Optický transceiver modul BlueOptics ET7402-CWDM4-BO QSFP28 LC

The BlueOptics ET7402-CWDM4-BO QSFP28 LC is a fiber optic transceiver module designed for high-speed 100G data transmission over single-mode fiber. Housed in an aluminium enclosure and weighing approximately 40 g, the module uses a QSFP28 interface with an LC duplex connector and follows MSA-compatible form factor standards. It supports CWDM4 wavelength multiplexing to transmit and receive optical signals concurrently, enabling reliable connectivity for data centers and high-performance network equipment.

Advantages

This module provides compatibility with hardware platforms that support the 100GBASE-CWDM4 QSFP28 standard and is produced according to common MSA specifications. The use of CWDM4 technology allows four wavelength channels to be carried over single-mode fiber, providing a compact high-bandwidth solution. The aluminium housing offers physical durability while the QSFP28 form factor supports high-density port deployment in switches and routers. The module is suitable for Ethernet and other high-speed protocols up to 100 Gbit/s across short to medium single-mode fiber links.

How to use

Install the QSFP28 transceiver into a compatible QSFP28 port on a switch, router or compatible network device following the device manufacturer’s handling instructions. Connect LC duplex single-mode fiber patch cords to the module’s LC connector, ensuring correct TX/RX orientation. Configure the host device for 100G operation and, if required, verify link parameters and firmware compatibility with the system BIOS or operating software. Observe electrostatic discharge precautions during handling and avoid mechanical stress on the connector and fiber.

Recommendations

For optimal performance, use high-quality single-mode LC patch cords and route fibers via appropriate panels or management to minimize bend radius and signal loss. Confirm device compatibility and test the transceiver in a controlled environment before large-scale deployment. Regularly inspect connectors for contamination and clean with approved fiber cleaning tools when necessary.
