Applications
In 100G Ethernet, data center interconnect and 5G transport networks, the 100G QSFP28 ESR4 4x 25G NRZ QSFP-100G-SR4-S 850nm 300m MPO-12/UPC Module, Cisco delivers 103.125Gbps (4x 25.78Gbps) transmission over MMF with a reach of 200m@OM3/300m@OM4. 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 QSFP-100G-SR4-S.
Standards and Compatibility
On the compatibility side, this unit is the practical equivalent of the Cisco part QSFP-100G-SR4-S and works in Cisco systems out of the box. Standards compliance covers IEEE 802.3bm, QSFP28 MSA, SFF-8665, SFF-8636, SFF-8679.
Ordering Information
Order this product as QSFP-ESR4-100G. 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.
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.
Our Testing Process
Production samples and every outgoing batch pass through bit-error-rate measurement, temperature verification and plug-in compatibility checks on mainstream switches and routers. Because we are the manufacturer, any issue found in testing is fed back to the production line immediately instead of being passed on to customers.
