In 40G Ethernet data center and enterprise network environments, the 40G QSFP+ 10km 1310nm Duplex LC/UPC Industrial Module, Cisco delivers 41.25Gbps (4x 10.3125Gbps) transmission over SMF with a reach of 10km. The Duplex LC interface and 1310nm optics match the standard cabling plant used in modern data halls, so existing trunks can be reused. If your project needs a specific vendor coding or custom label, our production line handles it as a routine step before packing.
This product is designed and tested to comply with QSFP+ MSA, SFF-8436, IEEE 802.3ba. It plugs into any standards-based QSFP+ port, and compatibility coding for specific switch or router brands can be done in our factory before shipment.
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.
From incoming component inspection to final burn-in, quality is controlled at each step of production. Finished units are verified on real networking equipment in our compatibility lab, and test records are kept per batch so that any field question can be traced back quickly.
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.
Working directly with the manufacturer means no middleman limits. We support OEM and ODM projects, custom cable assemblies, alternative packaging and compatibility coding for major equipment vendors, with engineering support from the same team that designs our standard products.
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.
