Optical QSFP Transceiver BlueOptics BO25K13630D 40GBASE-ER4L 30 km

BlueOptics BO25K13630D is a QSFP optical transceiver engineered for 40GBASE-ER4L connectivity over single-mode fiber with a reach of up to 30 km. The module delivers 40 Gbps aggregate throughput using four 10 G lanes and is intended for high-speed data centers, campus interconnects, and metro networks where long-reach 40 G links are required. The transceiver fits standard QSFP form factor slots and supports reliable long-distance transport between sites while simplifying uplink and aggregation upgrades.

Advantages

The transceiver offers a compact QSFP form factor and supports four-lane 10 G operation to provide full 40 G bandwidth with low power consumption. Its single-mode fiber design and long-reach capability up to 30 km reduce the need for intermediate regeneration equipment. The module is compatible with typical QSFP ports and supports straightforward installation, enabling predictable performance for long-haul 40 G links in data center and metro environments.

Suitable for

• Long-distance 40 G links between data centers and campus buildings
• Metro network aggregation and transport over single-mode fiber
• High-bandwidth uplinks in core switching and edge routing equipment
• Network upgrades requiring 40GBASE-ER4L compliant transceivers

Key specifications

• Form factor: QSFP (Quad Small Form-factor Pluggable)
• Data rate: 40 Gbps aggregate (4 × 10 G lanes)
• Transmission medium: single-mode fiber
• Maximum reach: up to 30 km
• Protocol/standard: 40GBASE-ER4L
• Wavelength: four-lane optical channels compatible with long-reach single-mode operation
• Typical use: long-reach aggregation and interconnect links

How to use

Install the BlueOptics QSFP transceiver into a compatible QSFP port on a switch, router, or media converter following the host device manufacturer's hot-plug guidelines. Connect single-mode fiber with appropriate LC connectors or breakout assemblies for 4×10 G lanes, verify link LEDs and host diagnostics, and configure the network interface as required by your equipment. Observe ESD precautions when handling the module and ensure fiber connectors are clean before mating to avoid signal degradation.

Recommendations

For reliable long-distance operation, use certified single-mode fiber with suitable link margin, maintain clean connector endfaces, and verify compatibility with the host device's transceiver support list. Monitor optical power and link status via host diagnostics and allow for additional margin when planning fiber spans close to the maximum 30 km reach.
