Módulo transceptor QSFP BlueOptics QSFP-40G-ISR4-BO 40000 Mbit/s 850 nm

The BlueOptics QSFP-40G-ISR4-BO is a QSFP fiber optic transceiver module engineered for 40 Gbit/s data transmission over multimode fiber. Operating at 850 nm wavelength and using an MPO/MTP-compatible optical interface, this compact module (approx. 20 g) supports 40GBASE-SR4 applications and fits QSFP ports that adhere to MSA electrical and mechanical specifications. It is designed for use in networking equipment that supports QSFP 40G SR4 transceivers and provides digital diagnostics (DDM/DOM) functionality when the host device supports these features.

Advantages

The module delivers 40 Gbit/s aggregated bandwidth through a QSFP form factor, enabling simultaneous transmit and receive channels over multimode fiber. Compliance with MSA QSFP standards ensures mechanical and electrical interoperability with a wide range of switches, routers and storage systems. The transceiver supports optical diagnostic reporting (DDM/DOM) for monitoring supply voltage, laser bias current, optical output and input power and temperature, aiding remote maintenance and fault analysis.

How to use

Install the BlueOptics QSFP-40G-ISR4-BO by inserting it into a compatible QSFP port on switches, routers or servers while following the host vendor's hot-plug and handling guidelines. Connect multimode MPO/MTP patch cords or breakout cables according to the 40GBASE-SR4 channel mapping and ensure fiber polarity and pinning match the connected equipment. Verify the host device recognizes the transceiver and, if available and required, enable or read DDM/DOM parameters through the management interface to monitor operational status.

Recommendations

Use high-quality multimode fiber (OM3/OM4 or as specified by your network design) and MPO/MTP cables certified for 40G operation. Confirm host compatibility with QSFP SR4 modules and check that DDM/DOM support is available if remote diagnostics are required. Follow ESD precautions and manufacturer handling guidelines during installation and store the module in a clean, dry environment when not in use.
