Applications
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. Digital diagnostics report transmit power, receive power and temperature in real time, which simplifies commissioning and ongoing maintenance. Compatibility with NVIDIA/Mellanox Infiniband systems is verified in our own test lab before shipment, so the unit works out of the box as an equivalent of MMA1L30-CM. The link runs 4x 25G-NRZ modulation, which keeps it aligned with current 100G switch silicon.
Standards and Compatibility
This product is designed and tested to comply with QSFP28 MSA, SFF-8636, IEEE 802.3ba, IEEE 802.3bm, CAUI-4. It is interoperable with NVIDIA/Mellanox Infiniband equipment and serves as a direct equivalent to the NVIDIA/Mellanox Infiniband part number MMA1L30-CM.
Ordering Information
Our part number for this module is QSFP-CWDM4-100G-NVIDIA. When ordering, just let us know the quantity and whether you need the compatibility coding for a particular switch brand; labeling and packaging can also follow your channel requirements.
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.
Delivery
Goods are normally sent by courier such as DHL, UPS, FedEx, TNT or EMS; air and sea freight are also available on request. Commonly used items are kept in stock for immediate shipment, and out-of-stock items are usually delivered within a few working days. We can also ship on your courier account or hand goods to your appointed forwarder.
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.
