Built for 40G Ethernet data center and enterprise network environments, this QSFP+ module carries 41.2Gbps (4x 10.3Gbps) over SMF up to 20km per link. The Duplex LC interface and 1310nm optics match the standard cabling plant used in modern data halls, so existing trunks can be reused. Compatibility with Cisco systems is verified in our own test lab before shipment, so the unit works out of the box as an equivalent of QSFP-40G-LR4-20.

This product is designed and tested to comply with QSFP+ MSA, SFF-8436. It is interoperable with Cisco equipment and serves as a direct equivalent to the Cisco part number QSFP-40G-LR4-20.

To order, quote QSFP-ELR4-40G 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.

Our warehouse keeps fast-moving transceivers and cables ready for same-week dispatch. Courier, air freight and sea freight options are all available depending on your budget and schedule, and we consolidate multiple items into one shipment whenever it saves you cost.

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.

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.

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.
