In data center interconnect, metro transport and carrier aggregation networks, the 100G QSFP28 ZR4 4x 25G NRZ QSFP-100G-ZR4-S 1310nm 80km Duplex LC/UPC Module, Cisco delivers 103.125Gbps (4x 25.78Gbps) transmission over SMF with a reach of 80km. 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-ZR4-S directly. The link runs 4x 25G-NRZ modulation, which keeps it aligned with current 100G switch silicon.
Compliance: QSFP28 MSA, SFF-8636, IEEE 802.3bm, CAUI-4. For projects standardized on Cisco hardware, this product replaces the QSFP-100G-ZR4-S 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.
Our part number for this module is QSFP-ZR4-100G. 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.
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.
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.
Working directly with the manufacturer means no middleman limits. We support OEM and ODM projects, custom cable assemblies, alternative packaging and compatibility coding for major equipment vendors, with engineering support from the same team that designs our standard products.
Standard products are held in stock and usually ship within one to three working days. We dispatch worldwide by DHL, UPS, FedEx, TNT or EMS, and for bulk orders we arrange air or sea freight. Shipments can also be sent collect on your own courier account or delivered to your freight forwarder.
