What and where to use 25G SFP28 Optical Transceivers and Cables?

SFP28 stands for Small Form-Factor Pluggable 28. It is the third generation of the SFP interconnect systems designed for 25G performance per the IEEE 802.3by specification (25GBASE-CR). It has the same common form factor as the SFP+, and supports 25Gbps electrical interfaces per channel, making it a cost-effective way to connect within racks and across adjascent racks. It has the characteristics of low power consumption, small volume and high speed, which is beneficial to increase capacity of data center, improve port density and reduce power consumption.

What are Small Form-Factor Pluggable Transceivers and their Types?

A SFP (Small Form-Factor Pluggable) transceiver is a compact, hot-swappable device that can be used for both transmit and receive data and also plugs into a physical port of a network device.  It is used in the communication network and has a transmitting side and receiving side. The SFP transceiver has a laser which communicates with the receiving side of the other optic on the other side. SFP transceivers are designed to support several communication standards including SONET, Gigabit Ethernet and Fibre Channel, and their interfaces on a networking device such as a router provides a modular device that can be freely adjusted to fiber optic and copper networking specifications.

Understand 10G SFP+ Transceiver From the Perspective of Connecting Cable Types

Different SFP+ transceivers can provide a wide variety of connectivity options. There are several approaches for us to understand 10G SFP+ transceivers family. For example, with the compliance to different 10G Ethernet standard, we can classify transceivers as 10GBase-SR, 10GBase-LR, 10GBase-ER, 10GBase-ZR etc. Or viewing from the port type, we can see the difference between the SFP+ transceiver configured with duplex LC connector or a RJ-45 connector. But there is another approach we can understand and distinguish SFP+ transceivers. And That is waht I am going to talk about: the Connecting Cable Types.
