Applications

The 40G QSFP+ QSFP-40G-ER4 40km 1310nm Duplex LC/UPC Module, Cisco is used in 40G Ethernet data center and enterprise network environments, where it provides a 44.6Gbps (4x 11.2Gbps) link over SMF up to 40km. 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-40G-ER4 directly.

Standards and Compatibility

Compliance: OTN OTU3, 40G Ethernet, SATA/SAS3, MSA Compliant. For projects standardized on Cisco hardware, this product replaces the QSFP-40G-ER4 directly, with identical fit and function. 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.

Ordering Information

To order, quote QSFP-ER4-40G 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.

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.

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.

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.

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.
