DP01QS28-E20 — QSFP28 100 Gbps

The DP01QS28-E20 is a Cisco QSFP28 100 Gbps module compliant with the IEEE 100GBASE-ZR and ITU-T G.709.2 standards, enabling coherent links up to 300 km over single-mode fiber with an LC (UPC) connector. Its thermal operating range of +15 to +70 °C is optimized for climate-controlled datacenter environments. This optical transport transceiver is intended for long-distance infrastructure on OTN networks.

The DP01QS28-E20 is suited to operators and ISPs deploying coherent 100G links over very long distances in server rooms or datacenters with thermal control, where temperatures remain within the 15 to 70 °C range. Compared to the DP01QS28-E25, its narrower thermal profile restricts it exclusively to controlled indoor environments, while offering the same 300 km reach.
