QSFP transceiver BlueOptics BO25K13630D 40GBASE-ER4L 30 km 1310 nm

BlueOptics BO25K13630D is a QSFP transceiver engineered for 40GBASE-ER4L links over single-mode fiber at a wavelength of 1310 nm, with a nominal reach of up to 30 km. The module fits QSFP ports and provides 40 Gbps aggregated throughput, enabling long-reach metro and campus backbone connections. It is intended for use in network switches, routers and optics-capable servers where reliable long-distance fiber connectivity is required.

Advantages

The transceiver supports 40 Gbps operation with an extended-reach ER4L optical design optimized for long single-mode links. Its QSFP form factor allows high port density and straightforward hot-pluggable replacement in compatible network equipment. Operating at 1310 nm and specified for up to 30 km, it reduces the need for intermediate regeneration and is suitable for direct fiber runs between sites. The module is designed for stable performance in carrier-class network environments and for integration into existing fiber infrastructures.

Suitable for

• Long-reach metro and campus backbone fiber links
• Upgrading QSFP-enabled switches and routers to 40 Gbps
• Inter-site connectivity between data centers or aggregation points
• Single-mode fiber runs requiring up to 30 km reach

Key specifications

• Data rate: 40 Gbps aggregate
• Optical type: 40GBASE-ER4L
• Wavelength: 1310 nm
• Maximum reach: up to 30 km over single-mode fiber
• Form factor: QSFP (Quad Small Form-factor Pluggable)
• Connector type: compatible with single-mode fiber interfaces

How to use

Install the BlueOptics QSFP transceiver into a compatible QSFP port on a switch, router or server following the equipment manufacturer’s hot-swap procedure. Connect single-mode fiber with appropriate LC/connector assemblies as required by your transceiver cage or adapter. Verify link status and configure the device port for 40G operation in the network equipment management interface. Ensure end-to-end fiber continuity and correct polarity before enabling production traffic.

Recommendations

For reliable performance, use single-mode fiber of appropriate grade and ensure connectors and patch panels are clean and inspected. Confirm compatibility with your host device’s optics support list and firmware, and test link budget and optical power levels when deploying near the 30 km range.
