Network architects choose the 100G QSFP28 CWDM4 4x 25G NRZ MMA1L30-CM 1310nm 2km Duplex LC/UPC InfiniBand EDR, NVIDIA/Mellanox (Infiniband) for CWDM metro access, enterprise and telecom edge networks: it runs 103.125Gbps (4x 25.78Gbps) over SMF and reaches 2km. 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. For networks standardized on NVIDIA/Mellanox Infiniband hardware, it is a drop-in equivalent of the MMA1L30-CM.

Compliance: QSFP28 MSA, SFF-8636, IEEE 802.3ba, IEEE 802.3bm, CAUI-4. For projects standardized on NVIDIA/Mellanox Infiniband hardware, this product replaces the MMA1L30-CM directly, with identical fit and function. Every unit's EEPROM coding and link behavior are verified on real host equipment in our lab, so what arrives at your site is ready to use.

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.

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.

Standard packing is an anti-static bag plus blister protection, with cartons sized to keep products from moving in transit. We apply our standard labels by default; neutral packing or customer-branded labels, part number stickers and serial barcodes are all available on request.

We have manufactured fiber optic connectivity products since 1995 and run our own production lines in Shenzhen. Beyond the standard catalog we build to order: special cable lengths, custom connector combinations, vendor-specific compatibility coding and private labeling. Send us your requirement and our engineers will quote a practical solution.

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.
