Product information

Description

The BlueOptics QSFP-40G-ESR4-EE-BO is a QSFP fiber optic transceiver module designed for 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 MTP/MPO connector for parallel optical lanes. With a compact, lightweight design (approximately 40 g) and an MTBF of around 1,000,000 hours, this module is intended for use in switches, routers, storage systems and other equipment that accept MSA-compliant QSFP modules.

Advantages

The module follows MSA QSFP form-factor standards and provides interoperability with hardware platforms that support the corresponding QSFP-40G-ESR4 profile. It implements simultaneous transmit and receive functionality over multimode fiber via an MPO/MTP interface and includes digital diagnostics monitoring (DDM/DOM) for real-time monitoring of supply voltage, laser bias current, output power, received power and temperature. Built with components chosen for reliability, the transceiver is intended to deliver long operational life and reduced maintenance needs.

Suitable for

  • 40 Gigabit Ethernet connections in data centers and aggregation layers
  • High-speed interconnects between switches, routers and storage arrays
  • Fibre Channel over Ethernet (FCoE) links and SDH/SONET transport
  • Short-reach multimode fiber links up to 300 m

Key specifications

  • Data rate: up to 40 Mbit/s
  • Wavelength: 850 nm (Tx/Rx)
  • Max transmission distance: up to 300 m over multimode fiber
  • Interface: QSFP (40 Gigabit Ethernet)
  • Connector type: MPO / MTP
  • Module weight: approx. 0.04 kg
  • Digital diagnostics: DDM/DOM (MSA SFF-8472 compliant)
  • Form factor: QSFP, MSA-compliant

How to use

Install the BlueOptics QSFP-40G-ESR4-EE-BO by inserting it into a compatible QSFP port on the target device following the equipment manufacturer’s hot-swap and handling instructions. Connect an appropriate MPO/MTP multimode fiber patch cord between transceivers or to a patch panel, ensuring correct polarity and proper fiber type (multimode). If your platform supports digital diagnostics monitoring, enable or query DDM/DOM through the host system to view real-time optical and electrical parameters. Observe electrostatic discharge (ESD) precautions and keep protective dust caps on the connector when not in use.

Usage recommendations

For best performance, use certified multimode fiber and MPO/MTP patch cords rated for 850 nm transmission, verify compatibility with the host hardware’s supported QSFP profiles, and confirm that DDM/DOM is supported if remote diagnostic monitoring is required. Maintain clean connectors and follow the device vendor’s installation guidance to achieve the specified reach and reliability.
