Network architects choose the 40G QSFP+ WSP-Q40GLR4L 2km 1310nm Duplex LC/UPC Module, Cisco for 40G Ethernet data center and enterprise network environments: it runs 41.2Gbps (4x 10.3Gbps) over SMF and reaches 2km. 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 WSP-Q40GLR4L.

Compliance: 40G Ethernet, Fibre Channel, SATA/SAS3, MSA Compliant. For projects standardized on Cisco hardware, this product replaces the WSP-Q40GLR4L 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.

Order this product as QSFP-LR4L-40G. Common models are stocked for fast dispatch. We can supply the module with neutral or customer-branded labels, and compatibility coding for a specific equipment vendor can be added at no extra process step.

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.

We ship to customers around the world every week. Express couriers handle most orders door to door in a few days; larger consignments go by air or sea to keep freight costs down. Tracking information is provided for every shipment, and we are flexible on shipping accounts and forwarders.

Before any product leaves our factory it goes through optical performance testing, compatibility verification on real switch platforms and a final visual inspection. Our in-house test lab holds a wide range of current and legacy switches from major brands, so interoperability is proven on the actual equipment your network uses rather than assumed from paper specifications.

Transceivers and cables are individually protected against static and dust, then consolidated into sturdy cartons suitable for international courier shipment. For larger orders we shrink-wrap and strap cartons onto pallets. Tell us your warehouse or retail requirements and we will pack accordingly.
