Applications
The 100G QSFP28 LR4 4x 25G NRZ MMA1L10-CR 1310nm 10km Duplex LC/UPC InfiniBand EDR, NVIDIA/Mellanox (Infiniband) is used in 100G Ethernet, data center interconnect and 5G transport networks, where it provides a 103.125Gbps (4x 25.78Gbps) link over SMF up to 10km. With its Duplex LC/UPC optical interface, the module works directly with the SMF infrastructure already installed in most facilities. It is interoperable with NVIDIA/Mellanox Infiniband platforms and replaces the NVIDIA/Mellanox Infiniband part MMA1L10-CR directly.
Standards and Compatibility
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.
Ordering Information
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.
Packing Details
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.
Custom-made Fiber Products
As a manufacturer serving the fiber optic industry since 1995, we have strong in-house manufacturing and design capability. From early GBIC, Xenpak and X2 modules to today's SFP, SFP+, QSFP, QSFP-DD and OSFP products, we grow together with the industry. OEM and custom-designed transceivers and cables are welcome, and our factory-direct pricing is very competitive compared with online retail stores.
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.
Our Testing Process
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.
