Questions & Answers

What is a Cisco 100G Optical Module?

Cisco 100G Optical Modules are hot-pluggable transceivers supporting up to 100 Gbps to enable high-speed fiber connectivity in Cisco switches and routers.

What form factors do Cisco 100G Optical Modules come in?

Cisco offers 100G modules in QSFP28 and CFP2/CFP4 form factors to fit various platform densities and power requirements.

What transmission distances are supported by Cisco 100G Optical Modules?

Cisco 100G SR modules support up to 100 meters on multimode fiber, LR up to 10 kilometers, ER up to 40 kilometers, and ZR up to 80 kilometers on single-mode fiber.

Are Cisco 100G Optical Modules interoperable with third-party transceivers?

Cisco 100G modules are designed for full interoperability with Cisco hardware, but compatibility with third-party optics can vary and is not guaranteed by Cisco.

How do I choose between Cisco 100G SR, LR, ER, and ZR modules?

Select SR for short-range multimode links, LR for up to 10 km single-mode, ER for up to 40 km, and ZR for up to 80 km, based on your required distance and fiber type.

What fiber types are compatible with Cisco 100G Optical Modules?

Cisco 100G SR modules support OM3/OM4 multimode fiber, while LR, ER, and ZR modules require single-mode OS1/OS2 fiber.

Do Cisco 100G Optical Modules support digital diagnostics monitoring (DDM)?

Yes, all Cisco 100G Optical Modules include digital diagnostics to monitor real-time power, temperature, and signal integrity.

Can Cisco 100G Optical Modules be hot-swapped?

Yes, Cisco 100G Optical Modules are hot-swappable and can be inserted or removed without powering down the system.

What wavelength specifications do Cisco 100G Optical Modules use?

Cisco 100G SR modules operate at 850 nm, LR modules at 1310 nm, ER at 1550 nm, and ZR optionally deploy DWDM wavelengths around 1550 nm.

How do I verify compatibility of Cisco 100G Optical Modules with my switch?

Check Cisco’s hardware compatibility matrix or consult the data sheet for your switch model to confirm supported module types and software versions.

What is the typical power consumption of Cisco 100G Optical Modules?

Power consumption varies by type: SR modules draw around 3.5 W, LR around 4.5 W, ER around 6.5 W, and ZR around 8.5 W.

Are Cisco 100G Optical Modules covered under Cisco’s warranty?

Yes, Cisco 100G Optical Modules are covered by Cisco’s standard one-year hardware warranty, with options to extend support via Cisco SMARTnet.

How do I install a Cisco 100G Optical Module?

Align the module’s handle with the port, gently slide it in until it clicks, then secure the fiber connectors, following Cisco’s installation guide.

What environmental operating conditions do Cisco 100G Optical Modules require?

Cisco 100G modules operate between 0 °C and 70 °C, with relative humidity from 5% to 85%, non-condensing.

How can I identify the correct Cisco part number for a 100G Optical Module?

Reference Cisco’s product catalog or data sheet which lists part numbers by form factor, distance (SR, LR, ER, ZR), and fiber type.
