Optical Transceiver BlueOptics FN-TRAN-QSFP28-ER 100G ER up to 40 km

BlueOptics FN-TRAN-QSFP28-ER 100G ER up to 40 km is a QSFP28 optical transceiver module engineered for 100 Gigabit Ethernet links that require extended reach. The module supports single-mode fiber connections and is intended for metro, aggregation, core and data center interconnect applications where reliable long-distance transmission up to 40 km is required. It is compatible with devices that accept QSFP28 form-factor modules and provides a compact, hot-pluggable solution for upgrades and new installations.

Advantages

This optical transceiver offers extended reach performance up to 40 km over single-mode fiber while using the QSFP28 form factor to carry 100G Ethernet traffic. The module provides a standardized interface for easy installation in compatible ports, supports high-density deployments thanks to its compact size, and is suitable for scenarios that require stable long-distance optical links. The design focuses on interoperability with standard QSFP28 ports and predictable optical performance for network expansions.

Suitable for

• Metro and carrier networks requiring 100G long-reach links
• Data center interconnects between sites up to 40 km apart
• Aggregation and core network uplinks with single-mode fiber
• Network upgrades where QSFP28 100G transceivers are needed

Key specifications

• Form factor: QSFP28
• Data rate: 100 Gigabit Ethernet
• Optical reach: up to 40 km on single-mode fiber
• Fiber type: single-mode fiber (SMF)
• Connector interface: standard QSFP28 optical interface

How to use

Install the module into a compatible QSFP28 port on a switch, router or media converter while the host device is powered according to the equipment manufacturer's hot-plug guidelines. Connect single-mode fiber patch cables to the transceiver’s optical interface, ensuring correct polarity and appropriate connector type on both ends. After physical installation, verify link status and configure the host device for 100G operation if necessary. Monitor signal and link diagnostics through the host device to confirm expected performance.

Usage recommendations

Ensure fiber connectors and transceiver optics are clean before connection and use single-mode fiber rated for long-reach transmission. Confirm compatibility with the host device's QSFP28 port and follow the network equipment vendor's guidance for module installation and firmware/driver requirements.
