Cisco 100GBase-FR Transceiver Module | QSFP-100G-FR-S | Cisco Transceiver Module | New The Cisco QSFP‑100G‑FR‑S is a 100GBASE‑FR1 optical transceiver module tailored for 2 km single-mode fiber (SMF) links, using a single-wavelength (1310 nm) connection via duplex LC connectors. It supports 100 Gigabit Ethernet through PAM4 modulation and integrates host-based Forward Error Correction (FEC) for reliable data transmission. Features: Form Factor: QSFP28 (Quad Small Form-Factor Pluggable). Data Rate: Supports up to 103.125 Gbps (commonly marketed as 100G). Wavelength: 1310 nm (single-lambda), with TX power typically ranging from –3.1 to +4 dBm. Modulation: PAM4, enabling efficient higher data density on one wavelength. FEC: Host-based forward error correction (RS‑FEC per IEEE 802.3cd). Digital Diagnostics (DOM): Supported for real-time monitoring of operational parameters. 100G Lambda MSA and QSFP28 MSA Power Consumption: Typically ≤ 4.3 W, with some references stating ≤ 4.5 W max. Applications: High-speed data center interconnects Enterprise core and distribution networks Telecom backbones and medium-range 100G Ethernet links
