Optical QSFP Transceiver BlueOptics BO25K13630D 40GBASE-ER4L 40Gbps 1310nm 30km

BlueOptics BO25K13630D is an optical QSFP transceiver designed for 40GBASE-ER4L operation over single-mode fiber. The module supports an aggregate data rate of 40 Gbps using ER4L optics with a transmit wavelength of 1310 nm and a maximum link reach of up to 30 km. It is intended for high-density 40G connectivity in switches and routers and for long-reach data center interconnects and metro links where ER4L compatibility is required.

Advantages

The transceiver provides long-reach single-mode performance with a compact QSFP form factor that supports 40 Gbps links while conserving rack port density. With a 1310 nm transmit wavelength and ER4L specification, it delivers predictable performance for links up to 30 km. The module is hot-swappable and compatible with standard QSFP interfaces, simplifying installation and replacement in live networks without service interruption.

Suitable for

• Data center interconnects between racks or sites over single-mode fiber
• Metro area networks requiring 40 Gbps long-reach links
• High-density switch and router uplinks supporting ER4L optics
• Service provider aggregation links and backbone segments

Key specifications

• Form factor: QSFP (Quad Small Form-factor Pluggable)
• Application: 40GBASE-ER4L
• Data rate: 40 Gbps aggregate
• Wavelength (transmit): 1310 nm
• Maximum link distance: up to 30 km over single-mode fiber
• Fiber type: single-mode fiber (SMF)
• Hot-pluggable: yes

How to use

Install the QSFP transceiver into a compatible QSFP port on a switch or router while the host device is powered on to take advantage of the hot-pluggable design. Connect single-mode fiber using appropriate LC or MPO adapters as required by the transceiver and the patching infrastructure. Verify link status on the host device and confirm that the port is set to operate at 40 Gbps with ER4L-compatible settings. Monitor optical power and signal diagnostics via host management interfaces if available.

Recommendations

Use clean, certified single-mode fiber and maintain proper end-face cleaning procedures to ensure optimal signal performance. Match the transceiver with ER4L-capable optics on the remote end and ensure fiber attenuation over the link does not exceed system budgets for 30 km operation. Avoid bending fiber sharply and follow manufacturer guidelines for insertion and removal to prevent damage to the module or port.
