Network QSFP Transceiver BlueOptics BO25K13630D 40GBASE‑ER4L 30 km

The BlueOptics BO25K13630D is a single‑module QSFP optical transceiver offering 40GBASE‑ER4L performance for long‑reach single‑mode fiber links up to 30 km. Designed for high‑speed Ethernet and data center interconnects, this QSFP module provides four optical channels aggregated to deliver 40 Gbps connectivity suitable for backbone connections, metro networks and equipment that requires optical 40G uplinks. The module is compatible with standard QSFP form factor interfaces and supports serial management and monitoring functions useful for network operations.

Advantages

The BlueOptics BO25K13630D delivers long‑reach transmission over single‑mode fiber with a compact QSFP footprint, enabling 40 Gbps density in switch and router ports while minimizing rack space. Built to support stable performance across extended distances, it reduces the need for intermediate regeneration in metro and campus backbones. Integrated monitoring features allow status checks for optical power and temperature, supporting predictable operation and easier troubleshooting.

Suitable for

• Data center interconnects and optical uplinks between aggregation switches
• Backbone and campus network links requiring 40 Gbps over single‑mode fiber
• Metro and regional network segments with spans up to 30 km
• Equipment requiring QSFP form‑factor 40G optical modules

Key specifications

• Topology: QSFP four‑channel optical transceiver providing aggregated 40 Gbps
• Standard: 40GBASE‑ER4L
• Reach: up to 30 km over single‑mode fiber
• Fiber type: single‑mode
• Wavelength: quad‑channel (DWDM/CWDM compatible envelope for long‑reach operation)
• Connector: QSFP compliant optical interface
• Monitoring: digital diagnostic monitoring (optical power, temperature, supply voltage)
• Form factor: QSFP (quad small form‑factor pluggable)

How to use

Insert the QSFP transceiver into a compatible QSFP slot on your switch, router or optical device while the host port is powered down if recommended by the equipment vendor. Connect single‑mode fiber patch cords to the optical interface following the correct polarity and connector types for your cabling plant. Verify that the host device recognizes the module and that link parameters such as speed and lane aggregation are configured for 40GBASE‑ER4L operation. Use the transceiver's digital monitoring features via the host management interface to confirm optical power levels and temperature after installation.

Recommendations

Use high‑quality single‑mode fiber and ensure end‑to‑end cleanliness of connectors to maintain link budget; verify compatibility with your switch or router vendor's supported transceiver list and follow their hot‑swap and ESD handling procedures to avoid damage. For spans near the 30 km limit, confirm optical power budget and margin considering connector and splice losses.
