SFP+ optical modules are next-generation hot-pluggable, small form factor, serial-to-serial, multi-rate optical transceivers typically used in 8.5GbE to 11GbE datacom and storage area networks (SANs). It is a variant of traditional SFP optical transceiver with enhanced interface defined in SFF-8074i, SFP+ optical module has similar dimensions to SFP and complies with SFF-8472 (Digital Diagnostic Interface for Optical Transceivers), making the final users can monitor real SFP timing parameters such as optical output power, optical input power, temperature, laser bias current and transceiver supply voltage. SFP+ optical module is an upgrade of SFP optical module.
The SFP+ optical module has a form factor that is approximately 30% smaller than the 10-Gigabit Small Form-Factor Pluggable (XFP) form factor, uses less power, requires fewer components, and is less expensive, which is already smaller and less expensive than the XPAK. Because SFP+ is smaller in size than older XFP optics, it enables greater port density in network equipment.
An optical transceiver, commonly referred to as an optical module, is a crucial component in modern telecommunication systems and computer networks, enabling the transmission of data at high speeds by converting electrical signals into optical signals for seamless communication over fiber optic cables. More information can be found in optical transceiver wiki.
The 400G transceiver market is expected to experience rapid growth in the coming years, as data center operators seek to keep pace with escalating data traffic demands by upgrading to higher-speed networking solutions.
SFP+ optical modules are classified by application: SFP+ CWDM, SFP+ DWDM, SFP+ BIDI, dual-fiber SFP+, SFP+ direct-attached copper cable (SFP+ DAC), SFP+ active optical cable (SFP+ AOC). SFP+ transceivers are classified by data rate: 8.5Gb/s SFP+, 10Gb/s SFP+, 16Gb/s SFP+. SFP+ transceivers are classified by distance: 300m for SR, 220m for LRM, 10km or 20km for LR, 40km for ER, and 80km or 100km for ZR. Some SFP+ optical modules also use copper cables as interfaces. This will cause devices in the network to send data over shielded or unshielded twisted pair cables. Such copper cable interfaces are often used when the information to be transmitted only needs to cover a short distance, where it is more economical to use copper cables than fiber optic cables. We can provide a competitive 400g optical transceiver price.
The SFP+ optical module has a digital monitoring function, with which the performance of the SFP can be monitored in real-time. This feature can be used to monitor SFP performance parameters such as operating temperature and wavelength, supply voltage, optical input, and output, etc. These optical modules have a PCB that connects to an electrical connector designed for SFPs. The SFP+ optical module also has a 256-byte EEPROM memory. SFP+ transceivers are housed in metal housings and have low power consumption. They operate over a wide temperature range and support a large number of different types of cables. An improved version of the SFP standard called SFP+ can support transfer rates up to 10Gbps. Therefore, SFP+ optical modules will soon replace all existing interface standards in the network because of their compact, flexible, and economical design and high performance.
