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

BlueOptics BO25K13630D is a QSFP transceiver module that implements the 40GBASE-ER4L standard for single-mode fiber (SMF). The module supports 40 Gbps aggregate bandwidth and is designed for long-reach optical links up to 30 km. Housed in a QSFP form factor, it provides four-lane 10 G serial optical interfaces aggregated to a single QSFP connector, enabling compatibility with equipment that accepts QSFP pluggable optics for high-density networking and data center interconnects.

Advantages

The BlueOptics BO25K13630D delivers long-distance 40 Gbps connectivity with a compact QSFP package, reducing port density constraints in racks and chassis. It supports single-mode fiber to achieve extended reach and stable transmission over metro or inter-data-center links. The module is compatible with typical QSFP interfaces, allowing straightforward hot-plug installation and interoperability with switches, routers and optical transport equipment that accept standard QSFP optics.

Suitable for

• Data center interconnects between sites up to 30 km apart
• Metro network links and aggregation rings
• 40G uplinks between switches and routers
• Optical transport equipment requiring 40GBASE-ER4L SMF modules

Key specifications

• Form factor: QSFP (Quad Small Form-factor Pluggable)
• Standard: 40GBASE-ER4L
• Data rate: 40 Gbps aggregate (four 10 G lanes)
• Fiber type: Single-mode fiber (SMF)
• Maximum reach: up to 30 km over SMF
• Interface: LC duplex/quad or QSFP optical connector (industry QSFP connector compatible)
• Hot-pluggable QSFP module for rack-mountable network equipment

How to use

Install the BO25K13630D into a compatible QSFP slot on the network device while the device is powered on or off, observing manufacturer guidelines for handling optical modules and electrostatic discharge precautions. Connect single-mode fiber patch cables between the module and remote optical equipment, ensuring correct connector types and polarity. Configure link settings on connected switches or routers as required for 40 Gbps operation; the module presents as a standard QSFP optical interface and usually requires no additional driver installation.

Recommendations

Verify optical budgets and link loss for your specific fiber route to ensure reliable operation at distances up to 30 km. Use quality single-mode fiber and LC-compatible connectors, maintain clean connector endfaces, and monitor link alarms or diagnostics provided by the host device to detect signal degradation. Follow the host equipment vendor’s compatibility notes when deploying third-party optical transceivers.
