The 40G QSFP+ 10km 1310nm Duplex LC/UPC Industrial Module, Cisco is used in 40G Ethernet data center and enterprise network environments, where it provides a 41.25Gbps (4x 10.3125Gbps) link over SMF up to 10km. With its Duplex LC optical interface, the module works directly with the SMF infrastructure already installed in most facilities. If your project needs a specific vendor coding or custom label, our production line handles it as a routine step before packing.
Compliance: QSFP+ MSA, SFF-8436, IEEE 802.3ba. 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.
Our part number for this module is QSFP-LR4-40G-I. 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.
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.
Each unit is sealed in an anti-static bag, cushioned in a blister tray and boxed in an export-grade carton. Outer cartons carry handling marks and can be palletized for air or sea freight. If your project requires retail boxes, barcodes or your own brand on the label, we can arrange that as well.
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.
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.
