Optical QSFP Transceiver BlueOptics BO25K13630D 40GBASE-ER4L 30 km 1310 nm

The BlueOptics BO25K13630D is a QSFP optical transceiver that supports 40GBASE-ER4L operation over single-mode fiber at 1310 nm with a reach of up to 30 km. Packaged in a QSFP form factor, this module is intended for high-density 40 Gbps links in data center and carrier environments where long-reach uplinks and metro connections are required. The module implements 40G transmission using four lanes and is suitable for integration into switches, routers and transponder equipment that accept QSFP optics.

Advantages

The transceiver delivers long-reach performance over single-mode fiber at 1310 nm while preserving the compact QSFP footprint for high port density. It supports 40 Gbps aggregate throughput and is engineered for stable operation in data center and carrier-grade networks. Passive QSFP compatibility and standardized electrical/optical interfaces simplify installation and interoperability with common networking hardware.

Suitable for

• Long-reach 40 G uplinks between data centers or aggregation sites
• Metro network links and regional fiber connections up to 30 km
• High-density switch and router ports requiring 40G QSFP optics
• Carrier and service provider backbone segments demanding 40G capacity

Key specifications

• Form factor: QSFP (Quad Small Form-factor Pluggable)
• Data rate: 40 Gbps aggregate (4x 10 G lanes)
• Wavelength: 1310 nm
• Maximum reach: up to 30 km over single-mode fiber
• Fiber type: single-mode fiber (SMF)
• Application: 40GBASE-ER4L long-reach Ethernet

How to use

Install the QSFP transceiver into a compatible QSFP port on the host device following the vendor's hot-plug procedures. Ensure the host device supports 40GBASE-ER4L optics and configure the port for 40 G operation if required. Connect single-mode fiber with appropriate connectors and verify link status using the host equipment's management interface. Observe proper ESD handling and keep protective caps on the optical interfaces when not connected.

Recommendations

For reliable 30 km links, use high-quality single-mode fiber and verify end-to-end loss budget before deployment. Confirm compatibility with the host device's optical interface list and perform link validation after installation. Maintain cleanliness of fiber connectors and monitor optical power and error statistics during initial operation.
