40G optical transceiver is packaged in QSFP+. 40g qsfp+ transceiver has four independent full-duplex transmission and reception channels, and the transmission rate of 40G can be realized at the same time. 40G qsfp transceiver can provide high-speed, high-density, low-power, low-cost 40G Ethernet high-speed interconnection for data centers, high-performance computer networks and telecom operators, etc.
40G optical transceivers can be divided into 850nm/1310nm/ according to working wavelength, such as QSFP 40G 850nm 300m 40g mpo. There are multi-mode and single-mode optical modules, MPO and LC interface, the transmission distance support to 150m/300m/10km/ 30km/40km/80km.

The MPO transceiver refers to an optical transceiver with an MPO interface. It must be used with the fiber jumper of MPO interface. The MPO interface is divided into male and female, which must be used together. Generally, the interface type of the optical transceiver is MPO male, connect to the fiber jumper of MPO female.
QSFP is the abbreviation of Quad Small Form-factor Pluggable, that is, four-channel small form-factor pluggable optical transceiver. QSFP was born to meet the demand of higher-density high-speed pluggable solutions. It has a transmission rate of 40Gbps.
QSFP+ is an upgraded version of QSFP. Strictly speaking, there is no difference. Both of them can support 4 channels of transmission at the same time, each channel has a data rate of 10Gbit/s, to achieve a 40Gbps transmission rate through 4 channels. QSFP+ optical transceivers can be used in deploying 40G networks, thereby increasing port density and saving costs effectively.
40G optical transceiver s have different wavelengths, transmission distances and interfaces. 40G direct connection solution
①SR4-SR4: direct connection via multimode optical fiber with MPO/MTP interface
②LR4-LR4: Connect through single-mode optical fiber with LC interface
③PSM4-PSM4: Connect via single-mode optical fiber with MPO/MTP interface.
