QSFP28 Transceiver BlueOptics 740-061412 100000 Mbit/s LC

The BlueOptics QSFP28 Transceiver 740-061412 is a 100G optical module with an LC duplex interface designed for high-speed single‑mode fiber links. Housed in metal and weighing approximately 40 g, this QSFP28 supports up to 100000 Mbit/s data transfer and conforms to MSA dimensional and electrical specifications used in modern network hardware. The module implements CWDM wavelengths for transmit and receive channels and is intended for use in networking equipment that accepts QSFP28 100GBASE‑CWDM4 transceivers.

Advantages

This transceiver provides a compact QSFP28 form factor with an LC connector for duplex single‑mode fiber, enabling simultaneous transmit and receive over separate fibers. Metal construction offers durability and shielding against mechanical stress. The module supports standard digital diagnostic monitoring (DDM/DOM) features where supported by host hardware, allowing remote readout of supply voltage, laser bias current, optical output and input power, and temperature. Designed to be compatible with equipment that accepts 100GBASE‑CWDM4 QSFP28 transceivers, it fits use cases that require reliable, high‑speed optical connectivity.

Suitable for

• Data center 100G uplinks and aggregation links
• Core and distribution switch interconnects over single‑mode fiber
• High‑performance routers and storage system links supporting QSFP28
• Environments requiring CWDM 100G optical connections up to medium ranges

How to use

Install the QSFP28 transceiver into a compatible QSFP28 port on a switch, router or other networking device following the host vendor’s insertion and removal procedure. Connect LC duplex single‑mode fiber patch cords to the transceiver’s LC sockets, ensuring correct polarity for transmit and receive fibers. Verify link status and negotiated speed in the host system management interface. If the host supports DDM/DOM, monitor the module’s diagnostic parameters through the device management tools to confirm proper operation and optical power levels.

Recommendations

Ensure the networking equipment explicitly supports 100GBASE‑CWDM4 QSFP28 modules and DDM if diagnostics are required. Use quality single‑mode LC patch cords and maintain correct fiber polarity. Observe electrostatic discharge (ESD) precautions when handling the transceiver and protect optical ports from contamination by using dust caps when connectors are not mated.
