What is the maximum transmission distance?

The transceiver supports up to 100 meters of transmission distance over multi-mode fiber (MMF) at 850nm wavelength. This range covers typical datacenter floor layouts and inter-building connectivity, eliminating the need for expensive single-mode fiber infrastructure in most enterprise deployments.

Is this transceiver TAA compliant?

Yes, the 882251-B21-AO is fully TAA (Trade Agreements Act) compliant. This certification is essential for government agencies and regulated enterprises, ensuring the product meets federal procurement requirements and accelerating approval cycles for compliance-driven deployments.

Can this transceiver be installed without downtime?

Yes, the hot-swappable design enables live insertion and removal without service interruption. This capability is critical for mission-critical datacenter operations, allowing maintenance, upgrades, and replacements during normal business hours without scheduled downtime.

What monitoring capabilities does it provide?

The transceiver includes Digital Optical Monitoring (DOM) that provides real-time access to operational parameters including temperature, voltage, optical power, and bias current. This enables proactive network management, faster troubleshooting, and reduced mean-time-to-resolution for IT teams.

What connector type does this transceiver use?

The transceiver uses an MPO (Multi-fiber Push-On) connector in QSFP28 form factor. This standard connector type ensures compatibility with most modern datacenter switches and network equipment, simplifying deployment and reducing connector-related compatibility issues.
