Applications
Built for 40G Ethernet data center and enterprise network environments, this QSFP+ module carries 44.6Gbps (4x 11.2Gbps) over SMF up to 10km per link. Digital diagnostics report transmit power, receive power and temperature in real time, which simplifies commissioning and ongoing maintenance. It is interoperable with Cisco platforms and replaces the Cisco part QSFP-40GE-LR4 directly.
Standards and Compatibility
This product is designed and tested to comply with OTN OTU3, 40G Ethernet, Fiber Channel, SATA/SAS3, MSA Compliant. It is interoperable with Cisco equipment and serves as a direct equivalent to the Cisco part number QSFP-40GE-LR4.
Ordering Information
Our part number for this module is QSFP-LR4-40G. 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.
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.
Our Testing Process
Production samples and every outgoing batch pass through bit-error-rate measurement, temperature verification and plug-in compatibility checks on mainstream switches and routers. Because we are the manufacturer, any issue found in testing is fed back to the production line immediately instead of being passed on to customers.
Packaging Options
Default packaging is simple and protective: sealed bag, blister tray, export carton. For OEM customers we also offer white-label packing, custom printed boxes and per-unit labeling with your own part numbers, so the goods can go straight into your sales channel.
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.
