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
Our part number for this module is QSFP-ZRHF-100G-S. 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.
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.
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.
OEM and Custom Orders
We have manufactured fiber optic connectivity products since 1995 and run our own production lines in Shenzhen. Beyond the standard catalog we build to order: special cable lengths, custom connector combinations, vendor-specific compatibility coding and private labeling. Send us your requirement and our engineers will quote a practical solution.
