10ge optical module parameters

10GE SFP+ optical modules support a range of fiber types, wavelengths, and link distances, with hot-swappable SFP+ form factors and digital diagnostic monitoring capabilities.

Form Factor and Compatibility

10GE optical modules typically use the SFP+ form factor, which is the industry's smallest 10G module, allowing high port density in switches and routers. They are hot-swappable, meaning they can be installed or replaced without powering down the device, and are compatible with multiple 10G standards including XENPAK, X2, and XFP interfaces on the same link (Cisco) . Modules are compliant with SFP+ MSA and IEEE 802.3 10GBASE standards .

Fiber Types and Wavelengths

• Multimode Fiber (MMF): Commonly used for short-range links.
  • 10GBASE-SR: 850 nm, up to 300 m on OM3, 400 m on OM4 .
  • 10GBASE-LRM: 1310 nm, up to 220 m on OM3 .
• Single-Mode Fiber (SMF): Used for longer distances.
  • 10GBASE-LR: 1310 nm, up to 10 km .
  • 10GBASE-ER: 1550 nm, up to 40 km (practical distances may vary, e.g., 20 km for some modules) .
  • 10GBASE-ZR: 1550 nm, up to 80 km .
• Bidirectional (BIDI) Modules: Single-fiber modules must be paired with complementary wavelengths, e.g., 1270 nm/1330 nm .
• CWDM/DWDM Modules: Support multiple wavelengths for dense wavelength-division multiplexing, with distances from 10 km to 100 km depending on the module .

Connector Types

• LC Duplex: Standard for most fiber SFP+ modules.
• RJ-45: Used for 10GBASE-T copper modules, supporting distances up to 30–100 m over Cat6a/Cat7 cables .
• Simplex LC: Used for BIDI modules .

Data Rates and Protocols

• Supports 10 Gbps Ethernet, with some modules capable of dual-rate operation for 1G/10G compatibility.
• Can also support other protocols with bitrates from 600 Mbps to 11.1 Gbps .

Digital Diagnostics and Monitoring

Most 10GE SFP+ modules include Digital Optical Monitoring (DOM/DDM), providing real-time monitoring of parameters such as optical output power, input power, temperature, voltage, and laser bias current .

Environmental and Compliance

• Modules are Class 1 laser products, compliant with IEC-60825 and FDA 21 CFR 1040.10/1040.11 .
• Operating temperature ranges vary; some modules support industrial temperature ranges for extended deployment environments .
