100G QSFP28 LR4 4x 25G NRZ MMA1L10-CR 1310nm 10km Duplex LC/UPC InfiniBand EDR, NVIDIA/Mellanox (Infiniband)

The 100G QSFP28 LR4 4x 25G NRZ MMA1L10-CR 1310nm 10km Duplex LC/UPC InfiniBand EDR, NVIDIA/Mellanox (Infiniband) is a QSFP28 optical transceiver delivering 103.125Gbps (4x 25.78Gbps) over SMF. Operating at 1310nm with a Duplex LC/UPC interface, it reaches 10km and is compliant with QSFP28 MSA, SFF-8636, IEEE 802.3‑2012, PSM4 MSA, CAUI-4. Built-in digital diagnostics give real-time access to operating parameters, making the module easy to deploy and maintain in 100G Ethernet, data center interconnect and 5G transport networks.

Built for 100G Ethernet, data center interconnect and 5G transport networks, this QSFP28 module carries 103.125Gbps (4x 25.78Gbps) over SMF up to 10km per link. 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 MMA1L10-CR. The link runs 4x 25G-NRZ modulation, which keeps it aligned with current 100G switch silicon.

Compliance: QSFP28 MSA, SFF-8636, IEEE 802.3‑2012, PSM4 MSA, CAUI-4. For projects standardized on NVIDIA/Mellanox Infiniband hardware, this product replaces the MMA1L10-CR 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.

To order, quote QSFP-LR4-100G-NVIDIA together with your quantity. Stock items ship quickly; for OEM orders we support custom labels, retail packing and vendor-specific coding, all handled in our own factory.

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.

Production samples and every outgoing batch pass through bit-error-rate measurement, temperature verification and plug-in compatibility checks on mainstream switches and routers. Because we are the manufacturer, any issue found in testing is fed back to the production line immediately instead of being passed on to customers.

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.

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.
