CBO transceptor QSFP28 QSFP28-100G-CWDM4-PA-BO — módulo de fibra óptica 100G CWDM4

The BlueOptics CBO QSFP28 Transceiver QSFP28-100G-CWDM4-PA-BO is a hot-pluggable 100G CWDM4 fiber optic module designed for high-density 100 Gigabit Ethernet links. It complies with the QSFP28 form factor compatible with Palo Alto Networks QSFP28-100G-CWDM4 ports and uses coarse wavelength division multiplexing (CWDM4) over single-mode fiber to deliver reliable 100G connectivity across extended distances. The module is intended for data center and enterprise network environments where simplified fiber management and long-reach 100G links are required.

Advantages

This CWDM4 transceiver offers a compact QSFP28 form factor that supports hot-plug installation and straightforward integration into existing 100G infrastructures. By using CWDM4 technology over single-mode fiber, it reduces fiber count compared with parallel optics solutions while maintaining 100G throughput. The module is suitable for dense deployments, enabling efficient use of rack and switch ports and supporting simplified cable management in high-density racks.

Suitable for

• 100 Gigabit Ethernet uplinks between switches and core routers
• Long-distance 100G connections within data centers and between campus sites
• High-density port installations in aggregation and spine-leaf network architectures
• Network upgrades from 10G/40G to 100G where single-mode fiber is available

Key specifications

• Form factor: QSFP28 (hot-pluggable)
• Data rate: 100 Gbps
• Optical technology: CWDM4 (coarse wavelength division multiplexing)
• Fiber type: single-mode fiber
• Typical reach: designed for extended distance 100G links (CWDM4 range over SMF)
• Application: 100 Gigabit Ethernet
• Compatibility: QSFP28 ports compatible with Palo Alto Networks QSFP28-100G-CWDM4 form factor

How to use

Install the transceiver into a compatible QSFP28 port on a switch, router or network appliance while the device is powered on; the hot-pluggable design permits insertion and removal without powering down the host. Connect appropriate single-mode fiber cables with CWDM4-compatible passive MUX/DEMUX or duplex LC connections as required by the network design. Verify link status and interface configuration on the host device to ensure the 100G link is negotiated and operating at the expected speed.

Recommendations

Use certified single-mode fiber and ensure proper cleaning of fiber connectors before installation to maintain signal integrity. Match the module form factor and optical type to the host port and network architecture, and verify transceiver compatibility with vendor switch firmware when integrating into existing environments.
