Zyxel SFP25G-SR-ZZ0101F network transceiver module Fiber optic 25000 Mbit/s SFP28 850 nm

Zyxel SFP25G-LR-ZZ0101F is a compact SFP28 25 Gigabit optical transceiver designed for short-range links. Operating at an 885 nm wavelength, this module delivers 25G serial optical connectivity in the SFP28 form factor for high-speed uplinks and data center interconnects. It is intended for short multimode or other specified short-range fiber runs where a small, hot-pluggable 25G solution is required to upgrade switches, routers or servers.

Advantages

The transceiver combines a small SFP28 footprint with 25 Gigabit data rate capability and an 885 nm optical interface optimized for short-reach connections. Its hot-pluggable design simplifies field installation and replacement without powering down equipment. The module is suitable for dense deployment in racks and chassis due to the compact form factor, and it supports typical operating ranges and power parameters for short-range multimode links.

Suitable for

• 25G uplinks between switches in top-of-rack and spine-leaf architectures
• Data center server to switch connections requiring 25G bandwidth
• Short-range multimode fiber interconnects inside racks or between adjacent cabinets
• Network upgrades where SFP28 ports are available and higher throughput is needed

Key specifications

• Form factor: SFP28 (hot-pluggable)
• Nominal data rate: 25 Gigabit per second (serial)
• Wavelength: 885 nm
• Link type: short-range multimode fiber or specified short-range optical runs
• Typical use: uplinks and data center interconnects

How to use

Insert the SFP28 transceiver into a compatible SFP28 port on a switch, router or server while equipment is powered on, taking care to align the module and fully seat it in the cage. Connect the appropriate multimode fiber patch cord with matching connector type and ensure proper polarity. Verify link status through the host device management interface and monitor signal and interface statistics to confirm stable operation. Replace the module by removing it from the port and inserting a new unit as needed.

Recommendations

Use factory-tested multimode fiber and appropriate patch cords rated for short-range 25G operation. Confirm compatibility with the host device vendor and firmware releases where required. Avoid extended temperature or mechanical stress outside specified operating conditions and observe electrostatic discharge precautions during handling and installation.
