Applications
Built for 100G Ethernet, data center interconnect and 5G transport networks, this QSFP28 module carries 103.125Gbps (4x 25.78Gbps) over SMF up to 2km per link. The Duplex LC interface and 1310nm optics match the standard cabling plant used in modern data halls, so existing trunks can be reused. For networks standardized on Cisco hardware, it is a drop-in equivalent of the QSFP-100G-FR-S.
Standards and Compatibility
This product is designed and tested to comply with 100G Lambda MSA 100G-FR Specification compliant. It is interoperable with Cisco equipment and serves as a direct equivalent to the Cisco part number QSFP-100G-FR-S.
Ordering Information
Order this product as QSFP-FR-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.
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.
Customization Service
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.
How We Ship
Most orders travel by international express and arrive within days; palletized freight by air or sea is used for volume orders. If you prefer, we ship on your DHL, UPS or FedEx account, or deliver to your appointed agent in China for onward consolidation.
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.
