## Summary description

The BlueOptics H-ER4L4W-QSFP28-BO is a fiber optic transceiver module with a maximum data transfer rate of 100000 Mbit/s. It features a QSFP28 interface and a silver color. With a form factor of QSFP28 and a mean time between failures (MTBF) of 3000000 hours, it ensures reliability and performance. Weighing 40 g, it is lightweight and easy to install.

## Long description

The BlueOptics H-ER4L4W-QSFP28-BO is a QSFP28 fiber optic transceiver module designed for 100 Gbit/s optical links. It uses an LC duplex connection and complies with MSA form-factor standards for QSFP28 modules. The transceiver supports long-reach ER4 Lite transmission over singlemode fiber with CWDM for transmit and receive paths, and integrates Digital Diagnostics Monitoring (DDM/DOM) for real-time status of voltage, temperature and optical power. The module is lightweight (approx. 40 g), has a silver housing and is specified for reliable operation with a high MTBF.
Advantages
The module offers 100000 Mbit/s line-rate performance in a compact QSFP28 form factor suitable for modern 100G networks. Built to MSA compatibility and tested for interoperability, it incorporates CWDM optics and DDM functionality to support monitoring and troubleshooting. Use of proven optical and IC components contributes to extended service life and high availability, while the LC duplex interface ensures broad compatibility with standard fiber patching equipment.
Suitable for
High-speed uplinks and aggregation links in data centers and campus networks
Interconnection between switches, routers and storage systems over singlemode fiber
Long-reach optical links up to the ER4 Lite range where 100 Gbit/s capacity is required
Environments requiring remote monitoring via DDM/DOM

How to use
Install the BlueOptics QSFP28 transceiver into a compatible QSFP28 slot on a switch, router or other networking device following the host vendor’s hot‑swap and electrostatic discharge (ESD) procedures. Connect LC duplex singlemode patch cables to the transceiver ports, respecting transmit/receive orientation. Enable and verify link status on the host device; if supported, use the DDM/DOM interface to monitor optical power, temperature and supply voltage. Ensure that the connected equipment supports QSFP28 modules and the intended ER4 Lite wavelength plan.
Usage recommendations
Use certified singlemode LC duplex patch cables and, where possible, verify compatibility with the target hardware platform. Keep fiber connectors clean and observe ESD precautions during handling. When using DDM/DOM, confirm host support for diagnostic access to obtain real-time optical parameters for troubleshooting and preventive maintenance.
