40G QSFP-transceiver BlueOptics 40G-QSFP-LR4-1-BO 40000 Mbit/s

The BlueOptics 40G-QSFP-LR4-1-BO is a 40 Gigabit QSFP fiber optic transceiver module designed for long-reach single-mode links. It supports a maximum data transfer rate of 40,000 Mbit/s and LC fiber connectors, with an operational range up to 10,000 m. The module comes in a compact, silver housing and has a high mean time between failures (MTBF) of 1,000,000 hours, providing a reliable optical interface for switches, routers and media converters that accept QSFP form factors.

Advantages

The transceiver offers a standardized QSFP interface for easy hot-plug installation and interoperability with compatible networking equipment. Its long maximum transfer distance and LC connector type make it suitable for single-mode fiber backbones and long-haul links. The lightweight, compact silver enclosure minimises space and weight impact in high-density chassis, while the high MTBF indicates stable operation and reduced maintenance intervals.

Suitable for

• Long-reach single-mode fiber connections in data centers
• Interconnects between switches and routers supporting 40 Gigabit Ethernet
• Telecom and carrier aggregation links over single-mode fiber
• Upgrading or expanding network equipment with QSFP ports

How to use

Install the BlueOptics QSFP transceiver into a compatible QSFP port on your switch, router or media converter while the port supports hot-plug insertion. Connect LC-terminated single-mode fiber patch cables to the transceiver's LC duplex ports, ensuring correct polarity and secure connectors. Configure the network device for 40 Gigabit Ethernet operation and verify link status via the device management interface. Follow equipment vendor guidelines for safe insertion and removal to avoid damage.

Recommendations

Use single-mode LC patch cables rated for long-reach transmission and observe proper cable routing to minimise bend radius and signal loss. Verify compatibility with the host device's QSFP transceiver support list and update device firmware if necessary to ensure stable link negotiation at 40 Gbit/s.
