## Summary description

The BlueOptics QSFP transceiver BO25K13630D is a 40GBASE-ER4L optical module designed for 40 Gbps links up to 30 km. It fits QSFP form-factor ports and supports long-reach fiber connections for data centers, metro and campus networks. Use it to extend 40G uplinks between switches, routers and aggregation equipment over single-mode fiber for reliable high-speed transport.

## Long description

The BlueOptics QSFP transceiver BO25K13630D 40GBASE-ER4L is an optical module for 40 Gbps links with a reach of up to 30 km. Designed for the QSFP form factor, this transceiver supports long-reach single-mode fiber connections and is suitable for data center uplinks, metro and campus interconnects. It provides a standardized electrical and optical interface for insertion into QSFP ports on switches, routers and aggregation devices, enabling high-throughput transport over extended distances.
Advantages
This 40GBASE-ER4L transceiver offers high bandwidth and stable performance over long distances, combining QSFP compatibility with optical components optimized for 30 km single-mode links. Its form factor allows easy hot-swap installation in equipment with QSFP ports, while compliance with the 40GBASE-ER4L specification ensures interoperability with standard networking hardware. The module is suitable for reducing the number of parallel links by aggregating 40 Gbps traffic and for maintaining signal integrity across metro spans.
Suitable for
Extending 40G uplinks between switches and routers over single-mode fiber
Long-reach connections in data centers and campus networks
Metro network trunks and aggregation links up to 30 km
High-bandwidth interconnects for backbone and edge equipment
Key specifications
Data rate: 40 Gbps
Standard: 40GBASE-ER4L
Reach: up to 30 km over single-mode fiber
Form factor: QSFP
Optical interface: long-reach single-mode fiber
Application: uplinks, aggregation and long-distance interconnects
How to use
Install the transceiver into an available QSFP port on a compatible switch or router, following the host device manufacturer’s hot-swap and ESD handling procedures. Connect single-mode fiber using appropriate LC or MPO adapters as required by the system cabling. Configure link settings on network equipment to enable 40 Gbps operation and verify the optical link status through device management interfaces or diagnostics. Monitor signal quality and error counters during initial commissioning to confirm stable operation.
Usage recommendations
Use certified single-mode fiber rated for 30 km spans and maintain clean connector endfaces to preserve optical performance. Ensure the host equipment supports 40GBASE-ER4L optics and QSFP transceivers. For installations spanning multiple patches or intermediate connections, account for additional insertion loss and plan for appropriate optical power margins.
