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. With its Duplex LC optical interface, the module works directly with the SMF infrastructure already installed in most facilities. 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.
Standards and Compatibility
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.
Ordering Information
To order, quote QSFP-LR4L-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.
Worldwide Delivery
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.
Quality Assurance
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.
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.
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.
