Note: Per HP literature, the HP switches with SFP slots do not accept modules other than HP’s own SFPs. The HP switch identifies the manufacturer ID along with the part number and blocks operations to this port for non-HP interfaces. Other major SFP switch manufacturers do not indicate in their literature that such restrictions are imposed.Transition Networks SFP units fully comply with Multi-Sourcing Agreement (MSA). This compliance allows Transition Networks SFP modules to be used on other MSA-compliant SFP platforms without any problems.- Hot-Pluggable SFP Optical Transceiver With Duplex LC Connector- Class 1 Laser International Safety Standard IEC-60825 Compliant- Compatible with SFP Multi-Sourcing Agreement (MSA)TN-J4859C module:- Compliant with IEEE802.3z 1000BASE-LX
