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

BlueOptics BO25K13630D is a QSFP form-factor optical transceiver that supports 40GBASE-ER4L links at 40 Gbps over single-mode fiber for distances up to 30 km. Designed for long-reach interconnects in data centres and campus networks, the module integrates four 10 Gbps lanes in a single QSFP housing to deliver high-density 40 Gbps connectivity. The transceiver is suitable for use in switches, routers and optical aggregation equipment where extended single-mode reach and reliable 40G transmission are required.

Advantages

The module provides long-reach 40 Gbps transmission over single-mode fiber up to 30 km while maintaining the compact QSFP footprint for high-density port deployments. Four parallel 10 Gbps lanes allow straightforward integration with 40GBASE-ER4L interfaces and reduce cabling complexity by carrying aggregated lanes in one pluggable unit. The transceiver is engineered for compatibility with industry-standard QSFP ports, offering low power consumption and stable optical performance across the operating temperature range.

Suitable for

• Inter-rack and inter-building links in data centres and campuses
• 40G aggregation and uplink ports on switches and routers
• Optical transport where single-mode long-reach connectivity is required
• Network upgrades requiring compact, high-density 40 Gbps modules

Key specifications

• Form factor: QSFP (Quad Small Form-factor Pluggable)
• Data rate: 40 Gbps (4 × 10 Gbps lanes)
• Standard: 40GBASE-ER4L
• Optical fiber type: single-mode fiber (SMF)
• Maximum link length: up to 30 km over single-mode fiber
• Wavelength: four parallel lanes in the ER4L wavelength allocation
• Connector type: LC (typical for single-mode duplex connections via MPO/MTP breakout)
• Power consumption: low-power QSFP class (typical values depend on system implementation)

How to use

Install the QSFP module into a compatible QSFP port on a switch, router or transponder following the host device manufacturer's instructions. Use single-mode fiber cabling and appropriate LC-terminated or MPO/MTP breakout assemblies to connect the module to the remote device. Ensure that transceiver settings on both ends match the 40GBASE-ER4L mode and verify link status using the network equipment management interface. Observe ESD precautions when handling the module and remove protective caps from optical connectors before insertion.

Recommendations

For reliable long-reach performance, use quality single-mode fiber with appropriate attenuation margins and ensure connector cleanliness. Confirm compatibility with the host equipment's QSFP port and firmware, and verify optical power budget for 30 km links including patch panel and connector losses. Store spare modules in original packaging and avoid exposure to moisture or extreme temperatures.
