![]() ![]() The most common optical wavelengths for this transceiver are 1310/1490 nm, 1490/1550 nm, and 1310/1550 nm. The common types of BiDi transceivers used in today's networks are 1G/10G BiDi SFPs. In point A the RX frequency is listening on 1490nm. In point B there is a transceiver that receives RX on 1310 nm and transmits back to point A on 1490nm on the same fiber. ![]() For example, from point A we have installed a transceiver that transmits TX on 1310nm towards point B on a single fiber. However, for BiDis, we should use two modules: one for the upstream ("U") direction and another for the downstream ("D")-each part transmits at an opposite wavelength. Like traditional transceivers, BiDi transceivers should be deployed in pairs. Bi-Directional technology means a communication mode that processes data in both directions (send and receive) over optical fiber, which allows transceiver modules to transmit and receive data to/from the interconnected network devices (like network switches or routers) via a single optical fiber.īiDi modules are equipped with WDM couplers/diplexers to combine or separate data transmitted over a single fiber using the different wavelengths of the light. There are also LC simplex and MTP/MPO interfaces.ĭifferent combinations: The copper SFP module is usually used with CAT5, CAT6,CAT6A or CAT7 types of network cables, and the fiber optic SFP modules are generally connected between the fiber patch cords.ĭifferent parameters: the copper SFP module has no wavelength, but the fiber optical SFP module does.ĭifferent components: The components of the copper module and the fiber optical SFP module are different, especially the copper SFP module does not have the core component which is the laser.Bi-Directional (BiDi) Transceiver is a compact optical transceiver module that uses WDM (wavelength division multiplexing) technology and is compliant with the SFP multi-source agreement (MSA). What is the difference between an copper SFP module and fiber optical SFP module?ĭifferent interfaces: The interface of the copper SFP module is RJ45, and the interface of the fiber optical SFP module is mainly LC duplex. It can be used in the SFP+ port of a switch or network card to connect to a network device with an RJ45 interface. It is mainly used in 10 Gigabit Ethernet, and the 10G SFP+ copper SFP module is the first 10G optical module to be transmitted over a network cable. The 10G copper SFP+ module is designed for high-speed communication links. This copper port module is more innovative in terms of speed and can meet different application needs. ![]() The 10/100/1000BASE copper port SFP module can be used for high-speed Ethernet and Gigabit Ethernet, unlike other copper modules. The 1000Base copper SFP module can be used for gigabit ethernet,this speed rate is fixed so few customer will choose this. The 100Base copper SFP module can be used when the device network port is insufficient. The following are the descriptions of the copper SFP modules of the three different application types. In addition, the copper SFP module can not only make up for the shortage of SFP+ high-speed cable transmission distance, but also can directly use the existing copper cabling system to achieve data transmission at a rate of 10G, while the use of SFP+ optical modules requires cable routing,which will increase the cost of network deployment. The copper SFP module complies with SFP MSA and IEEE Std 802.3-2002 standards, featuring low power consumption, high performance, and compact design. In addition, since the transmission distance of the copper module is 10-30m or 80-100m, the copper SFP module is mainly used for short-distance data transmission.įeatures and advantages of the copper SFP module The copper SFP module is also called the fiber port convert copper port module. It is a module that supports hot plugging and is in the form of SFP. And The connector type is RJ45. In this article, Sopto will tell you about the knowledge and solutions of the copper SFP module. ![]() The answer is no, because the performance of copper module is also quite good,which has a unique advantage. As we know,fiber optical SFP modules is widely used in the data center solutions,but the copper SFP modules is not.Is the performance of the fiber optical SFP modules higher than copper SFP modules? ![]()
