Applications

The 100G QSFP28 CWDM4 4x 25G NRZ MMA1L30-CM 1310nm 2km Duplex LC/UPC InfiniBand EDR, NVIDIA/Mellanox (Infiniband) is used in CWDM metro access, enterprise and telecom edge networks, where it provides a 103.125Gbps (4x 25.78Gbps) link over SMF up to 2km. The Duplex LC/UPC interface and 1271nm, 1291nm, 1311nm and 1331nm optics match the standard cabling plant used in modern data halls, so existing trunks can be reused. 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.

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

To order, quote QSFP-CWDM4-100G-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.

OEM and Custom Orders

We have manufactured fiber optic connectivity products since 1995 and run our own production lines in Shenzhen. Beyond the standard catalog we build to order: special cable lengths, custom connector combinations, vendor-specific compatibility coding and private labeling. Send us your requirement and our engineers will quote a practical solution.

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.

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 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.
