## Summary description

Compatible Huawei QSFP transceiver BlueOptics QSFP-40G-iSM4 supporting 40GBASE-PLR4L links over singlemode fiber. Uses MPO/MTP connector, operates at 1310 nm wavelength and supports up to 2 km reach. Designed for data center and carrier-grade 40 Gbps uplinks and long-reach aggregation in standard 0–70°C environments.

## Long description

The BlueOptics QSFP-40G-iSM4 is a QSFP transceiver module compatible with Huawei equipment, designed for 40GBASE-PLR4L links over singlemode fiber. It uses an MPO/MTP interface, transmits at a wavelength of 1310 nm and supports link distances up to 2 km. The module is intended for data center uplinks, carrier-grade aggregation and other high-bandwidth interconnects operating in standard ambient temperatures from 0 to 70°C.
Advantages
The transceiver provides 40 Gbps aggregated throughput in a compact QSFP form factor and supports long-reach singlemode connections up to 2 km. Its MPO/MTP interface simplifies parallel-fiber connections and multi-fiber infrastructure migration. Designed to be compatible with common networking equipment, the module enables high-density port deployments and efficient use of fiber plant while maintaining industry-standard optical parameters for reliable link performance.
Suitable for
Data center 40 Gbps uplinks between switches and aggregation devices
Carrier and metro aggregation where singlemode long-reach links are required
High-density optical patch panels and MPO/MTP trunk cabling
Fiber upgrades from 10G to 40G using parallel singlemode infrastructure
When it may not be suitable
This transceiver is optimized for singlemode fiber with MPO/MTP connections and 40GBASE-PLR4L signaling; it is not suitable for multimode fiber networks or for direct-attach copper connections. It also requires network equipment that accepts QSFP modules and supports 40GBASE-PLR4L; it will not function in devices limited to other form factors or incompatible optical specifications.
Key specifications
Form factor: QSFP (Quad Small Form-factor Pluggable)
Data rate: 40 Gbps (aggregate)
Optical standard: 40GBASE-PLR4L
Fiber type: Singlemode fiber
Connector: MPO/MTP
Wavelength: 1310 nm
Maximum reach: up to 2 km over singlemode fiber
Operating temperature: 0 to 70 °C
How to use
Install the QSFP transceiver into a compatible QSFP port on your switch or optical line system following the equipment manufacturer’s hot‑swap and electrostatic discharge precautions. Connect an MPO/MTP trunk or cassette terminated with singlemode fibers to the module, ensuring correct fiber polarity and clean connector endfaces. Verify link status and negotiated speed through the host device management interface and perform optical power and end-to-end testing as part of commissioning.
What to consider before purchase
Confirm host device compatibility with QSFP form factor and 40GBASE-PLR4L optical specifications
Ensure your fiber infrastructure uses singlemode fiber and MPO/MTP terminations suitable for parallel optics
Check required operating temperature range and environmental conditions
Plan for fiber polarity, connector cleanliness and testing equipment for proper commissioning
Usage recommendations
Use clean MPO/MTP connectors and follow standard inspection procedures before insertion. For reliable long-reach links, validate end-to-end loss and power budget to confirm performance over the planned 2 km span. When integrating into mixed vendor environments, verify link compatibility from the host device and consider ordering a small quantity first for interoperability testing.
