QSFP transceiver module BlueOptics QSFP-40G-SR4-CI 40000 Mbit/s 850 nm

The BlueOptics QSFP-40G-SR4-CI 40000 Mbit/s 850 nm is a fiber optic transceiver module designed for short-range, high-speed connectivity in data centers and enterprise networks. Featuring a QSFP interface and multimode operation at 850 nm, this module supports aggregate data rates up to 40 Gbit/s and is intended for use in top-of-rack switches, aggregation layers, and other networking equipment that accepts QSFP modules.

Advantages

This QSFP transceiver provides a compact, hot-pluggable form factor with stable optical performance for short-reach links. Its support for 40 Gbit/s aggregate throughput and 850 nm wavelength makes it suitable for multimode fiber systems, enabling high-density deployment and low-latency transmission. The QSFP interface simplifies integration with compatible switches and servers while reducing cabling complexity compared with multiple parallel SFP links.

Suitable for

• Short-range data center connections over multimode fiber
• Top-of-rack and aggregation switch uplinks
• High-bandwidth server interconnects within racks
• Enterprise network segments requiring 40 Gbit/s links

Key specifications

• Form factor: QSFP (Quad Small Form-factor Pluggable)
• Maximum data transfer rate: 40000 Mbit/s (40 Gbit/s aggregate)
• Optical wavelength: 850 nm (multimode fiber)
• Application range: short-reach multimode fiber links
• Hot-pluggable transceiver module for compatible network equipment

How to use

Install the module into a compatible QSFP port on your switch, router or server according to the equipment manufacturer’s instructions. Ensure the connected multimode fiber cables and patch panels support 850 nm short-reach operation and are properly terminated. After insertion, verify link status and configure the network device ports as required for 40 Gbit/s operation. Remove the module by following hot-swap safety procedures if service or replacement is needed.

Recommendations

Use certified multimode fiber with appropriate patch cords and keep optical connectors clean to maintain signal quality. Verify compatibility with the host device’s QSFP port and firmware, and observe ESD precautions when handling the transceiver. For reliable short-reach performance, follow the fiber type and distance guidelines provided by the network equipment and cable manufacturers.
