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. With its Duplex LC optical interface, the module works directly with the SMF infrastructure already installed in most facilities. It is interoperable with Cisco platforms and replaces the Cisco part QSFP-40G-LR4-20 directly.
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
To order, quote QSFP-ELR4-40G 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.
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.
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.
