Applications

Network architects choose the 100G QSFP28 CWDM4 4x 25G NRZ QSFP-100G-SM-SR 1310nm 2km Duplex LC/UPC Module, Cisco for CWDM metro access, enterprise and telecom edge networks: it runs 103.125Gbps (4x 25.78Gbps) over SMF and reaches 2km. Digital diagnostics report transmit power, receive power and temperature in real time, which simplifies commissioning and ongoing maintenance. For networks standardized on Cisco hardware, it is a drop-in equivalent of the QSFP-100G-CWDM4-SR.

Standards and Compatibility

This product is designed and tested to comply with QSFP28 MSA, SFF-8636, IEEE 802.3ba, IEEE 802.3bm, CAUI-4. It is interoperable with Cisco equipment and serves as a direct equivalent to the Cisco part number QSFP-100G-CWDM4-SR.

Ordering Information

To order, quote QSFP-CWDM4-100G-CISCO-2 together with your quantity. Stock items ship quickly; for OEM orders we support custom labels, retail packing and vendor-specific coding, all handled in our own factory.

OEM and Custom Orders

We have manufactured fiber optic connectivity products since 1995 and run our own production lines in Shenzhen. Beyond the standard catalog we build to order: special cable lengths, custom connector combinations, vendor-specific compatibility coding and private labeling. Send us your requirement and our engineers will quote a practical solution.

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.

Packaging Options

Default packaging is simple and protective: sealed bag, blister tray, export carton. For OEM customers we also offer white-label packing, custom printed boxes and per-unit labeling with your own part numbers, so the goods can go straight into your sales channel.
