FAQs

What is the 400G QSFP112 CWDM4 Transceiver?
This high-performance transceiver module is intended for 400 Gigabit Ethernet (GbE) applications in data centers. It uses Coarse Wavelength Division Multiplexing (CWDM4) technology to send and receive data over SMF.
What makes CWDM4 better than 400G SR8 or 400G DR4?
Compared to CWDM4’s 2 kilometers, SR8 and DR4 enable 400 GbE but have shorter reach limits (100 meters and 500 meters, respectively). CWDM4 optimizes medium-distance data center interconnects for reach and cost.

Will the 400G QSFP112 CWDM4 transceiver work with the 100G QSFP28?
Different form factors, electrical connectors, and data speeds make these transceivers incompatible. A 400 GbE-specific QSFP112 port is needed.

What wavelengths does the transceiver use for CWDM?
Transceivers use CWDM wavelengths of 1271nm, 1291nm, 1311nm, and 1331nm.

Does the transceiver need a network switch configuration?
No extra configuration is usually needed. Some network switches require CWDM mode or other configurations for maximum performance. Refer to your switch’s manual for details.

How can I monitor 400G QSFP112 CWDM4 Transceiver health?
The transceiver’s CMIS 5.0 management interface lets you monitor temperature, laser bias current, and optical power with compatible network management software.
