## Summary description

BlueOptics QSFP28 100GBASE-ER4 transceiver module for singlemode fiber with LC-Duplex connector. Uses internal 4‑wavelength WDM (4×1296–1309 nm) to deliver 100 Gbps over up to 40 km. Supports DDM/DOM for diagnostic monitoring and operates in the 0–70°C range. Designed for long-reach data center and carrier links requiring QSFP28 100G connectivity.

## Long description

BlueOptics QSFP28 100GBASE-ER4 Singlemode LC-Duplex transceiver is a pluggable 100 Gbps module designed for long-reach optical links over singlemode fiber. The module integrates four WDM transmit wavelengths (4×1296–1309 nm) and a single LC-Duplex connector to deliver aggregated 100 Gbps throughput across distances up to 40 km. It supports Digital Diagnostic Monitoring (DDM/DOM) and is specified to operate in environments with ambient temperatures from 0 to 70°C, making it suitable for data center uplinks and carrier-grade point-to-point connections that require QSFP28 form factor 100G connectivity.
Advantages
The transceiver offers long-reach capability up to 40 km on singlemode fiber using internal 4‑wavelength WDM, reducing fiber pair requirements while maintaining full 100 Gbps throughput. Built-in DDM provides real-time monitoring of optical parameters such as transmit and receive power, temperature, and supply voltage. The QSFP28 form factor ensures high-density deployment in modern switches and routers, while the LC-Duplex interface provides compatibility with standard singlemode cabling. The module’s operating temperature range and standardized electrical and optical behaviour support reliable operation in typical rack and carrier environments.
Suitable for
Data center aggregation and spine-to-leaf uplinks requiring 100G long-reach links
Carrier and metro point-to-point connections up to 40 km
Inter-building and campus backbone connections over singlemode fiber
High-density QSFP28 deployments where fiber pair conservation is desired

How to use
Install the QSFP28 transceiver into a compatible QSFP28 port on a switch, router, or media converter following the host equipment manufacturer’s insertion and removal guidelines. Use singlemode fiber with LC-Duplex connectors and ensure correct end-to-end polarity. Verify link status and diagnostic parameters via the host device management interface that reports DDM metrics. Observe manufacturer recommendations for electrostatic discharge (ESD) protection when handling the module and keep dust caps on the connector until final cabling to avoid contamination.
Usage recommendations
For reliable long-reach operation, use ITU‑compliant singlemode fiber and maintain clean LC connectors. Monitor DDM parameters during commissioning and periodically in operation to detect early signs of signal degradation. Ensure the host port supports QSFP28 100GBASE-ER4 optics and check compatibility lists if available from the switch or router vendor.
