Applications
In 40G Ethernet data center and enterprise network environments, the 40G QSFP+ QSFP-40G-ER4 40km 1310nm Duplex LC/UPC Module, Cisco delivers 44.6Gbps (4x 11.2Gbps) transmission over SMF with a reach of 40km. With its Duplex LC optical interface, the module works directly with the SMF infrastructure already installed in most facilities. Compatibility with Cisco systems is verified in our own test lab before shipment, so the unit works out of the box as an equivalent of QSFP-40G-ER4.
Standards and Compatibility
This product is designed and tested to comply with OTN OTU3, 40G Ethernet, SATA/SAS3, MSA Compliant. It is interoperable with Cisco equipment and serves as a direct equivalent to the Cisco part number QSFP-40G-ER4.
Ordering Information
Our part number for this module is QSFP-ER4-40G. 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.
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.
Reliability Control
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.
How We Pack
Transceivers and cables are individually protected against static and dust, then consolidated into sturdy cartons suitable for international courier shipment. For larger orders we shrink-wrap and strap cartons onto pallets. Tell us your warehouse or retail requirements and we will pack accordingly.
Factory Custom Capability
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.
