Applications
In 100G Ethernet, data center interconnect and 5G transport networks, the 100G QSFP28 LR4 4x 25G NRZ MMA1L10-CR 1310nm 10km Duplex LC/UPC InfiniBand EDR, NVIDIA/Mellanox (Infiniband) delivers 103.125Gbps (4x 25.78Gbps) transmission over SMF with a reach of 10km. The Duplex LC/UPC interface and 1310nm 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 MMA1L10-CR directly.
Standards and Compatibility
On the compatibility side, this unit is the practical equivalent of the NVIDIA/Mellanox Infiniband part MMA1L10-CR and works in NVIDIA/Mellanox Infiniband systems out of the box. Standards compliance covers QSFP28 MSA, SFF-8636, IEEE 802.3‑2012, PSM4 MSA, CAUI-4.
Ordering Information
Our part number for this module is QSFP-LR4-100G-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.
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.
Tested Before Shipment
We do not ship untested stock. Each transceiver and cable is powered up in our test racks, checked for link stability, transmit power, receiver sensitivity and diagnostic readouts, and only then packed for delivery. This factory-level testing is one reason network integrators keep reordering from us year after year.
Packaging
Each unit is sealed in an anti-static bag, cushioned in a blister tray and boxed in an export-grade carton. Outer cartons carry handling marks and can be palletized for air or sea freight. If your project requires retail boxes, barcodes or your own brand on the label, we can arrange that as well.
Built to Your Spec
Our product line has grown with the industry for three decades, from GBIC-era modules to today's 800G and 1.6T interconnects. If the exact configuration you need is not listed, we can usually build it: custom lengths, mixed connector breakouts, OEM branding and project-specific firmware coding are all supported.
