Applications
Built for CWDM metro access, enterprise and telecom edge networks, this QSFP28 module carries 103.125Gbps (4x 25.78Gbps) over SMF up to 2km per link. The Duplex LC/UPC interface and 1271nm, 1291nm, 1311nm and 1331nm optics match the standard cabling plant used in modern data halls, so existing trunks can be reused. It is interoperable with NVIDIA/Mellanox Infiniband platforms and replaces the NVIDIA/Mellanox Infiniband part MMA1L30-CM directly. The link runs 4x 25G-NRZ modulation, which keeps it aligned with current 100G switch silicon.
Standards and Compatibility
On the compatibility side, this unit is the practical equivalent of the NVIDIA/Mellanox Infiniband part MMA1L30-CM and works in NVIDIA/Mellanox Infiniband systems out of the box. Standards compliance covers QSFP28 MSA, SFF-8636, IEEE 802.3ba, IEEE 802.3bm, CAUI-4.
Ordering Information
Order this product as QSFP-CWDM4-100G-NVIDIA. Common models are stocked for fast dispatch. We can supply the module with neutral or customer-branded labels, and compatibility coding for a specific equipment vendor can be added at no extra process step.
How We Ship
Most orders travel by international express and arrive within days; palletized freight by air or sea is used for volume orders. If you prefer, we ship on your DHL, UPS or FedEx account, or deliver to your appointed agent in China for onward consolidation.
Quality and Testing
Every unit we ship is tested in our own test bed on mainstream switch and transport platforms before packing. Our test center has been fully upgraded, which sets us apart from other third party product providers: 10G, 40G, 100G, 200G and 400G transceivers and direct attach cables are verified on the latest top brand equipment, including selected original switches that can hardly be found elsewhere.
Package
Products are first packed into blister trays or self-sealed bags and then into cartons. Standard labels and marks are applied by default, and customized packing and labeling are available on request.
Factory Custom Capability
Working directly with the manufacturer means no middleman limits. We support OEM and ODM projects, custom cable assemblies, alternative packaging and compatibility coding for major equipment vendors, with engineering support from the same team that designs our standard products.
