## Summary description

The BlueOptics QSFP-40G-ESR4-CH-BO is a fiber optic transceiver module with a maximum data transfer rate of 40 Mbit/s and operates at 850 nm. It features a QSFP interface and has a mean time between failures (MTBF) of 1,000,000 hours. Weighing 40 g, it is designed for reliable data transmission in networking applications.

## Long description

The BlueOptics QSFP-40G-ESR4-CH-BO is a QSFP fiber optic transceiver module designed for 40 Gigabit Ethernet links over multimode fiber. It operates at a wavelength of 850 nm, uses an MPO/MTP fiber connector and supports optical transmission distances up to 300 m. The module has a compact form factor, a reported weight of 40 g and an MTBF of 1,000,000 hours for continuous operation in networking equipment that supports QSFP interfaces.
Advantages
This QSFP transceiver follows MSA-compliant QSFP specifications and is built for interoperability with hardware platforms that support the corresponding 40GBASE-ESR4 type modules. The transceiver supports bidirectional optical laser transmission on multimode fiber and includes digital diagnostic monitoring capability for remote measurement of supply voltage, laser bias current, transmit power, receive power and temperature. Components are selected to meet industrial quality standards and to provide extended operational lifetime and stable optical performance.
Suitable for
40 Gigabit Ethernet uplinks and switch-to-switch connections over multimode fiber
Data center aggregation links and server connectivity within campus or short-reach environments
High-speed applications such as Ethernet, Fibre Channel over Ethernet and SDH/SONET within specified distance limits
Key specifications
Interface type: QSFP (quad small form-factor pluggable)
Maximum data transfer rate: 40 Mbit/s
Wavelength: 850 nm (transmit and receive)
Fiber connector: MPO/MTP
Maximum transfer distance (multimode fiber): up to 300 m
Supported protocols: 40GBASE-ESR4 and compatible high-speed Ethernet/FCoE/SDH implementations
Mean time between failures (MTBF): 1,000,000 hours
Weight: 0.04 kg
How to use
Install the QSFP module into a compatible QSFP port on a switch, router or other network device while the host device is powered down or following the vendor's hot-plug guidelines. Connect an MPO/MTP multimode fiber patch cord between the transceiver and the corresponding port or patch panel. Verify link status and, if available, enable or query the Digital Diagnostic Monitoring (DDM/DOM) features via the host system to monitor optical parameters. Ensure that the host device officially supports 40GBASE-ESR4 type modules and that firmware or driver settings allow third-party transceivers if required.
Usage recommendations
Use OM3/OM4 multimode fiber for reliable 300 m reach and pair the transceiver with MPO/MTP patch cords and compatible patch panels. Confirm DDM/DOM support on the host hardware for remote diagnostics and perform link verification after installation. Follow ESD handling precautions and factory-recommended insertion/removal procedures to avoid damage to the module and fiber connectors.
