Knowledge Base + 2023.12.04

The standard operating temperature range of QSFP28 transceiver commercial version is 0°C to 70°C; that of industrial version is -45°C to +85°C;

Commercial version products are generally applied. There are also some data centers that use products with operating temperatures ranging from 20°C to 50°C to reduce costs.

Walsun100G QSFP28 transceivers include SR4,CWDM4, LR4 and ER4 lite, adopt MPO or LC interface and compatible with IEEE802.3bm, SFF-8636 and other standards.They have the characteristics of low power consumption, small size and high speed, and is beneficial to increasing the capacity of the data center, improve the port density and reduce the power consumption. It is widely applied in large data center, 100G Ethernet, ITU-T OTU4 and other environments.
