Applications
Network architects choose the 40G QSFP+ QSFP-40G-LR4-20 20km 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 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
This product is designed and tested to comply with QSFP+ MSA, SFF-8436. It is interoperable with Cisco equipment and serves as a direct equivalent to the Cisco part number QSFP-40G-LR4-20.
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.
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.
Package
Products are first packed into blister trays or self-sealed bags and then into cartons. Standard labels and marks are applied by default, and customized packing and labeling are available on request.
Custom-made Fiber Products
As a manufacturer serving the fiber optic industry since 1995, we have strong in-house manufacturing and design capability. From early GBIC, Xenpak and X2 modules to today's SFP, SFP+, QSFP, QSFP-DD and OSFP products, we grow together with the industry. OEM and custom-designed transceivers and cables are welcome, and our factory-direct pricing is very competitive compared with online retail stores.
Delivery
Goods are normally sent by courier such as DHL, UPS, FedEx, TNT or EMS; air and sea freight are also available on request. Commonly used items are kept in stock for immediate shipment, and out-of-stock items are usually delivered within a few working days. We can also ship on your courier account or hand goods to your appointed forwarder.
