The 40g qsfp + optical module is a four channel small pluggable optical module with a transmission rate of 40Gbps. It can realize the interconnection between network equipment (such as switches, routers, media converters and other similar equipment) and optical or copper cables. Its structure is more compact than CFP optical module, so it is more suitable for applications with high port density. The common optical modules can be divided into 40gbase-sr4 optical module, 40gbase-lr4 optical module, 40gbase-er4 optical module and 40g LR4 PSM optical module.
The interface of 40g Sr4 qsfp + optical module is MPO / MTP. It has four independent full duplex channels, which are often used with multimode fiber. The transmission distance when used with OM3 fiber jumper is 100m, and when used with OM4 fiber jumper, the transmission distance is 150m.
The interface of 40g LR4 qsfp + optical module is LC duplex, which has the advantages of high density, high speed, large capacity, low cost and low power consumption. It is generally used with LC single-mode fiber jumper, and the maximum transmission distance can reach 10km.
The interface of 40g LR4 PSM optical module is MPO / MTP, which adopts parallel single mode (PSM) and 4-channel parallel design MPO / MTP interface. The transmission distance is 10km, which has the characteristics of high port density and low cost.
The 40g Er4 qsfp + optical module is the same as the 40g LR4 qsfp + optical module, and is generally used with LC single-mode fiber. The difference is that 40g Er4 The qsfp + optical module converts four 10g data input channels into four CWDM optical signal channels, with the speed of each channel up to 11.2gbps, and multiplexes them into a single channel for 40g optical transmission. It is mainly used in 40gbase-er4 Ethernet link, Infiniband QDR and DDR interconnection, and customer 40g telecommunication connection.
40g qsfp + optical module:
1. Semiconductor packaging technology, built-in four lasers, detectors, can support the needs of high-density single board customers.
2. When the bandwidth needs to be increased, network operators can add new qsfp + optical modules without interrupting network services.
3. The power consumption is less than 3.5W, while that of the old CFP module is 8W.
4. The transmission distance can be up to 10km in the client optical fiber transmission applications of enterprise network, LAN, San and telecommunication network.
HTF provides a variety of 40g qsfp + optical modules with high cost performance and strong practicability. It can also provide reliable system solutions to help users set up data center access network more conveniently and flexibly.
