Transceptor de fibra ótica BlueOptics BO25K859S2D 40000 Mbit/s QSFP 850 nm

The BlueOptics BO25K859S2D is a fiber optic transceiver module engineered for 40 Gigabit Ethernet environments. With a QSFP form factor and an operating wavelength of 850 nm, this module supports a maximum data transfer rate of 40000 Mbit/s and is specified for multimode fiber links up to 150 m using MTP/MPO fiber connectors. It is designed to integrate with compatible switches, routers and media converters where high-throughput short-reach links are required.

Advantages

The BlueOptics BO25K859S2D offers reliable short-range 40 Gb/s connectivity in a compact QSFP package. Its 850 nm laser and MTP/MPO connector support standard multimode fiber infrastructures, enabling straightforward deployment in data center aggregation and switch-to-switch links. The module's specification for 150 m reach on multimode fiber provides flexibility for rack-to-rack and row-level interconnects while maintaining uniform signal quality suitable for high-density networking environments.

Suitable for

• Data center top-of-rack and spine-leaf interconnects
• High-speed switch-to-switch links within server rooms
• Short-reach multimode fiber installations up to 150 m
• Network upgrades requiring 40 Gigabit Ethernet ports

Key specifications

• Maximum data transfer rate: 40000 Mbit/s (40 Gb/s)
• Optical wavelength: 850 nm
• Interface type: QSFP for 40 Gigabit Ethernet
• Connector type: MTP/MPO multimode fiber connector
• Maximum transfer distance on multimode fiber: 150 m

How to use

Install the QSFP transceiver into a compatible QSFP port on the network device, ensuring the module seats fully and the device detects the transceiver. Connect an MTP/MPO multimode fiber cable between devices, observing correct polarity and bend-radius limits for the fiber. After physical installation, verify link status and speed on the network device management interface and perform any required link diagnostics or firmware checks according to the host device documentation.

Recommendations

Use multimode fiber (OM3/OM4) cables rated for 40 Gb/s links and keep cable runs within the 150 m specification. Ensure port compatibility and check host device transceiver support lists before purchase. Maintain clean connector end-faces and follow ESD handling practices when installing the module.
