25G SFP28 Transceiver

25G optical transceiver has a transmission rate of 25Gbps, which is mainly used for the interconnection of data center servers and switches. The best input/output (I/O) performance and fiber capacity are 2.5 times than 10G Ethernet, and the port has higher density, which can effectively reduce network deployment costs. 25g transceiver not only makes up for the low rate of 10G optical modules that cannot meet network requirements, but also solves the problems of high prices and excessive power consumption of 100G optical modules.

Gearlink professional transceiver manufacturer also provide a variety of transceivers such as 400g transceiver, 40g qsfp+ transceiver, module sfp 10g, sfp transceiver, direct attach cable and active optical cable. Contact us to get 25g SFP28 price. Buy SFP28 from supplier.

25G SFP28 Transceiver FAQs

Q What Is SFP28 SFP+ Compatibility


SFP28 module refers to the optical module encapsulated as SFP28, the transmission rate is 25G, inserted into the 25G port, and used in 25G Ethernet; SFP+ optical module refers to the optical module encapsulated as SFP+, the transmission rate is 10G, and it is inserted in On 10G ports, it is applied to 10 Gigabit Ethernet. The size and shape of the 10G port and the 25G port are the same. The SFP28 optical module can be inserted into either a 10G port or a 25G port. The actual operating rate when inserted into a 10G port is 10G. When inserted into a 25G port, the actual operating rate is 25G. The SFP+ optical module is fine. A 10G port can also be inserted into a 25G port. The actual working speed of inserting a 10G port is 10G, and the actual working speed of inserting a 25G port is also 10G.

Q What is sfp28?


SFP28 is an enhanced version of SFP+, which has the same size as SFP+, but it can support a single-channel 25Gb/s transmission rate. SFP28 provides an efficient solution for 10G-25G-100G network upgrade, which can meet the continuous growth of the next-generation data center network.

Q SFP28 vs SFP+ Comparison , What Is The Difference?


SFP + and sfp28 transceivers have the same pin arrangement and are compatible with each other. However, SFP + is designed to operate at 10 GB / s, while SFP 28 is designed to operate at 25 GB / s. Compared with SFP + solutions, sfp28 has higher bandwidth, excellent impedance control, and less crosstalk. In addition, compared with SFP + version, the sfp28 transceiver and sfp28 copper cable have greater bandwidth and lower loss.

Q Can I Use SFP+ Transceiver In SFP28 Ports?


The SFP+ transceiver can be used on the SFP28 port, but the actual working rate can only reach 10G.

Q Can the 25G optical transceiver adapt to 10G?


In most cases, optical transceiver s are backward compatible.
