Questions & Answers
What is a Cisco 25G optical module?
A Cisco 25G optical module is a pluggable transceiver designed for 25 Gigabit Ethernet applications, converting electrical signals to optical signals for high-speed data transmission.
Which form factors are available for Cisco 25G optical modules?
Cisco 25G optical modules are available in SFP28 form factor for single-lane links and QSFP28 breakout modules supporting four 25G lanes from a single port.
What types of Cisco 25G optical modules does Cisco offer?
Cisco offers 25G SR (Short Reach), LR (Long Reach), and PSM4 modules, each supporting different distances over multimode or single-mode fiber.
What is the maximum transmission distance for Cisco 25G SR modules?
Cisco 25G SR modules support up to 100 meters over OM3 multimode fiber and up to 70 meters over OM4 fiber at 850 nm wavelength.
How far can Cisco 25G LR modules transmit data?
Cisco 25G LR modules support distances up to 10 kilometers over single-mode fiber at 1310 nm wavelength.
Which Cisco switches support 25G optical modules?
Cisco 25G optical modules are supported on Nexus 9000, Nexus 3000, Catalyst 9500, Catalyst 9300, and UCS Fabric Interconnect series.
Are Cisco 25G optical modules compatible with third-party optics?
Cisco 25G optical modules are Cisco-tested and validated; third-party optics may work but are not covered under Cisco warranties or support agreements.
How do I install a Cisco 25G optical module?
To install, align the module with the switch port, gently insert until it clicks, then attach the LC or MPO patch cable according to the module type.
How can I verify my Cisco 25G optical module is operational?
Use the ‘show interface transceiver details’ CLI command to check module status, temperature, voltage, and receive/transmit power levels.
What is the typical power consumption of a Cisco 25G SFP28 module?
Cisco 25G SFP28 modules consume approximately 1.2 to 1.5 watts under normal operating conditions per port.
What wavelength do Cisco 25G optical modules use?
Cisco 25G SR modules operate at 850 nm and LR/ER modules at 1310 nm, while PSM4 uses multiple 1310 nm lanes in a MPO connector.
What is the difference between 25G SR and 25G LR modules?
25G SR modules are multimode optics for short distances (up to 100 m), while 25G LR modules are single-mode optics for distances up to 10 km.
Can I use Cisco 25G direct attach cables instead of optical modules?
Direct attach cables (DAC) provide low-cost, short-reach connectivity up to 10 m, whereas optical modules with fiber support longer distances and flexible upgrades.
How do I troubleshoot link issues with Cisco 25G modules?
Check transceiver diagnostics with ‘show interface transceiver’, verify fiber cleanliness, replace faulty cables, and confirm switch port configuration.
How do I update the firmware on Cisco 25G optical modules?
Cisco 25G modules are typically firmware-free; module behavior is coordinated via the switch IOS or NX-OS software which you update through standard image upgrade procedures.
What warranty and support options are available for Cisco 25G modules?
Cisco 25G optical modules come with a one-year limited hardware warranty; extended support is available through Cisco SMARTnet or Cisco Solution Support contracts.
