Applications
In 100G Ethernet, data center interconnect and 5G transport networks, the 100G QSFP28 4W20 4x 25G NRZ 1310nm 20km Duplex LC /UPC Industrial Module, Cisco delivers 103.125Gbps (4x 25.78Gbps) transmission over SMF with a reach of 20km. The Duplex LC interface and 1310nm optics match the standard cabling plant used in modern data halls, so existing trunks can be reused. It is interoperable with Cisco platforms and replaces the Cisco part QSFP-4W20-100G-I directly. The link runs 4x 25G-NRZ modulation, which keeps it aligned with current 100G switch silicon.
Standards and Compatibility
Compliance: QSFP28 MSA,IEEE 802.3-2018,4WDM-20,SFF-8661,SFF-8636. For projects standardized on Cisco hardware, this product replaces the QSFP-4W20-100G-I 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.
Ordering Information
Our part number for this module is QSFP-4W20-100G-I. When ordering, just let us know the quantity and whether you need the compatibility coding for a particular switch brand; labeling and packaging can also follow your channel requirements.
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.
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.
