## Summary description

The BlueOptics Q28-100G-ER4-LITE-BO is a fiber optic QSFP28 transceiver module designed for high-speed data transmission. It features CWDM technology and is lightweight at 40g. Ideal for network applications requiring efficient and reliable connectivity.

## Long description

The BlueOptics Q28-100G-ER4-LITE-BO QSFP28 CWDM is a compact fiber optic transceiver module for 100G high-speed links over single-mode fiber. Designed to meet MSA QSFP28 form-factor expectations, it provides CWDM-based transmit and receive channels in an LC duplex interface, enabling 100GBASE-ER4 Lite connectivity over distances up to 30 km. The module weighs approximately 40 g and has an aluminium housing suitable for integration into compatible network equipment that supports QSFP28 optical interfaces.
Advantages
This transceiver delivers 100 Gbit/s optical throughput using CWDM channels, reducing the number of required fibers while maintaining separate transmit and receive paths via an LC duplex connector. It supports digital diagnostics monitoring (DDM/DOM) to report supply voltage, laser bias current, transmit power, received power and temperature for remote troubleshooting. The module is manufactured to MSA-aligned specifications and is compatible with major platforms that accept equivalent QSFP28 100GBASE-ER4 Lite optics, offering a stable solution for long-reach single-mode connections.
Suitable for
Long-reach 100G Ethernet links over single-mode fiber up to 30 km
Core and aggregation switches with QSFP28 uplinks
High-speed interconnects between data center racks and buildings
Fibre Channel over Ethernet and SDH/SONET high-speed applications
Key specifications
Form factor: QSFP28
Data rate: 100 Gbit/s (100GBASE-ER4 Lite)
Optical technology: CWDM transmitter and receiver
Connector: LC duplex
Fiber type: Single-mode fiber
Maximum reach: up to 30 km (single-mode)
Housing colour/material: aluminium
Weight: approximately 0.04 kg
Monitoring: Digital Diagnostics Monitoring (DDM/DOM) compliant with MSA standards
How to use
Install the QSFP28 transceiver into a compatible QSFP28 slot on the switch, router or other network device while the host device is powered off or following the vendor’s hot‑swap instructions. Connect an LC duplex single‑mode patch cord to the transceiver and to the remote transceiver or patch panel. Verify link status and lane alignment through the host device management interface. If supported by the hardware and software, use the DDM/DOM telemetry to monitor module parameters for diagnostics and preventive maintenance.
Usage recommendations
Ensure the host equipment explicitly supports 100GBASE-ER4 Lite QSFP28 optics and that firmware or driver settings do not block third‑party transceivers. Use quality single‑mode LC patch cords and follow standard fiber handling practices: keep connectors clean, avoid tight bends, and secure cables to prevent strain. Monitor DDM values during commissioning and periodically in production to detect deviations in power or temperature that may indicate connection or component issues.
