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

BlueOptics BO25K13630D is a QSFP form-factor 40GBASE-ER4L optical transceiver designed for long-reach single-mode fiber links. The module delivers 40 Gbps aggregate bandwidth using 4×10G lanes and is compatible with standard QSFP ports. Intended for use in data centers, metro rings and carrier networks, it supports digital diagnostics and interoperability with compliant network equipment while providing an optical reach of up to 30 km over single-mode fiber.

Advantages

The transceiver offers high-density 4×10G lane operation in a compact QSFP package, enabling efficient use of port space and simplified cabling compared to multiple separate SFP+ modules. Support for digital diagnostics allows real-time monitoring of optical parameters such as transmit/receive power and temperature. Compliance with 40GBASE-ER4L optical specifications ensures predictable performance for long-reach single-mode links up to 30 km.

Suitable for

• Long-reach uplinks in data centers and campus networks
• Metro Ethernet and aggregation links
• Carrier and service provider backbone connections
• High-density switch and router QSFP ports

Key specifications

• Form factor: QSFP (Quad Small Form-factor Pluggable)
• Data rate: 40 Gbps aggregate via 4×10G lanes
• Optical standard: 40GBASE-ER4L
• Fiber type: single-mode fiber (SMF)
• Maximum reach: up to 30 km over single-mode fiber
• Monitoring: digital diagnostics monitoring (DOM)
• Wavelength/multiplexing: four 10G lanes (typical ER4L wavelength plan)
• Application: long-reach links for data center, metro and carrier networks

How to use

Install the module into a compatible QSFP port on a switch or router while the host device is powered according to the equipment vendor guidelines. Connect single-mode fiber patch cords with appropriate LC/LC or MTP/MPO adapters as required by the transceiver and the network design. Allow the host to complete link negotiation and check digital diagnostics to verify optical power levels and temperature. Follow your network equipment manual for interface configuration and speed/encoding settings to enable 40G operation.

Recommendations

Use quality single-mode fiber and properly rated patch cords to achieve the specified 30 km reach. Verify interoperability with the switch or router vendor and confirm that the host supports 40GBASE-ER4L QSFP modules. Regularly monitor DOM parameters to detect signal degradation and schedule maintenance if optical power or other diagnostics move outside expected ranges.
