## Summary description

The BlueOptics EX-QSFP-40GE-SR4-BO is a fiber optic network transceiver module designed for high-speed data transmission. It features a QSFP interface and MPO connector, ensuring compatibility with various network setups. Weighing only 20g, this aluminum module is lightweight and efficient, making it ideal for data centers and enterprise networks.

## Long description

The BlueOptics EX-QSFP-40GE-SR4-BO is a 40GBASE-SR4 fiber optic QSFP transceiver module with an MPO/MTP multi-fiber connector and QSFP interface. Designed for multimode fiber links, it supports simultaneous transmit and receive channels at 850 nm and is intended for use in data centers and enterprise network equipment that accept compatible QSFP modules. The module is lightweight (approximately 20 g) and housed in an aluminium enclosure to provide mechanical stability and thermal dissipation for high-speed operation.
Advantages
This BlueOptics QSFP transceiver follows MSA standards and is engineered to be compatible with major hardware platforms that support equivalent 40GBASE-SR4 QSFP modules. It supports high-throughput Ethernet, Fibre Channel over Ethernet and SDH/SONET applications up to 40 Gbit/s over multimode fiber. The module is produced using industry-grade components to improve reliability and lifetime, and it includes digital diagnostics monitoring (DDM/DOM) for real-time optical and electrical parameter reporting when supported by the host hardware.
Suitable for
40 Gbit/s short-reach links in data center switch-to-switch connections
High-bandwidth uplinks between aggregation and core switches
Multimode fiber interconnects for storage and server clusters
Environments requiring MPO/MTP connectivity for parallel optics
Key specifications
Form factor: QSFP (Quad Small Form-factor Pluggable)
Data rate: up to 40 Gbit/s (40GBASE-SR4)
Wavelength: 850 nm for transmitter and receiver
Fiber type: Multimode fiber (MMF)
Connector: MPO/MTP multi-fiber connector
Typical reach: designed for short-reach multimode links (see system-specific reach limits)
Housing material: aluminium
Weight: approximately 0.02 kg
Monitoring: digital diagnostics (DDM/DOM) supported when host hardware allows
How to use
Install the BlueOptics QSFP module into a compatible QSFP slot on a switch, router or other network device while the device is powered down or hot-swap according to the host platform’s instructions. Connect an MPO/MTP multimode fiber patch cord to the module and route the other end to the corresponding MPO/MTP transceiver or patch panel. Verify that the host device recognizes the transceiver and, if available, enable or query DDM/DOM to monitor supply voltage, laser bias current, transmit power, receive power and module temperature. Ensure that the multimode fiber type and patching comply with the required cable specification for 40GBASE-SR4 links.
Usage recommendations
Use high-quality multimode MPO/MTP patch cords and adhere to the host vendor’s compatibility list for best results. Confirm DDM/DOM support in the host to access diagnostic parameters, and follow recommended cleaning and handling procedures for fiber connectors to maintain optimal optical performance.
