## Summary description

QSFP28 100GBASE‑CWDM4 transceiver from BlueOptics for singlemode fiber links. LC‑Duplex connector, 4‑channel WDM supporting 100 Gbit/s over up to 2 km, with DDM/DOM diagnostics and operating range 0–70°C. Designed for data center and backbone connections where compact 100G optics and link monitoring are required.

## Long description

The BlueOptics QSFP28 Transceiver 100GBASE‑CWDM4 LC‑Duplex Singlemode is a compact optical module designed for 100 Gbit/s links over singlemode fiber. It implements CWDM4 wavelength division multiplexing across four channels and uses an LC‑Duplex connector interface. The module supports link distances up to 2 km and includes DDM/DOM diagnostics for real‑time monitoring of optical parameters. The transceiver operates in typical data center temperature ranges and fits QSFP28 ports used in switches, routers and servers for high‑density 100G connectivity.
Advantages
This transceiver provides dense 100G connectivity in a small QSFP28 form factor while using LC‑Duplex singlemode cabling. The CWDM4 design enables aggregation of four wavelengths into a single fiber pair, reducing fiber count compared with parallel solutions. Integrated DDM/DOM enables monitoring of power, temperature and transmit/receive performance for simplified troubleshooting and maintenance. The module's rated distance of up to 2 km covers many intra‑data‑center and short‑reach backbone scenarios, and the operating temperature range supports standard equipment room environments.
Suitable for
High‑density 100G links within data centers and server rooms
Short‑reach backbone connections between switches or aggregation points up to 2 km
Network upgrades where reduced fiber count and LC‑Duplex interfaces are required
Environments requiring optical diagnostics and link monitoring

How to use
Install the QSFP28 transceiver into a compatible QSFP28 port on switches, routers or network interface cards, ensuring the module is fully seated and the device recognizes the optics. Connect LC‑Duplex singlemode patch cables between transceivers at each link end, observing proper fiber polarity. Use network equipment management interfaces to verify link status and monitor DDM/DOM parameters such as optical power and temperature. Ensure connected devices are configured for 100G operation and for any required transport or encoding schemes supported by 100GBASE‑CWDM4.
Usage recommendations
For reliable operation, use low‑loss singlemode LC patch cables and maintain clean fiber connectors. Verify compatibility with host equipment and firmware that supports QSFP28 100GBASE‑CWDM4 modules. Monitor DDM/DOM outputs after installation to confirm optical levels and module health, and keep ambient temperatures within the specified 0–70°C range for optimal performance.
