Applications
Network architects choose the 100G QSFP28 4W20 4x 25G NRZ 1310nm 20km Duplex LC /UPC Industrial Module, Cisco for 100G Ethernet, data center interconnect and 5G transport networks: it runs 103.125Gbps (4x 25.78Gbps) over SMF and reaches 20km. With its Duplex LC optical interface, the module works directly with the SMF infrastructure already installed in most facilities. 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-4W20-100G-I.
Standards and Compatibility
On the compatibility side, this unit is the practical equivalent of the Cisco part QSFP-4W20-100G-I and works in Cisco systems out of the box. Standards compliance covers QSFP28 MSA,IEEE 802.3-2018,4WDM-20,SFF-8661,SFF-8636.
Ordering Information
To order, quote QSFP-4W20-100G-I 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.
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.
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.
Packing Details
Standard packing is an anti-static bag plus blister protection, with cartons sized to keep products from moving in transit. We apply our standard labels by default; neutral packing or customer-branded labels, part number stickers and serial barcodes are all available on request.
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.
