Applications
The 10G SFP+ SFP-10G-ER40-I 40km 1310nm Duplex LC/UPC Industrial Module, Cisco is used in 10G Ethernet data center and enterprise network environments, where it provides a 10.52Gbps link over SMF up to 40km. Digital diagnostics report transmit power, receive power and temperature in real time, which simplifies commissioning and ongoing maintenance. 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 SFP-10G-ER40-I.
Standards and Compatibility
On the compatibility side, this unit is the practical equivalent of the Cisco part SFP-10G-ER40-I and works in Cisco systems out of the box. Standards compliance covers SFP+ MSA, CPRI, eCPRI, IEEE802.3ae, SFF-8432, SFF-8431, 10GFC, FC-PI-4.
Ordering Information
Order this product as SFP-10GER-31-I-CISCO. 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.
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.
Package
Products are first packed into blister trays or self-sealed bags and then into cartons. Standard labels and marks are applied by default, and customized packing and labeling are available on request.
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.
