Built for CWDM metro access, enterprise and telecom edge networks, this QSFP28 module carries 103.125Gbps (4x 25.78Gbps) over SMF up to 2km per link. 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-CWDM4-S.

On the compatibility side, this unit is the practical equivalent of the Cisco part QSFP-100G-CWDM4-S and works in Cisco systems out of the box. Standards compliance covers QSFP28 MSA, SFF-8636, IEEE 802.3ba, IEEE 802.3bm, CAUI-4.

Order this product as QSFP-CWDM4-100G-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.

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.

Because we are the factory, customization is straightforward: non-standard lengths, different jacket materials, specific polarity or breakout wiring, and compatibility programming for particular switch brands are all routine work for us. Small trial orders are accepted so you can verify quality before scaling up.

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.

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.
