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

BlueOptics BO25K13630D is a QSFP network transceiver designed to meet the 40GBASE-ER4L specification for long-reach optical links. Operating at a wavelength of 1310 nm, the module delivers 40 Gbps aggregate bandwidth over single-mode fiber for distances up to 30 km. The transceiver uses a hot-pluggable QSFP form factor that simplifies installation and replacement in switches, routers and optical equipment used in data center uplinks, metro and carrier networks.

Advantages

The transceiver supports 40GBASE-ER4L standard performance for reliable long-distance transmission, offering predictable signal characteristics at 1310 nm and an extended reach of up to 30 km over single-mode fiber. Its QSFP hot-pluggable form factor enables tool-free insertion and removal, reducing downtime for upgrades or swaps. The module is suitable for high-density equipment thanks to its compact design and enables aggregation of four 10 G lanes into a 40 G link, providing compatibility with infrastructure that uses parallel optics or lane aggregation.

Suitable for

• Data center uplinks and spine-to-leaf interconnects requiring long-reach links
• Metro and regional optical networks connecting sites up to 30 km apart
• Carrier access and aggregation where 40 Gbps capacity and single-mode fiber are used
• Equipment upgrades and hot-swappable transceiver replacement in switches and routers

Key specifications

• Form factor: QSFP (hot-pluggable)
• Standard: 40GBASE-ER4L
• Aggregate data rate: 40 Gbps
• Operating wavelength: 1310 nm
• Maximum link distance: up to 30 km over single-mode fiber
• Transmission medium: single-mode optical fiber
• Lane configuration: 4 lanes aggregated to 40 G

How to use

Before installation, verify that the target device supports QSFP transceivers and the 40GBASE-ER4L specification. Handle the transceiver by its housing and avoid touching optical interfaces; keep dust caps in place until connection. Insert the module into a compatible QSFP slot until it seats and locks; connect single-mode fiber cables with appropriate connectors to the optical ports. After insertion, confirm link negotiation and proper signal levels using the host equipment management interface or monitoring tools. For removal, power down the relevant port if required by the host, unlock the module and pull it straight out by the housing.

Recommendations

Use single-mode fiber with correct connector types and clean end-faces to achieve the specified 30 km reach. Operate within manufacturer-recommended temperature and power ranges, and perform optical power and BER checks during initial deployment and after any significant cable work. Keep spare dust caps and store unused transceivers in anti-static packaging to protect optical surfaces and electronic components.
