We are planning a 50+ unit rollout across our campus backbone. Do you offer volume tier discounts or B2B project pricing?

Absolutely. We provide tiered volume discounts starting at 10 units, with deeper pricing brackets for 50, 100, and 500+ unit deployments. You can request a custom quote directly through the product page or contact our enterprise sales team to receive a tailored commercial invoice with project-specific tier pricing.

Can these 100G QSFP28 CWDM4 modules be pre-coded for our mixed switch environment with Cisco Nexus, Arista, and Juniper hardware?

Yes. We offer customized EEPROM vendor coding for all major OEMs including Cisco, Arista, Juniper, Dell, NVIDIA/Mellanox, and Edgecore. When placing your order or requesting a quote, specify your target switch models and OS versions, and each unit will be pre-coded and tested for seamless native recognition and DDM support with no CLI compatibility warnings.

Does this transceiver comply with official CWDM4 MSA and IEEE 100G Ethernet standards?

Yes. The module is fully compliant with the CWDM4 MSA technical specification, IEEE 802.3bm 100GBASE-CWDM4, SFF-8665, and SFF-8636 management interface standards. It is also fully RoHS compliant, CE/FCC certified, and meets Class 1 laser safety requirements.

What type of fiber optic patch cable and connector interface do I need to connect this 2km CWDM4 transceiver?

This module requires standard Duplex LC Single-Mode Fiber (SMF/OS2, 9/125μm). It uses two fibers (one TX, one RX) carrying four CWDM wavelengths (1271, 1291, 1311, 1331nm) via internal optical multiplexing, eliminating the need for bulky MTP/MPO ribbon cables.
