Description
QSFP-100G-CWDM4H transceiver is a single mode, 4-channel (CWDM4), QSFP28 optical transceiver designed for use in 100 Gigabit Ethernet (GbE) links on up to 2km of single mode fiber. It is also qualified for use in InfiniBand EDR end-to-end systems.
The module converts 4 input channels of 25Gb/s electrical data to 4 channels of CWDM optical signals and then multiplexes them into a single fiber, using a nominal wavelength of 1310nm, for 100Gb/s optical transmission. Reversely on the receiver side, the module de-multiplexes a 100Gb/s optical input into 4 channels of CWDM optical signals and then converts them to 4 output channels of electrical data.
It is compliant with the QSFP28 MSA, IEEE 802.3bm CAUI-4. Digital diagnostic functions are available via the I2C interface, as specified by the QSFP28 MSA.
Rigorous production testing ensures the best out-of-the-box installation experience, performance and durability.
