Applications
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. Digital diagnostics report transmit power, receive power and temperature in real time, which simplifies commissioning and ongoing maintenance. For networks standardized on Cisco hardware, it is a drop-in equivalent of the WSP-Q40GLR4L.
Standards and Compatibility
This product is designed and tested to comply with 40G Ethernet, Fibre Channel, SATA/SAS3, MSA Compliant. It is interoperable with Cisco equipment and serves as a direct equivalent to the Cisco part number WSP-Q40GLR4L.
Ordering Information
Our part number for this module is QSFP-LR4L-40G. When ordering, just let us know the quantity and whether you need the compatibility coding for a particular switch brand; labeling and packaging can also follow your channel requirements.
Logistics
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.
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.
How We Pack
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.
Built to Your Spec
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.
