Applications
The 100/112G QSFP28 ER4&OTU4 4x 25G NRZ QSFP-100/112G-ER4 1310nm 40km Duplex LC/UPC Dual Rate Module, Cisco is used in OTN transport, carrier metro and long-haul aggregation networks, where it provides a Dual Rate 103.1Gbps and 112Gbps link over SMF up to 40km. 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-100/112G-ER4. The link runs 4x 25G-NRZ modulation, which keeps it aligned with current 100G switch silicon.
Standards and Compatibility
On the compatibility side, this unit is the practical equivalent of the Cisco part QSFP-100/112G-ER4 and works in Cisco systems out of the box. Standards compliance covers 100G Ethernet, 100G Telecom Connections.
Ordering Information
Order this product as QSFP-ER4-100GM. 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.
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.
Tested Before Shipment
We do not ship untested stock. Each transceiver and cable is powered up in our test racks, checked for link stability, transmit power, receiver sensitivity and diagnostic readouts, and only then packed for delivery. This factory-level testing is one reason network integrators keep reordering from us year after year.
Packaging
Each unit is sealed in an anti-static bag, cushioned in a blister tray and boxed in an export-grade carton. Outer cartons carry handling marks and can be palletized for air or sea freight. If your project requires retail boxes, barcodes or your own brand on the label, we can arrange that as well.
