Glasvezel-transceivermodule BlueOptics Q28-100G-CWDM4 100000 Mbit/s QSFP28

The BlueOptics Q28-100G-CWDM4 is a fiber optic transceiver module designed for high-speed data transmission over single-mode fiber. Featuring a QSFP28 interface and a maximum data transfer rate of 100000 Mbit/s, this module fits into 100 Gigabit Ethernet deployments and other high-bandwidth networking environments. The compact QSFP28 form factor supports dense port counts in switches and servers while enabling hot-pluggable upgrades without system downtime.

Advantages

The module provides a standardized QSFP28 connection that simplifies integration into existing 100 GbE infrastructures. Its support for coarse wavelength division multiplexing (CWDM4) enables efficient use of fiber links by carrying multiple wavelengths over a single fiber pair, reducing cabling complexity. With a 100000 Mbit/s throughput, the transceiver addresses the needs of data center uplinks, switch-to-switch links and aggregation layers requiring predictable, high-capacity links.

Suitable for

• 100 Gigabit Ethernet uplinks in data centers and campus networks
• High-capacity switch-to-switch and server-to-switch connections
• Fiber backbone and aggregation links that require CWDM4 wavelength multiplexing
• Network environments that use QSFP28 ports for compact, high-density installations

Key specifications

• Interface type: QSFP28
• Maximum data transfer rate: 100000 Mbit/s (100 Gb/s)
• Optical technology: CWDM4 (coarse wavelength division multiplexing)
• Form factor: QSFP28 hot-pluggable module

How to use

Install the transceiver into a compatible QSFP28 slot on a switch, router or server according to the host equipment instructions. Connect appropriate single-mode fiber cables and, if required, CWDM-compatible patching to match wavelength assignment. Verify link status and speed through the network device management interface and follow any vendor-specific steps for enabling 100 GbE ports. For safe handling, avoid touching fiber faces and follow electrostatic discharge (ESD) precautions when inserting or removing the module.

Recommendations

Use single-mode fiber and CWDM-capable cabling infrastructure for best performance. Confirm compatibility with the host device documentation and, when replacing or upgrading transceivers, match optical parameters and connector types to preserve link integrity. Schedule maintenance windows for any in-line upgrades to prevent unintended service interruptions.
