BlueOptics MA-QSFP-100G-SR4-BO network transceiver module Fiber optic 100000 Mbit/s QSFP28 850 nm

The BlueOptics MA-QSFP-100G-SR4-BO is a fiber optic QSFP28 network transceiver module designed for 100000 Mbit/s (100G) short-reach multimode links. It operates at an 850 nm wavelength and uses an MPO/MTP-style multi-fiber interface following MSA guidelines. The module is compact and lightweight (approx. 40 g) and intended for use in data center switches, routers and other high-performance networking equipment that support 100GBASE-SR4 QSFP28 transceivers.

Advantages

The transceiver supports 100GBASE-SR4 multimode operation with simultaneous transmit and receive channels and is compatible with industry MSA QSFP28 form-factor interfaces. It includes digital diagnostic monitoring (DDM/DOM) capability for real-time readouts such as optical power and temperature when supported by host hardware. The MPO/MTP connector design enables parallel multimode fiber connections for distances appropriate to SR4 implementations.

How to use

Install the BlueOptics QSFP28 module into a compatible QSFP28 slot on a switch, router or other network device while the host system is powered down or following the vendor's hot-plug guidelines. Connect an MPO/MTP multimode fiber patch cord to the module and route the cable to the remote transceiver or patch panel. Verify link status and, if available, check digital diagnostics (DDM/DOM) via the host device management interface to confirm optical power, temperature and module voltage within expected ranges. Ensure the host device firmware supports third-party transceivers where required.

Recommendations

Use OM3/OM4 multimode fiber for reliable 100GBASE-SR4 performance and adhere to recommended polarity and MPO/MTP pinout. Keep optical connectors clean and inspect before insertion. Confirm host compatibility with QSFP28 100GBASE-SR4 modules and enable DDM/DOM monitoring if needed for remote diagnostics.
