Network QSFP Transceiver BlueOptics BO25K13630D 40GBASE-ER4L 30 km

BlueOptics BO25K13630D is a QSFP 40GBASE-ER4L transceiver module designed for long-reach 40 Gbps links. The module delivers quad-lane 40 G connectivity in a compact QSFP form factor and supports transmission distances up to 30 km over single-mode fiber. It is intended for use in data centers and carrier networks that require extended-reach uplinks, aggregation and cross-connect links between sites.

Advantages

The transceiver offers reliable 40G performance with low power consumption and a compact QSFP interface that simplifies port density and hot-pluggability. Its long-reach capability up to 30 km enables consolidation of network segments and extension of high-speed links between buildings or sites without additional intermediate equipment. The module supports standard 40GBASE-ER4L signaling for broad compatibility with switches and routers that accept QSFP 40G optics.

Suitable for

• Long-reach uplinks in data centers
• Inter-site 40 G connections across metropolitan or campus networks
• Aggregation and cross-connect links requiring 30 km reach
• Carrier and service provider backbone segments

Key specifications

• Interface: QSFP form factor, quad-lane 40 G
• Standard: 40GBASE-ER4L
• Maximum reach: up to 30 km over single-mode fiber
• Fiber type: single-mode fiber (SMF)
• Transmission: 4 × 10 G lanes aggregated to 40 G
• Hot-pluggable design for easy field replacement

How to use

Install the QSFP transceiver into a compatible QSFP port on a switch or router while the port is powered and supported by the host device. Connect single-mode fiber using appropriate LC or MPO connectors as required by the host and cabling infrastructure, taking care to observe proper fiber handling and connector cleanliness. Configure the host interface for 40G operation if necessary and verify link status and diagnostics through the network device management interface.

Recommendations

Ensure fiber endfaces are clean and use compatible single-mode patch cords rated for long-reach links. Verify that the host device firmware supports 40GBASE-ER4L optics and monitor transceiver diagnostics (if available) to confirm optical power and temperature are within expected ranges.
