Besides basic link characteristics such as SFP type, length of fiber link, wavelength and bit rate, all Black Box SFP transceivers feature extended diagnostics. This enables SFP transceivers to report information such as temperature, TX and RX power,
voltage and bias current.
Hot-swappable vs. hot-pluggable
On our SFP transceiver product pages you will find words like hot-swappable and hot-pluggable while reading the specifications. Why does an SFP transceiver have such a specification?
Hot-swappable means that the SFP transceiver can be removed and replaced by another transceiver without shutting down the system or without significant system downtime. If a new SFP transceiver can be added but cannot be removed without some kind of interference,
we call it hot-pluggable.
