Transceiver BlueOptics ASTM-BO QSFP MPO/MTP 40GBASE-SR4 Multimode 4×850nm 150m 0–70°C

BlueOptics ASTM-BO is a QSFP optical transceiver module designed for short‑reach 40GBASE‑SR4 multimode links. The module uses an MPO/MTP interface and four 850 nm VCSEL channels to deliver aggregated 40 Gbit/s connectivity over multimode fiber. It supports transmission distances up to 150 meters on suitable OM3/OM4 fiber and is specified to operate reliably in environments with temperatures from 0°C to 70°C, making it suitable for data center and high‑speed aggregation applications.

Advantages

The QSFP MPO/MTP format provides a compact, hot‑pluggable solution for 40 Gbit/s short‑reach links, consolidating four optical lanes into a single duplex connector footprint. Four 850 nm VCSEL channels enable efficient multimode operation with low power consumption and predictable modal performance on OM3/OM4 fiber. The module’s industrial temperature rating and standardized SR4 optical characteristics ensure compatibility with common switches and aggregation devices that support 40GBASE‑SR4.

How to use

Install the QSFP transceiver into a compatible QSFP port on a switch, router or optical transceiver adapter until it latches securely. Connect an MPO/MTP multimode fiber assembly between the module and the corresponding MPO/MTP port or harness. Ensure the fiber type and patching (OM3/OM4) meet the specified multimode requirements and that channel lengths do not exceed the 150 m limit. Observe proper handling of the MPO/MTP connector to prevent contamination: keep dust caps on when idle and clean connector endfaces before mating. Verify link status on the host device and configure any necessary interface settings according to the equipment vendor’s instructions.

Recommendations

For reliable 40GBASE‑SR4 operation, use certified OM3 or OM4 multimode fiber and maintain channel lengths within the specified maximum. Clean MPO/MTP connectors before installation, follow fiber polarity and ribbon mapping best practices, and monitor link performance after deployment. When replacing or upgrading modules, confirm compatibility with the host device’s QSFP slot and firmware requirements.
