Is this module compatible with NetScout equipment?

Yes, the AddOn 321-2133-AO is fully compatible with NetScout 321-2133 QSFP28 slots, meeting or exceeding OEM specifications. It features QSFP28 form factor with 100GBase-SR4 technology for plug-and-play integration in NetScout switches and routers.

What fiber type does it use?

It requires OM4 multi-mode fiber (MMF) with MPO connector for 100GBase-SR4 operation at 850nm. This supports up to 100m distance, making it suitable for intra-datacenter links where MMF infrastructure is standard.

What speed and interface does it provide?

Offers 100Gbps full duplex Ethernet speed via QSFP28 single port interface. The parallel optics design uses four 25Gbps lanes for aggregate 100G performance in datacenter environments.

Does it support digital diagnostics?

Yes, the module includes DOM support for monitoring parameters like temperature, voltage, and optical power. This aids in proactive network management for 100GBase-SR4 links over OM4 MMF.

Yes, the AddOn 321-2133-AO is TAA compliant with USA/UK country of origin, suitable for government and enterprise procurement requiring trade agreement adherence alongside 100G QSFP28 functionality.
