Optical Transceiver BlueOptics FN-TRAN-QSFP+LRI QSFP 25G — QSFP+ long-range 25Gbps

The BlueOptics FN-TRAN-QSFP+LRI QSFP 25G — QSFP+ long-range 25Gbps is an optical transceiver module designed for long-range 25 gigabit per second Ethernet links. It conforms to the QSFP+ form factor and provides four optical lanes in a single, hot-pluggable package. The module is intended for use in environments requiring compact, high-throughput uplink ports and extended fibre reach, such as data centers and carrier networks. It supports straightforward insertion into QSFP+ ports and enables the extension of fibre links with a single optical module.

Advantages

This QSFP+ optical transceiver offers long-range transmission capabilities while keeping a compact 4-lane QSFP+ footprint, which helps reduce port density constraints in racks and switches. The hot-pluggable design allows for maintenance or upgrades without powering down equipment. Optical connectivity reduces susceptibility to electromagnetic interference and supports stable, high-speed 25Gbps throughput. Compatibility with standard QSFP+ interfaces simplifies integration into existing network equipment with QSFP+ slots.

Key specifications

How to use

Install the transceiver by inserting it into a compatible QSFP+ port on a switch, router or media converter until it seats securely; follow the host equipment’s instructions for latching or securing the module. Connect appropriate single-mode fibre cables to the module’s optical interface, ensuring correct polarity and connector type. Verify link status using the host device LEDs or management interface and monitor link parameters. For safe removal, follow the host device’s hot-plug removal procedure to avoid signal disruption.

Recommendations

Use single-mode fibre and compatible connectors rated for long-range links; verify optical budget and link distance against the module’s long-range specification and the fibre characteristics. Ensure proper ESD precautions when handling the transceiver and avoid exposure of the optical ports to contaminants—use dust caps when the module is not connected. Confirm host compatibility with QSFP+ electrical and management interfaces to ensure stable operation.
