## Summary description

Compact BlueOptics QSFP28 transceiver (EQPT1H4ER4ECL1LT-BO) supporting 100GBASE-ER4L for long-reach 100 GbE links. Uses LC-duplex connectors over singlemode fiber at 1310 nm, with a reach of up to 30 km. Supports digital diagnostics monitoring (DDM) and operates in an industrial temperature range of 0°C to +70°C. Suitable for data center uplinks and metro transport.

## Long description

BlueOptics QSFP28 Transceiver EQPT1H4ER4ECL1LT-BO is a compact optical module designed for long-reach 100 Gigabit Ethernet links. It supports the 100GBASE-ER4L standard over singlemode fiber using LC-duplex connectors and operates at a wavelength of 1310 nm. The module delivers a reach of up to 30 km and includes Digital Diagnostics Monitoring (DDM) to report real-time operational parameters. The transceiver is specified to function across an industrial temperature range from 0 °C to +70 °C, making it suitable for data centre uplinks and metro transport applications.
Advantages
The BlueOptics QSFP28 provides a dense, high-speed interface for 100 GbE links while retaining a small QSFP28 form factor, enabling efficient port density in switches and routers. Its LC-duplex connectors and singlemode operation at 1310 nm allow compatibility with standard long-haul singlemode fiber plants. Built-in DDM offers visibility into key parameters such as temperature, optical power, and supply voltage, aiding troubleshooting and monitoring. The industrial operating range improves reliability in environments with elevated ambient temperatures.
Suitable for
Data centre uplinks and spine-to-leaf interconnects requiring 100 GbE long-reach links
Metro aggregation and long-distance campus links up to 30 km
Network equipment that supports QSFP28 modules and LC-duplex singlemode interfaces
Environments that require basic transceiver monitoring via DDM
When it may not be suitable
This transceiver is designed specifically for singlemode fiber and LC-duplex interfaces at 1310 nm; it is not suitable for multimode fiber systems or for networks that require different wavelengths such as 850 nm. It also targets long-reach 100GBASE-ER4L links — for short-reach or active electrical breakout use cases, other QSFP28 variants (e.g., SR or DAC) would be more appropriate.
Key specifications
Format: QSFP28 optical transceiver
Data rate: 100 Gigabit Ethernet (100GBASE-ER4L)
Fiber type: Singlemode fiber
Wavelength: 1310 nm
Connector: LC-duplex
Maximum reach: up to 30 km
Monitoring: Digital Diagnostics Monitoring (DDM)
Operating temperature range: 0 °C to +70 °C
How to use
Insert the QSFP28 transceiver into a compatible QSFP28 port on a switch, router or transponder, making sure the module is oriented correctly and the connector latches engage. Connect LC-duplex singlemode fiber patch cables to the TX/RX pairs, follow proper fibre handling to avoid contamination or bend losses, and verify link status on the host device. Use the host management interface or monitoring tools to read DDM parameters for real-time diagnostics such as optical power and module temperature.
What to consider before purchase
Ensure the host device supports QSFP28 form factor and the 100GBASE-ER4L standard
Verify the existing fiber plant uses singlemode fiber with LC connectors and can support 30 km reach
Confirm the required operating temperature range fits the intended deployment environment
Check compatibility policies of your network equipment vendor regarding third-party transceivers
Usage recommendations
Maintain clean LC connectors, avoid tight fiber bends, and validate link parameters after installation. Use monitoring of DDM values to detect degradation in optical power or temperature changes early. For distances shorter than the supported 30 km, ensure power budget and dispersion remain within acceptable margins for reliable operation.
