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

BlueOptics BO25K13630D is a QSFP optical transceiver designed for 40GBASE-ER4L links, delivering an aggregate data rate of 40 Gbps and supporting transmission distances up to 30 km over single-mode fiber. The module fits hot-pluggable QSFP form-factor slots used in high-density switches and routers, enabling long-reach 40 G connectivity for data center interconnects, campus backbones and metropolitan networks while maintaining a compact footprint.

Advantages

The transceiver provides long-distance 40 G transmission with low insertion effort thanks to its hot-pluggable QSFP design. It supports single-mode fiber for extended reach and is compatible with common 40GBASE-ER4L applications, offering stable optical performance and straightforward integration into existing optical links. The compact form factor helps conserve port density in switches and routers and simplifies maintenance and upgrades.

Suitable for

• Data center interconnects requiring 40 G long-reach links
• Campus backbone and aggregation links over single-mode fiber
• Metro network segments and carrier access links up to 30 km
• High-density switch and router ports where hot-pluggable modules are needed

Key specifications

• Interface: QSFP hot-pluggable transceiver
• Standard: 40GBASE-ER4L
• Aggregate data rate: 40 Gbps
• Optical reach: up to 30 km over single-mode fiber
• Fiber type: single-mode

How to use

Install the QSFP transceiver into a compatible QSFP slot on the network switch or router while the host device is powered on or following the vendor’s hot-swap guidance. Connect single-mode fiber using the appropriate connector and patching panel, observe transmitter and receiver orientations, and verify optical link status through the host device’s management interface. Monitor link indicators and diagnostic information to confirm proper operation.

Recommendations

Ensure compatibility with the host device’s QSFP port and confirm support for 40GBASE-ER4L before deployment. Use quality single-mode fiber and clean connectors to maintain optical performance. For links approaching the maximum reach, validate power budget and consider optical path loss, splicing, and connector losses when planning the installation.
