BlueOptics QSFP-100G-CWDM-C-BO network transceiver module Fiber optic 100000 Mbit/s QSFP28

The BlueOptics QSFP-100G-CWDM-C-BO is a 100G QSFP28 fiber optic transceiver module designed for high-speed single-mode fiber applications. It supports a maximum data transfer rate of 100000 Mbit/s, uses a QSFP28 interface and LC duplex connector (CWDM4), and is housed in a compact metal casing with a supply voltage of 3.3 V. The module is compatible with hardware that supports 100GBASE-CWDM4 transceivers and is intended for use in switches, routers and storage systems that accept QSFP28 form-factor modules.

Advantages

This BlueOptics QSFP28 module provides a standardized QSFP28 interface and CWDM4 optical channels for reliable 100 Gbit/s transmission over single-mode fiber. The metal housing and lightweight design support simple installation and physical compatibility with common QSFP28 ports. Digital diagnostics (DDM/DOM) capability allows real-time monitoring of supply voltage, laser bias current, transmitter output power, receiver input power and internal temperature when supported by the host hardware. The module follows MSA-compatible specifications and is engineered to deliver consistent optical performance for short to medium reach single-mode links.

Key specifications

How to use

Insert the QSFP28 module into a compatible QSFP28 port on a switch, router or other network device while the host equipment is powered off or following the manufacturer's hot‑swap guidelines. Connect LC duplex single-mode fiber patch cords to the module's LC connector, ensuring correct TX/RX orientation. Verify that the host device recognizes the module and that DDM/DOM monitoring is enabled if supported. Use appropriate network configuration and diagnostics tools to confirm 100G link negotiation and optical signal levels.

Recommendations

To achieve optimal performance, use single-mode fiber and high-quality LC duplex patch cords, observe proper ESD precautions during handling, and ensure that the host device firmware supports CWDM4 QSFP28 transceivers and DDM/DOM monitoring. For stable long-term operation, follow the equipment vendor's compatibility list and test a sample module in the target hardware before deploying at scale.
