BlueOptics QSFP-transceiver 4TC7A85336-BO (40GBASE-SR4, MPO/MTP, multimode, 4×850nm, 150m, 0–70°C)

BlueOptics QSFP Transceiver 4TC7A85336-BO is a pluggable 40GBASE-SR4 multimode transceiver designed for short-reach 40 Gb/s links in data center and enterprise network environments. The module uses an MPO/MTP interface and four parallel 850 nm lanes to provide aggregated 40 Gb/s transmission over multimode fiber up to 150 meters. Engineered for switch-to-switch and high-density 40G deployments, this transceiver supports an operating temperature range of 0 °C to 70 °C and is compatible with standard QSFP cages and ports.

Advantages

The transceiver provides compact, hot-swappable QSFP form factor convenience for easy installation and replacement without powering down equipment. Using an MPO/MTP connector and parallel optics minimizes cabling complexity in high-density patching panels. Designed for multimode fiber and 850 nm VCSEL lanes, the module enables cost-effective short-reach 40G links while maintaining industry-standard optical parameters. The operating temperature range and standardized form factor make it suitable for typical data center rack environments and professional networking gear.

How to use

Insert the QSFP transceiver into a compatible QSFP port on your switch or network device until it seats securely and the latch clicks. Connect an MPO/MTP multimode fiber patch cable between the transceiver and the remote module or patch panel, ensuring correct fiber polarity and that the cable supports the specified multimode fiber type and distance. Verify link status through your switch management interface or status LEDs to confirm proper operation. For hot-swap replacements, remove the module by releasing the latch and pull it straight out before inserting the new unit.

Recommendations

Use OM3 or OM4 multimode fiber to achieve the specified reach and performance; OM4 is recommended for higher margin and future-proofing. Keep optical connectors clean and inspect them prior to connection using appropriate fiber cleaning tools. Avoid bending multimode fiber beyond the minimum bend radius and ensure patch panels and cable runs follow data center cabling standards for optimal signal integrity.
