QSFP-lähetin-vastaanotinmoduuli BlueOptics QSFP-40G-CSR4-MM850-BO 40 Gbit/s 850 nm

BlueOptics QSFP-40G-CSR4-MM850-BO is a QSFP transceiver module that supports a 40 Gbit/s aggregate data rate using 850 nm multimode optics. The module integrates four 10 G lanes in a single QSFP form factor, enabling short-reach aggregated links between switches, servers, and other high-speed networking equipment in data center environments where multimode fiber is used.

Advantages

This QSFP transceiver provides a compact, hot-pluggable solution for 40G Ethernet interconnects over multimode cabling. The 850 nm VCSEL-based optics are optimized for short-reach links and offer compatibility with MPO/MTP and parallel multimode fiber infrastructures. Its QSFP form factor consolidates four 10 G lanes into a single module, reducing port density and cabling complexity while maintaining a standard interface for easy integration into compatible switches and media converters.

Suitable for

• 40G Ethernet links in data centers using multimode fiber
• Short-reach aggregated connections between switches and servers
• High-density uplinks and spine-leaf network architectures
• Parallel multimode fiber installations with MPO/MTP cabling

Key specifications

• Aggregate data rate: 40 Gbit/s delivered as four independent 10 G lanes
• Operating wavelength: 850 nm multimode optics
• Optical interface: QSFP package with parallel multimode fiber support
• Reach: designed for short-reach multimode links (data center distances)
• Application: 40G Ethernet and compatible high-speed interconnects

How to use

Insert the QSFP module into a compatible QSFP port on a switch, router, or media converter while the host device is powered per vendor guidelines to support hot-pluggable operation. Connect the module to the parallel multimode fiber cable assembly (typically MPO/MTP) ensuring correct polarity and secure connections. Configure the host port for 40G operation if required by the network equipment, and verify link status through the device management interface or LED indicators.

Recommendations

Use this transceiver with multimode fiber rated for the appropriate link distance and with compatible MPO/MTP cabling assemblies. Verify that the host equipment supports the QSFP transceiver type and 40G multimode operation. For reliable performance, follow data center cabling best practices: maintain clean connectors, observe bend radius limits for multimode fiber, and confirm polarity and channel mapping before activating the link.
