Applications
Network architects choose the 100G QSFP28 ZRHF DCO ≤120km DWDM C-band Tunable Digital Coherent Module, Cisco for data center interconnect, metro transport and carrier aggregation networks: it runs 100Gbps over Duplex SMF and reaches unamplified: ≤120kmamplified: ≤300km. The Duplex LC/UPC interface and 100GHz gird: 1528.77~1566.31nm50GHz gird: 1528.77~1566.72nm optics match the standard cabling plant used in modern data halls, so existing trunks can be reused. If your project needs a specific vendor coding or custom label, our production line handles it as a routine step before packing. The link runs 4x 25G NRZ, DP-DQPSK modulation, which keeps it aligned with current 100G switch silicon.
Standards and Compatibility
Standards compliance covers IEEE 802.3™-2022, 100GBASE-ZR, CMIS, SFF-8024. The unit works in any equipment with a standard QSFP28 interface; if your network uses a specific vendor's coding, tell us the switch model and we will program and verify it before delivery.
Ordering Information
To order, quote QSFP-ZRHF-100G-S 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.
Built to Your Spec
Our product line has grown with the industry for three decades, from GBIC-era modules to today's 800G and 1.6T interconnects. If the exact configuration you need is not listed, we can usually build it: custom lengths, mixed connector breakouts, OEM branding and project-specific firmware coding are all supported.
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.
Quality Assurance
Before any product leaves our factory it goes through optical performance testing, compatibility verification on real switch platforms and a final visual inspection. Our in-house test lab holds a wide range of current and legacy switches from major brands, so interoperability is proven on the actual equipment your network uses rather than assumed from paper specifications.
Package
Products are first packed into blister trays or self-sealed bags and then into cartons. Standard labels and marks are applied by default, and customized packing and labeling are available on request.
