Types of SFP+ Modules in Market

The SFP+ transceiver module is a compact hot-pluggable transceiver that is used for telecommunication. It supports 10 Gbps for the next generation Gigabit Ethernet applications. These transceivers are an improvement to the previous SFP cables making them be smaller and thus providing higher density per line card.The SFP+ modules are ideally suited for the datacom and storage area network applications that are based on the Fiber Channel Standards. The SFP+ modules support 10GBase Ethernet and the OTU2/OTU2e, and it supports the Digital Diagnostic Monitor (DDM) function and the provision of the flexibility of interface choice.There are different kinds of the SFP+ modules such as - SFP+ MM 300m, SFP+ 10 km, SFP+ 40 km, CWDM SFP+, DWDM SFP+ and the BiDi SFP+. Types of SFP+ Transceivers10G SFP+They are designed for the high performance integrated duplex data transmission over the single mode optical fiber. The 10G SFP+ transceivers are fully compliant to the SFP+ MSA and are hot swappable. They meet the requirements for the Ethernet standards and are quite suitable for the interconnections of the 10G Ethernet environments.DWDM SFP+The DWDM SFP+ transceivers operate at nominal DWDM wavelengths on the 100GHz grid as defined by the ITU-T 694.1 standards. The transceivers are specifically designed for the carriers and the large enterprises that require scalable, flexible and cost-effective systems to facilitate multiplexing, transportation and the protection of the high-speed data to facilitate transmissions across various networking platforms.CWDM SFP+CWDM SFP+ modules are pluggable optical transceivers that are designed to meet the specific networking protocols to meet the media requirements. The digital diagnostic are available through the I2C. The module is designed for the single mode fiber and operates at a nominal wavelength of the CWDM wavelength. The CWDM characteristics are quite in compliance with the wavelength parameters that are specified in the ITU standards. The transceivers support the transmission of data to lengths ranging from 10km, 40km and 80km.BIDI SFP+The BiDi SFP+ transceivers are designed for the bi-directional 10G serial optical data communication. The transceiver consists of two sections. One section makes use of the multiple quantum well 1330 (1270) nm DFB laser and the receiver section uses and integrated 1270 (1330) nm detector preamplifier that is mounted on an optical header.

The standard applications for the SFP+ modules are based on the 8G Fiber Channel, 10G Ethernet and the 10G Fiber Channel where the electrical interface host the board in a standardized serial interface.
