ODN and passive infrastructure knowledge brief Published 26 Apr 2023

Prepared for preliminary research by the GESTIONVAL ODN knowledge desk. Confirm network topology, split ratio, box or cabinet capacity, joint closure rating and loss budget against current standards and product documentation.

Cisco offers a wide range of optical modules, including SFP, SFP+, SFP28, QSFP+, QSFP28, QSFP-DD, OSFP, CWDM, and DWDM modules.

Cisco optical modules are pluggable transceivers used in switches, routers, and servers to transmit data over fiber optic cables. They vary by form factor, speed, and transmission distance, supporting network speeds from 1 Gbps to 400 Gbps . The main categories include:

  • SFP (Small Form-Factor Pluggable): Supports 1 Gbps, suitable for short to medium distances .
  • SFP+: Enhanced SFP for 10 Gbps networks .
  • SFP28: Supports 25 Gbps, commonly used in modern data centers .
  • QSFP+: Aggregates four 10 Gbps channels for 40 Gbps total .
  • QSFP28: Supports 100 Gbps, widely used in high-performance networks .
  • QSFP-DD / OSFP: High-density modules supporting 400 Gbps for advanced data center deployments .
  • CWDM and DWDM modules: Coarse and dense wavelength division multiplexing modules for long-haul optical networks . Each module type can further vary by fiber type (single-mode or multimode), wavelength, and transmission distance, allowing Cisco to provide solutions for intra-rack, campus, and long-haul network applications . While the exact number of individual models is extensive and continuously updated, Cisco maintains a comprehensive list of transceiver models on their official datasheets . In summary, Cisco optical modules cover a broad spectrum of speeds and applications, from 1 Gbps SFPs to 400 Gbps QSFP-DD/OSFP modules, ensuring compatibility with a wide range of networking equipment and deployment scenarios.
