Fiber optic transceiver module BlueOptics QTA1C04L2E000E1A-BO 100000 Mbit/s QSFP28

The BlueOptics QTA1C04L2E000E1A-BO QSFP28 fiber optic transceiver module supports data rates up to 100000 Mbit/s and is designed for single-mode fiber links. Housed in a durable silver metal casing and weighing approximately 40 g, this module follows MSA QSFP28 form-factor conventions and provides LC duplex optical connectivity for long-reach 100GBASE-LR4 applications. It is intended for use in networking equipment that accepts QSFP28 modules and supports high-speed Ethernet, Fibre Channel over Ethernet or SDH/SONET protocols over distances up to 10 km when deployed on appropriate single-mode fiber.

Advantages

The module offers a compact QSFP28 footprint that enables high-density port deployment and maintains compatibility with MSA-compliant QSFP28 ports. Its metal housing provides mechanical robustness and thermal conduction for stable operation. The transceiver implements CWDM-based transmitter and receiver optics suitable for long-reach single-mode links and includes support for digital diagnostics (DDM/DOM) to report realtime parameters such as supply voltage, laser bias current, optical output and input power, and temperature. Low weight and standardized form factor simplify installation and replacement in racks, switches, routers and storage systems.

How to use

Install the QSFP28 module into a compatible QSFP28 port following the host equipment manufacturer’s hot-swap guidelines. Connect LC duplex single-mode fiber patch cords to the module’s LC ports, ensuring correct transmit/receive orientation and using appropriate fiber patch panels or adapters if required. Verify link status and optical parameters through the host system’s management interface; if supported, use the DDM/DOM readings for realtime diagnostics. Observe electrostatic discharge precautions when handling the transceiver and keep optical connectors capped when not in use to prevent contamination.

Usage recommendations

Use single-mode LC duplex fiber rated for 100G applications and confirm the host hardware supports 100GBASE-LR4 QSFP28 modules and DDM/DOM functionality. Clean connectors before mating and verify link power budget for distances near the maximum range. For high-density deployments, monitor module temperatures and airflow to maintain reliable operation.
