Applications
The C-band Tunable 10G DWDM SFP+ 50GHz, 40km ER Industrial, 80 Channels, Cisco is used in data center interconnect, metro transport and carrier aggregation networks, where it provides a 11.3Gbps link over SMF up to 40km. With its Duplex LC/UPC optical interface, the module works directly with the SMF infrastructure already installed in most facilities. Our factory programs the compatibility coding for your switch brand before shipment and verifies each unit on real host equipment.
Standards and Compatibility
This product is designed and tested to comply with SFF-8432 Rev5.2a, SFF-8472 Rev12.3,SFF-8690 Rev1.5, SFF-8431 Rev4.1a. It plugs into any standards-based SFP+ port, and compatibility coding for specific switch or router brands can be done in our factory before shipment.
Ordering Information
Order this product as DW-SFP10G40-C-I. Common models are stocked for fast dispatch. We can supply the module with neutral or customer-branded labels, and compatibility coding for a specific equipment vendor can be added at no extra process step.
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.
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.
