BlueOptics QSFP Transceiver QSFP-40G-eSM4-BO for 40GBASE-PLR4, MPO/MTP, Singlemode 1310nm, 10 km, 0–70°C

BlueOptics QSFP Transceiver QSFP-40G-eSM4-BO is a compatible QSFP module that provides 40GBASE-PLR4 connectivity over singlemode fiber using an MPO/MTP interface. Operating at a central wavelength of 1310 nm, this transceiver supports link distances up to 10 km and is designed to function in environments with ambient temperatures from 0°C to 70°C. The module targets core and aggregation network segments, data center interconnects and long-reach metro links where 40 Gbit/s lanes and compact QSFP form factor are required.

Advantages

This BlueOptics QSFP transceiver delivers 40GBASE-PLR4 performance in a hot-pluggable QSFP package compatible with MPO/MTP multi-fiber connectors, enabling dense, high-speed uplinks and interconnects. Its singlemode 1310 nm optics and 10 km reach make it suitable for medium-distance fiber runs while the industrial operating temperature range supports deployment in standard telecom racks and data center environments. The module is designed for electrical and optical interoperability with equipment accepting QSFP form-factor transceivers, allowing flexible network upgrades without changing existing cabling infrastructure.

Suitable for

• 40 Gbit/s backbone links in data centers and aggregation nodes
• Metro and campus long-reach interconnects up to 10 km
• High-density MPO/MTP fiber installations requiring QSFP optics
• Network upgrades where 1310 nm singlemode optics are specified

When it may not be suitable

This transceiver is intended for singlemode fiber at 1310 nm and is not suitable for multimode fiber infrastructures or for applications requiring wavelengths other than 1310 nm. It is optimized for 40GBASE-PLR4 use; networks requiring different Ethernet standards or lower-cost short-reach optics (e.g., SR variants) should consider alternative transceivers.

How to use

Install the QSFP transceiver into a compatible QSFP port on your switch, router or optical transport device while the host is powered on or off according to the equipment’s hot-plug guidance. Connect the MPO/MTP-terminated singlemode fiber cable to the transceiver’s connector, ensuring correct keying and polarity. After insertion and cable connection, verify the link status via the host device management interface and monitor optical power and error counters to confirm proper operation. Follow your equipment vendor’s instructions for enabling 40GBASE-PLR4 ports and any required interface configuration.

What to consider before purchase

• Confirm your hardware accepts QSFP transceivers and supports 40GBASE-PLR4 optics.
• Ensure your fiber plant uses singlemode fiber with MPO/MTP connectors and appropriate polarity.
• Check link distance requirements to verify the 10 km reach is sufficient.
• Verify operating temperature range is compatible with your deployment environment.

Usage recommendations

Use factory-tested MPO/MTP singlemode patchcords and maintain correct polarity when connecting QSFP-40G-eSM4-BO. Monitor optical power levels after installation and keep the transceiver clean and protected from dust when not in use. For interoperability, validate the module with your specific switch or transport platform in a lab environment before widespread deployment.
