In order to meet the demand for high-speed Ethernet, cloud computing, virtual data center and other services, the transformation of communication transmission network from 10G to 40G is irresistible. The main packaging type of 40G optical module is QSFP+, which conforms to SCSI, 40G Ethernet, 40G Infiniband and other standards, and greatly meets the market demand for high density and high speed. Next, we will introduce the QSFP-40G-ESR4 optical module
Product description:
The QSFP-40G-ESR4 optical module parallels the 40Gb/s four channel small pluggable optical module, which improves the port density and reduces the total system cost. Four independent transmit and receive channels are provided. Each channel can operate at 10Gb/s. The maximum transmission distance is 300m on OM3 multimode fiber and 400m on OM4 multimode fiber.
Product characteristics:
▲ High reliability 850nm VCSEL technology
▲ Electric plug
▲ Conform to SFF-8436 standard of digital diagnosis
▲ Operating temperature range of enclosure: 0 ° C to 70 ° C
▲ Power consumption<1.5 W
Application scenario:
40G QSFP+optical module with 40G switch is the best choice. The transmission wavelength of QSFP-40G-ESR4 optical module is 850nm, which can be connected with MPO/MTP optical fiber jumper (high-density optical fiber jumper). The supplied optical module products can meet the cabling needs of high-density data centers, and build a cost-effective optical network system for users.
What are the collocation schemes of the S6720S switch and optical modules?
Huawei S6720S-26Q-LI-24S-A switch belongs to 10 Gigabit Ethernet switch, with transmission rate of 100/1000/10000 Mbps, 40000 Mbps and 24 × 10GE SFP+ports and 2 × 40GE QSFP+port. So it is matched with 10G SFP+optical module and 40G QSFP+optical module.
Huawei S6720S switch and 40G QSFP+optical module matching scheme:
The 40G optical module can support hot plug, the maximum speed is 41.2Gb/s, the power consumption is less than 3.5W, and it can support the DDM digital diagnosis monitoring function. With Huawei S6720S-26Q-LI-24S-A switch 2 × 40GE QSFP+ports are used together. The QSFP-40G-LR4 optical module is used in the following figure, and the transmission distance can reach 10km with LC optical fiber jumper.
The 10G optical module can support hot plug, the maximum transmission distance can reach 80KM, and supports DDM digital diagnosis monitoring function. With Huawei S6720S-26Q-LI-24S-A switch 24 × 10GE SFP+ports are used together. The SFP-10G-ZR optical module is used in the figure below, and the transmission distance with LC optical fiber jumper can reach 80KM, which is suitable for long-distance transmission applications.
