Product information

Description

The BlueOptics QSFP-40G-ESR4-BO is a QSFP fiber optic transceiver module designed for high-speed 40 Gigabit Ethernet links over multimode fiber. It supports a maximum data transfer rate of 40 Mbit/s at an operating wavelength of 850 nm and uses an MPO/MTP fiber connector for parallel optical connections. The module features a durable metal housing, a compact lightweight design (approx. 40 g) and a high MTBF rating of 1,000,000 hours to support continuous operation in network equipment that accepts QSFP 40G modules.

Advantages

The transceiver provides compatibility with common QSFP-compliant hardware and supports 40GBASE-ESR4 multimode transmission up to 300 m. Its MPO/MTP connector enables parallel transmit and receive lanes for aggregated high-bandwidth links. Built to MSA specifications, the module includes digital diagnostic monitoring capabilities for real-time status of supply voltage, laser bias, optical output and input power and temperature when the host supports DDM/DOM. The metal housing and component selection contribute to long service life and stable operation in data-center and enterprise environments.

Suitable for

  • 40 Gigabit Ethernet backbone and aggregation links in data centers
  • Interconnects between switches, routers and storage systems over multimode fiber
  • High-speed links requiring MPO/MTP parallel optics up to 300 m
  • Environments where digital diagnostics (DDM/DOM) are used for monitoring

Key specifications

  • Interface type: QSFP (40 Gigabit Ethernet)
  • Optical wavelength: 850 nm (Tx/Rx)
  • Maximum data transfer rate: 40 Mbit/s
  • Maximum transmission distance: up to 300 m over multimode fiber
  • Connector type: MPO/MTP
  • Housing: metal
  • Weight: approximately 0.04 kg
  • Digital diagnostics: supported (DDM/DOM) when host hardware supports the feature
  • MTBF: 1,000,000 hours

How to use

Install the QSFP transceiver into a compatible QSFP slot on your switch, router or storage device according to the host vendor's hot‑swap and handling procedures. Connect an MPO/MTP multimode fiber patch cord between the transceiver and the mating optical device or patch panel, ensuring correct orientation and secure connector latching. Verify that the host recognizes the module and, if required, enable or confirm support for digital diagnostics to view real‑time parameters. Follow ESD precautions and manufacturer guidelines during insertion and removal to avoid damage.

Usage recommendations

Use high-quality multimode fiber patch cords and MPO/MTP connectors rated for 40G applications to achieve the specified range and performance. Ensure the host platform supports 40GBASE-ESR4 and DDM/DOM if diagnostic monitoring is needed. Clean connectors before mating and maintain proper bend radius for fiber cabling to prevent signal degradation.
