QSFP transceiver BlueOptics QSFP-100G-CWDM4-AL-BO 100000 Mbit/s QSFP28

The BlueOptics QSFP-100G-CWDM4-AL-BO is a 100G QSFP28 fiber optic transceiver designed for high-speed single-mode connections. Housed in a durable metal casing and weighing only 4 g, the module supports a maximum data transfer rate of 100000 Mbit/s and operates from a 3.3 V supply. The transceiver implements CWDM4 wavelength multiplexing with an LC duplex optical interface and complies with MSA QSFP28 mechanical and electrical specifications for broad interoperability with compatible network hardware.

Advantages

This QSFP28 transceiver offers high-density 100G performance in a compact form factor, enabling efficient port consolidation in switches, routers and storage systems. Built to MSA standards and using quality optical components, the module provides consistent optical performance, digital diagnostics monitoring for remote status information, and low weight for easy handling and installation.

Suitable for

• 100G Ethernet links over single-mode fiber

How to use

Insert the QSFP-100G-CWDM4-AL-BO module into a compatible QSFP28 cage on the target device following the vendor's hot-plug procedures. Connect LC duplex single-mode fiber patch cords to the module's optical ports, ensuring correct polarity. Verify that the host hardware and firmware support 100GBASE-CWDM4 modules and enable DDM/DOM if diagnostic readout is required. After installation, check link LEDs or the management interface to confirm an active 100G link and monitor optical parameters through the device's diagnostic tools.

Recommendations

Use high-quality single-mode LC patch cords and maintain clean connectors to ensure optimal signal quality. Confirm compatibility with the specific switch or router model and its firmware version before deployment. When planning links, account for the module's 2 km typical reach and ensure fiber attenuation and connector loss remain within margin for reliable operation.
