Fiber optic transceiver module BlueOptics 1000669-BO QSFP28 2000m

The BlueOptics 1000669-BO QSFP28 2000m is a fiber optic transceiver module designed for 100G optical links over single‑mode fiber up to 2 kilometres. It uses a QSFP28 interface with an LC duplex connector, an aluminium housing and a compact, lightweight form factor (approx. 40 g). The module implements 100GBASE‑CWDM4 signalling and supports common high‑speed network protocols for data centre and carrier applications.

Advantages

This QSFP28 transceiver provides high data throughput with low electromagnetic susceptibility inherent to fiber optic transmission. The aluminium enclosure offers mechanical protection while keeping weight low for dense installations. The module follows MSA pinout and form‑factor guidelines to work with compatible hardware platforms and supports digital diagnostics for remote monitoring of supply voltage, laser bias, output and received optical power, and internal temperature when the host system exposes DDM/DOM. Built and tested to industry component standards, the transceiver is intended for reliable long‑term operation.

Suitable for

• 100 Gbps Ethernet links in data centres
• High‑speed interconnects between switches, routers and storage systems
• Carrier and metro networks requiring single‑mode CWDM optics
• Environments where EMI immunity and long reach (up to 2 km) are needed

Key specifications

• Optical standard: 100GBASE‑CWDM4
• Connector: LC duplex
• Medium: Single‑mode fiber
• Maximum reach: up to 2000 m
• Housing material: aluminium

• Supports digital diagnostics monitoring (DDM/DOM) if supported by host

How to use

Insert the QSFP28 module into a compatible QSFP28 receptacle on the host device following the equipment manufacturer’s hot‑swap and handling guidelines. Connect LC duplex single‑mode fiber patch cords to the module ports, observing correct transmit/receive polarity. Ensure the host device supports 100GBASE‑CWDM4 optics and, if needed, enable or verify DDM/DOM monitoring in the system management interface. Allow a short link negotiation period after insertion and verify link status and optical power levels via the host or management tools.

Recommendations

Use high‑quality single‑mode LC duplex patch cords and clean connectors before making connections. Confirm compatibility with the specific switch, router or storage platform and the supported firmware versions. Avoid mechanical stress on fiber and module during installation and operate the module within the manufacturer’s specified temperature and power ranges for reliable long‑term performance.
