Applications
In 100G Ethernet, data center interconnect and 5G transport networks, the 100G QSFP28 PSM4 4x 25G NRZ QSFP-100G-PSM4-S 1310nm 500m MPO-12/APC Module, Cisco delivers 103.125Gbps (4x 25.78Gbps) transmission over SMF with a reach of 500m@OS2. Digital diagnostics report transmit power, receive power and temperature in real time, which simplifies commissioning and ongoing maintenance. It is interoperable with Cisco platforms and replaces the Cisco part QSFP-100G-PSM4-S directly. 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-100G-PSM4-S and works in Cisco systems out of the box. Standards compliance covers QSFP28 MSA, SFF-8636, IEEE 802.3‑2012, CAUI-4.
Ordering Information
Order this product as QSFP-PSM4-100G-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.
Delivery
Goods are normally sent by courier such as DHL, UPS, FedEx, TNT or EMS; air and sea freight are also available on request. Commonly used items are kept in stock for immediate shipment, and out-of-stock items are usually delivered within a few working days. We can also ship on your courier account or hand goods to your appointed forwarder.
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 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.
Custom-made Fiber Products
As a manufacturer serving the fiber optic industry since 1995, we have strong in-house manufacturing and design capability. From early GBIC, Xenpak and X2 modules to today's SFP, SFP+, QSFP, QSFP-DD and OSFP products, we grow together with the industry. OEM and custom-designed transceivers and cables are welcome, and our factory-direct pricing is very competitive compared with online retail stores.
