Network QSFP transceiver BlueOptics BO25K13630D 40GBASE-ER4L 40Gbps 30 km

BlueOptics BO25K13630D is a QSFP form-factor optical transceiver implementing the 40GBASE-ER4L standard. The module provides an aggregate 40 Gbps throughput over single-mode fiber and supports link distances up to 30 km. Intended for long-reach uplinks and data center interconnects, this 40G QSFP transceiver connects QSFP ports on switches, routers and optical line equipment to extend high-capacity links across campus, metro and regional networks.

Advantages

The transceiver supports four-lane 10 Gbps signaling combined into a 40 Gbps aggregate, enabling efficient use of fiber infrastructure for long-reach connections. Its QSFP form factor offers high port density and hot-pluggable operation, simplifying installation and replacement without powering down host equipment. Designed for single-mode fiber, the module delivers stable performance over distances up to 30 km and is compatible with standard QSFP interfaces for broad interoperability.

Suitable for

• 40 Gbps uplinks between aggregation switches and core routers
• Data center interconnects over single-mode fiber
• Metro and regional optical links requiring 30 km reach
• High-density QSFP port deployments in telecom and enterprise networks

Key specifications

• Form factor: QSFP (Quad Small Form-factor Pluggable)
• Standard: 40GBASE-ER4L
• Aggregate data rate: 40 Gbps (4 × 10 Gbps)
• Fiber type: Single-mode fiber (SMF)
• Maximum link distance: up to 30 km
• Connector type: LC duplex (for single-mode fiber)
• Operating mode: Hot-pluggable

How to use

Insert the QSFP transceiver into a compatible QSFP port on the host device following the vendor’s hot-plug instructions. Connect single-mode fiber patch cords with LC duplex connectors to the module’s optical ports, ensuring correct transmit/receive orientation. Verify link status and configuration on the host device and confirm that the interface is set for 40G operation. Follow standard optical safety practices when handling fiber and avoid exposing the transceiver’s optical connectors to dust or contamination.

Recommendations

Use single-mode fiber with appropriate attenuation and dispersion budgets for runs approaching 30 km. Keep spare dust caps on the transceiver when not in use, and follow vendor firmware and compatibility guidance for the host equipment to ensure stable 40G links in data center and carrier environments.
