QSFP Transceiver Module BlueOptics QSFP-100G-SL4-BO Fiber Optic QSFP28 MTP/MPO

The BlueOptics QSFP-100G-SL4-BO is a QSFP28 fiber optic transceiver module designed for 100 Gigabit Ethernet links over multimode fiber. It uses an MTP/MPO connector and an 850 nm optical interface to support short-reach 100GBASE-SR4 connections up to 100 m. The housing is aluminium and the module weighs approximately 40 g, offering a compact, industry-standard pluggable solution for high-density network equipment.

Advantages

The module is compatible with MSA-compliant QSFP28 ports and supports simultaneous transmit and receive channels via the MPO/MTP interface. Constructed with durable aluminium, it provides a lightweight form factor suitable for high-density racks. The transceiver supports industry-standard digital diagnostics (DDM/DOM) for real-time monitoring of parameters such as supply voltage, laser bias current, optical output and input power, and temperature, which simplifies remote maintenance and troubleshooting.

How to use

Insert the QSFP-100G-SL4-BO module into a compatible QSFP28 port on switches, routers or other network equipment while following the host device manufacturer’s hot-plug and handling instructions. Connect an appropriate MPO/MTP multimode fiber patch cable to the module’s connector, ensuring correct polarity and proper mating. Verify link status and, if supported, read digital diagnostics information from the host system to confirm optical power levels and operating temperature.

Recommendations

Use multimode fiber (OM3/OM4) certified for 100GBASE-SR4 to achieve the specified 100 m reach. Ensure the host equipment supports QSFP28 transceivers and DDM/DOM if you intend to use diagnostic features. Handle the module with ESD precautions and keep dust caps on the connector when not in use to maintain performance and longevity.
