The hot-swappable Input/Output (I/O) Cards provide excellent in-service expansion capabilities in
convenient sets of 20 ports per card, allowing re-configuration without interrupting signal processing. The
TLX640 will support up to 32 Input/Output Cards.
Each I/O card consists of one Transmit (T) and one Receive (R) optic per port. I/O Cards are available
with LC-type fiber connectors and can be assembled with Single-mode or Multi-mode optics (SFP+).
Each individual TLX640 I/O Card numbers the ports 1 through 20. An LED located on each card indi-
cates when power is applied to that card.
