Product information

Description

The BlueOptics QSFP-40G-ESR4-BR-BO is a QSFP fiber optic transceiver module designed for 40 Mbit/s multimode optical links using 850 nm wavelength. Built to MSA QSFP form-factor specifications, the module provides a compact MPO/MTP interface for simultaneous transmit and receive over multi-mode fiber. The transceiver features digital diagnostic monitoring (DDM/DOM) support for real-time reporting of supply voltage, laser bias current, transmit power, receive power and temperature, and is specified with a mean time between failures (MTBF) of 1,000,000 hours. Weighing 40 g, it is lightweight and suitable for hot-swap installation in compatible network equipment.

Advantages

The module supports standardized QSFP connectivity and MPO/MTP termination for dense optical deployments, offering interoperability with systems that accept QSFP MSA-compliant transceivers. Integrated DDM/DOM simplifies remote monitoring and fault analysis. Compliance with recognized industrial standards and the use of high-quality optical components contribute to extended operational lifetime and high availability in data center and enterprise environments.

Suitable for

  • 40 Mbit/s multimode fiber links in data center aggregation and spine-leaf networks
  • High-density switch, router and storage interfaces requiring QSFP modules
  • Environments that require remote optical diagnostics and continuous monitoring
  • Short-reach connections up to the validated multimode distance using 850 nm optics

Key specifications

  • Interface type: QSFP (MPO/MTP connector)
  • Wavelength: 850 nm
  • Maximum data transfer rate: 40 Mbit/s
  • Fiber type: Multi-mode fiber (MMF)
  • Digital diagnostics: DDM/DOM (real-time supply voltage, bias current, TX/RX power, temperature)
  • Mean time between failures (MTBF): 1,000,000 hours
  • Weight: 0.04 kg

How to use

Insert the QSFP module into a compatible QSFP port on a switch, router or storage appliance while the host is powered according to the equipment vendor’s hot-swap guidelines. Connect an MPO/MTP multimode fiber patch cord to the module’s connector, ensuring correct polarity and proper fiber type for 850 nm operation. If supported by the host, enable DDM/DOM monitoring through the device management interface to view real-time optical parameters and facilitate troubleshooting. Follow the network equipment vendor’s instructions for firmware and compatibility when deploying third‑party transceivers.

Usage recommendations

Use high-quality multimode fiber patch cords and compatible MPO/MTP adapters or patch panels to achieve optimal link performance. Verify the host platform supports QSFP MSA-compliant transceivers and DDM/DOM features if remote diagnostics are required. Perform end-to-end power budget and connector cleanliness checks during installation and periodic maintenance to maintain signal integrity.
