Network architects choose the 100G QSFP28 ERL 4x 25G NRZ QSFP-100G-ERL-S 1310nm 25km Duplex LC/UPC Single Lambda Module, Cisco for 100G Ethernet, data center interconnect and 5G transport networks: it runs 106.25Gbps over SMF and reaches 25km. 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-ERL-S. The link runs 4x 25G-NRZ modulation, which keeps it aligned with current 100G switch silicon.

Compliance: CEI-28G-VSR, QSFP28 MSA, SFF-8636. For projects standardized on Cisco hardware, this product replaces the QSFP-100G-ERL-S 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.

Order this product as QSFP-ERL-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.

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.

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.

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.

Our warehouse keeps fast-moving transceivers and cables ready for same-week dispatch. Courier, air freight and sea freight options are all available depending on your budget and schedule, and we consolidate multiple items into one shipment whenever it saves you cost.
