QSFP-transceiver BlueOptics BO25K13630D 40GBASE-ER4L 30 km

The BlueOptics BO25K13630D QSFP transceiver is a compact, hot-pluggable optical module engineered for 40GBASE-ER4L applications with up to 30 km reach over single-mode fiber. It provides 40 Gbit/s aggregated transmission using four lanes and is intended for long-distance interconnects in data centers, carrier networks and backbone links where stable, high-speed optical connectivity is required.

Advantages

This QSFP module offers long-reach single-mode performance with support for 40GBASE-ER4L distances up to 30 km, a hot-pluggable form factor for maintenance-free swaps, and compatibility with standard QSFP ports for straightforward integration. The design focuses on reliable optical link quality for aggregation, distribution and backbone segments while maintaining low physical footprint and reduced cabling complexity.

Suitable for

• Long-distance 40 Gbit/s links between data centers or campus buildings
• Aggregation and backbone interconnects in carrier and service provider networks
• High-capacity uplinks in enterprise core and metro networks

Key specifications

• Interface: QSFP form factor supporting 40 Gbit/s aggregated transmission
• Standard: 40GBASE-ER4L
• Optical reach: up to 30 km on single-mode fiber
• Wavelength/lanes: multi-lane operation suitable for 4x10 Gbit/s channels
• Hot-pluggable: yes
• Application: long-reach fiber optic interconnects for data center and carrier environments

How to use

Install the transceiver into a compatible QSFP port on a switch, router or media converter while the device is powered according to the host equipment manual. Connect single-mode fiber using appropriate connectors and ensure correct polarity and fiber type. Monitor link status through the host device management interface and verify optical power levels and lane synchronization. For replacements or upgrades, remove the module by releasing the QSFP latch and insert the new transceiver until it seats fully.

Recommendations

Use single-mode fiber rated for long-distance transmission, maintain clean fiber endfaces, and verify that transceiver optical budgets meet link distance and margin requirements. Follow the host equipment guidance for supported transceiver types and firmware compatibility to ensure stable operation.
