The Cisco 100GBASE QSFP (Quad Small Form-Factor Pluggable) modules provide high-density, low-power 100 Gigabit Ethernet connectivity options suitable for data centers, high-performance computing networks, enterprise core and distribution layers, and service provider applications. These modules are based on the QSFP form factor and include various types such as SR4, LR4, CWDM4, PSM4, and active optical cables with different reach capabilities and connector types.
Key features and types include:
- 100GBASE SR4 QSFP: Supports 100 meters over OM4 multimode fiber with MPO connectors.
- 100GBASE LR4 QSFP: Supports 10 km over single-mode fiber with LC connectors.
- 100GBASE CWDM4 QSFP: Supports 2 km over single-mode fiber.
- 100GBASE PSM4 QSFP: Supports 500 meters over single-mode fiber.
- Active Optical Cables (AOC): Available in lengths from 1 meter up to 30 meters.
- Passive Copper Cables (CR4): Available in lengths from 1 meter to 3 meters.
Additionally, the Cisco QSFP-100G-ZR4-S module provides 100G ZR connectivity with a reach of up to 80 km over single-mode fiber, using duplex LC connectors and requiring host-based RS-FEC (Reed Solomon Forward Error Correction).
These modules are hot-swappable, interoperable with IEEE-compliant interfaces, certified on Cisco platforms, and compliant with IEEE 802.3 standards. They support various optical connectors and power consumption levels depending on the model.
