- Hot-Swappable: The modules are hot-pluggable, meaning you can install or replace them without powering down the switch or router .
- Digital Optical Monitoring (DOM): Many Cisco MMF SFP models, such as the GLC-SX-MMD, support DOM. This feature allows you to monitor real-time parameters like optical output power, input power, temperature, and supply voltage for proactive diagnostics .
- Cisco Quality ID: A built-in identification feature enables the Cisco platform to verify that the module is certified and tested by Cisco, ensuring compatibility and reliability .
- Standard Connector: Cisco multimode SFPs typically use a Dual LC/PC connector for the fiber connection .
Common Specifications (Example: 1000BASE-SX)
The most common Cisco MMF SFP for Gigabit Ethernet is the
1000BASE-SX standard (e.g., part number
GLC-SX-MMD). Its key specifications are:
- Wavelength: 850 nm .
- Fiber Type: Multimode Fiber (MMF) .
- Max Distance: Varies by fiber grade, typically:
- 550 m over 50μm MMF (OM2/OM3) .
- 220-275 m over 62.5μm MMF (OM1) .
- Data Rate: 1.25 Gbps (Gigabit Ethernet)
