Applications
In 100G Ethernet, data center interconnect and 5G transport networks, the 100G QSFP28 SR4 4x 25G NRZ MMA1B00-E100 850nm 100m MPO-12/UPC InfiniBand EDR, NVIDIA/Mellanox (Infiniband) delivers 103.125Gbps (4x 25.78Gbps) transmission over MMF with a reach of 70m@OM3/100m@OM4. With its MTP/MPO-12 optical interface, the module works directly with the MMF infrastructure already installed in most facilities. 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 MMA1B00-E100. The link runs 4x 25G-NRZ modulation, which keeps it aligned with current 100G switch silicon.
Standards and Compatibility
Compliance: QSFP28 MSA, SFF-8636, IEEE 802.3bm, CAUI-4. For projects standardized on NVIDIA/Mellanox Infiniband hardware, this product replaces the MMA1B00-E100 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-SR4-100G-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.
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.
Reliability Control
From incoming component inspection to final burn-in, quality is controlled at each step of production. Finished units are verified on real networking equipment in our compatibility lab, and test records are kept per batch so that any field question can be traced back quickly.
Packaging Options
Default packaging is simple and protective: sealed bag, blister tray, export carton. For OEM customers we also offer white-label packing, custom printed boxes and per-unit labeling with your own part numbers, so the goods can go straight into your sales channel.
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.
