## Summary description

BlueOptics BO25K13630D is a QSFP 40GBASE-ER4L network transceiver designed for 40 Gbps optical links up to 30 km. It supports QSFP form factor connectivity for high-speed backbone, data center interconnects and long-reach aggregation. The module provides reliable single-mode fiber transmission and easy hot-plug installation to expand or upgrade network capacity.

## Long description

BlueOptics BO25K13630D is a QSFP 40GBASE-ER4L network transceiver engineered for 40 Gbps optical links over single-mode fiber up to 30 km. The QSFP form factor offers high-density port aggregation for backbone and data center interconnects, supporting long-reach aggregation and upgrades of existing 40G networks. The module is designed for hot-pluggable insertion into compatible QSFP ports, enabling quick expansion of network capacity with minimal downtime.
Advantages
The transceiver supports four independent transmit and receive lanes aggregated to deliver 40 Gbps throughput while maintaining low power consumption and compact QSFP packaging for high-density deployments. Its single-mode fiber operation and 30 km reach enable long-distance links between data centers or aggregation sites. The hot-pluggable design simplifies installation and replacement without powering down equipment, and standardized electrical and optical interfaces ensure interoperability with QSFP-capable switches and routers.
Suitable for
 Long-reach 40 Gbps links between data centers or campus buildings
 Backbone and aggregation layer connections in service provider networks
 High-density QSFP deployments in core switches and routers
 Upgrading existing 40G infrastructure for extended single-mode fiber runs
Key specifications
 Form factor: QSFP (Quad Small Form-factor Pluggable)
 Data rate: 40 Gbps aggregate (4 lanes)
 Optical standard: 40GBASE-ER4L
 Fiber type: single-mode fiber (SMF)
 Maximum link distance: up to 30 km over SMF
 Connector type: duplex LC (where applicable to ER4L wavelength breakout)
 Operating mode: hot-pluggable
How to use
Install the transceiver into a compatible QSFP port on a switch or router until it clicks into place. Connect single-mode fiber using the appropriate LC patch cords or breakout cables for ER4L wavelength lanes, ensuring correct polarity and clean connectors. After insertion, the host device typically recognizes the module and negotiates the 40G link automatically; verify link status and operational parameters via the host equipment management interface. For removal, follow normal hot-swap procedures recommended by the equipment manufacturer to avoid interrupting other ports.
Usage recommendations
 For reliable long-distance operation, use ITU-compliant single-mode fiber with appropriate attenuation budget and maintain clean connectors. Verify compatibility with the host equipment's QSFP interface and check optical power budgets for 30 km links. Follow the switch or router manufacturer's guidance for firmware and supported transceiver types to ensure interoperability.
