## Summary description

Compatible BlueOptics QSFP transceiver QSFP-40G-eSM4-BO provides 40GBASE-PLR4 connectivity via MPO/MTP interface for singlemode fiber at 1310 nm. Designed for up to 10 km reach and operating temperature range 0°C to +70°C, it supports high-speed data links in core and aggregation networks, data centers, and long-reach metro applications.

## Long description

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.
Key specifications
 Form factor: QSFP (Quad Small Form-factor Pluggable)
 Data rate: 40 Gbit/s (40GBASE-PLR4)
 Optical interface: MPO/MTP multi-fiber connector
 Fiber type: Singlemode fiber
 Wavelength: 1310 nm
 Maximum link length: up to 10 km
 Operating temperature range: 0°C to 70°C
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.
