the SFP28 port of the switch, complying with IEEE P802.3by and SFF-8402 SFP28 standards, and is widely used in data center or supercomputing center system scenarios.

 

·100G QSFP28 to 4 x SFP28 DAC

 These SFP28 DACs are suitable for stacking and clustering between short-range big data devices, with 100G QSFP28 interfaces on one end and four 25G SFP28 interfaces on the other end, providing customers with 100G data transmission, which is compliant with IEEE 802.3BA standard, SFF-8665/SFF-8679, IEEE 802.3bj and InfinibandEDR standards.

 

2) 25G SFP28 DAC vs AOC

 

The 25G SFP28 DAC can support up to 25Gbps transmission rate, which is higher than the data transmission rate supported by traditional copper cable; The SFP28 DAC is mainly used in switches/routers/HbAS, servers and data storage devices, 40GBs/100Gbs Ethernet and fibre channel.


                                      Fiber Mall SFP28 DAC vs AOC


The 25G SFP28 AOC is one-half the size and one-quarter the weight of the SFP28 DAC, so the 25G AOC is much lighter than the 25G DAC. The SFP28 AOC is suitable for 25G and 10G Ethernet, high-capacity IO with SFP+ interface, data center and inter-rack connectivity.

 

Fiber Mall, as a professional optical module manufacturer, is a brand to be preferred and trusted. We offer reliable quality 25G SFP28 DACs and can provide customized services.
