Custom 40G QSFP+ CWDM4 Module, Single-Mode

Product Overview

Targeting the massive Data Center Interconnect (DCI) demands of hyper-scale cloud providers, the 40G QSFP+ CWDM4 Module offers a perfect middle-ground between distance capability and hardware cost. Adhering to the CWDM4 MSA multi-source agreement, this unit modulates four 10Gbps data streams onto four continuous wavelengths separated by a 20nm spacing. It delivers high-speed data up to 2 kilometers over a single duplex SMF jumper, entirely avoiding the exorbitant costs associated with long-haul LR4 modules.

Frequently Asked Questions

Q: Why choose CWDM4 over LR4 if both are for single-mode fiber?
A: CWDM4 is significantly cheaper and consumes less power than LR4. If your switch-to-switch link is under 2km, CWDM4 is the most economical choice for data center interconnects.

Q: Do I need to enable FEC on my switch for this to work?
A: Yes, CWDM4 technology generally requires RS-FEC (Forward Error Correction) to be enabled on the host switch to ensure zero packet loss.

Q: Will this module run too hot in a fully populated switch?
A: No. We control the power consumption of our CWDM4 modules to under 3.5W. It meets the standard QSFP+ MSA thermal specifications.
