Product information

Description

The BlueOptics QSFP-40G-ESR4-MT-BO is a compact QSFP fiber optic transceiver module designed for 40 Mbit/s high-speed optical links. Operating at an 850 nm wavelength with an MTP/MPO connector, the module supports multimode fiber transmission over distances up to 300 m. With a lightweight 40 g housing and an MTBF of 1,000,000 hours, this transceiver is intended for integration into network switches, routers, storage systems and other 40 Gigabit Ethernet platforms that accept QSFP form-factor optics.

Advantages

This BlueOptics QSFP transceiver provides standardized MSA-compliant electrical and mechanical interfaces for broad interoperability and straightforward integration. The 850 nm transmitter and receiver are optimized for multimode fiber, delivering low-latency simultaneous send/receive capability via MPO/MTP connections. Designed with quality components and tested for compatibility, the module offers a long operational life and digital diagnostics support for remote monitoring when the host hardware supports DDM/DOM.

Suitable for

  • 40 Gigabit Ethernet uplinks and high-speed server interconnects
  • Switch-to-switch and router-to-router optical links within data centers
  • Storage area network (SAN) connectivity and high-throughput applications
  • Short-reach multimode fiber runs up to 300 m in enterprise and campus networks

Key specifications

  • Data rate: 40 Mbit/s
  • Wavelength: 850 nm (transmit and receive)
  • Maximum transfer distance: 300 m (multimode fiber)
  • Connector type: MTP/MPO
  • Interface: 40 Gigabit Ethernet (QSFP form factor)
  • Weight: 0.04 kg
  • Mean time between failures (MTBF): 1,000,000 hours

How to use

Install the QSFP transceiver into a compatible QSFP slot on a switch, router or other network device following the host manufacturer's hot-plugging and electrostatic discharge (ESD) handling guidelines. Connect an appropriate MTP/MPO multimode fiber patch cord between transceivers or to a patch panel. Verify link parameters in the host device management interface and, if available, enable or read Digital Diagnostic Monitoring (DDM/DOM) to monitor supply voltage, laser bias current, optical output and input power, and module temperature.

Usage recommendations

For reliable short-reach operation, use high-quality OM3/OM4 multimode fiber and certified MTP/MPO patch cords, ensure proper connector cleaning before mating, and confirm host hardware compatibility with QSFP-40G multimode modules and DDM/DOM features. Follow vendor guidelines for temperature and handling to maintain the specified MTBF and transmission performance.

Specifications

Wavelength: The distance over which a wave repeats itself. The wavelength determines the characteristics of the wave e.g. red light has a different wavelength to blue light.
850 nm
Maximum transfer distance: The greatest distance over which the data/signal can be transferred.
300 m
Maximum data transfer rate: The maximum speed with which data can be transmitted from one device to another.
40 Mbit/s
Fiber optic connector: This terminates the end of an optical fiber, and enables quicker connection and disconnection than splicing. The connectors mechanically couple and align the cores of fibers so light can pass. Better connectors lose very little light due to reflection or misalignment of the fibers. In all there have been about 100 types of optic fiber connectors produced.
