Product information

Description

The BlueOptics QSFP-40G-ESR4-IT-BO is a compact QSFP transceiver module designed for 40 Gigabit Ethernet links over multimode fiber. It operates at an 850 nm wavelength, supports a maximum data rate of 40 Mbit/s and a maximum segment distance of up to 300 m using MTP/MPO connectors. With a lightweight form factor (approximately 40 g) and high MTBF, the module is intended for integration into switches, routers, storage systems and other networking hardware that accept MSA-compliant QSFP optics.

Advantages

The module follows QSFP MSA mechanical and electrical definitions to provide interoperability with compatible hardware platforms. It includes transmitter and receiver channels optimized for 850 nm multimode operation and uses an MTP/MPO fiber connector for parallel optical links. Built and tested to industry standards, the transceiver offers digital diagnostics capability for monitoring supply voltage, laser bias current, transmit power, receive power and temperature when supported by the host. The product’s compact size and low weight simplify installation in high-density environments.

Suitable for

  • 40 Gigabit Ethernet uplinks between switches and aggregation points
  • High-speed interconnects in data center racks up to 300 m over multimode fiber
  • Storage area network (SAN) and Fibre Channel over Ethernet deployments
  • Hardware platforms that support MSA-compliant QSFP transceivers with MTP/MPO interfaces

Key specifications

  • Nominal wavelength: 850 nm
  • Maximum data transfer rate: 40 Mbit/s
  • Maximum link distance over multimode fiber: 300 m
  • Interface type: 40 Gigabit Ethernet (QSFP)
  • Optical connector: MTP/MPO
  • Weight: approximately 0.04 kg
  • Mean time between failures (MTBF): 1,000,000 hours
  • Digital diagnostics (DDM/DOM) support when host hardware provides access

How to use

Install the QSFP-40G-ESR4-IT-BO into a QSFP port of a compatible switch, router or storage device while the host is powered off or following the host’s hot-plug guidance. Connect a suitable MTP/MPO multimode fiber patch cord to the transceiver and the remote device or patch panel. Ensure that the connected fibers and patch cords meet multimode specifications for 850 nm operation and the required channel distance. If the host supports digital diagnostics, enable or query the DDM/DOM interface to monitor operational parameters and assist with maintenance.

Usage recommendations

Use high-quality multimode MTP/MPO patch cords and maintain clean optical endfaces to ensure reliable optical performance. Verify host compatibility with MSA-compliant QSFP transceivers and confirm software/firmware support for DDM if real-time diagnostics are required. For longer runs or single-mode requirements, select an appropriate single-mode transceiver designed for the desired wavelength and distance.
