Applications
In 40G Ethernet data center and enterprise network environments, the 40G QSFP+ QSFP-40G-LR4-20 20km 1310nm Duplex LC/UPC Module, Cisco delivers 41.2Gbps (4x 10.3Gbps) transmission over SMF with a reach of 20km. 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 QSFP-40G-LR4-20.
Standards and Compatibility
On the compatibility side, this unit is the practical equivalent of the Cisco part QSFP-40G-LR4-20 and works in Cisco systems out of the box. Standards compliance covers QSFP+ MSA, SFF-8436.
Ordering Information
Order this product as QSFP-ELR4-40G. 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.
Packing Details
Standard packing is an anti-static bag plus blister protection, with cartons sized to keep products from moving in transit. We apply our standard labels by default; neutral packing or customer-branded labels, part number stickers and serial barcodes are all available on request.
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.
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.
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.
