this time. The OSC 0 IN is the add port for the OSC Tx and the OSC 0 OUT is the drop
port for the OSC Rx.

The SFP cage–This port provides OSC-band signal transmit and receive functionality
for a two-fiber, bidirectional optical link. The OSC signal provides Ethernet network
connectivity between the TCX1000-RDM20 nodes. The TCX1000-RDM20 includes
optical filters to support an OSC channel at either a 1511-nm or 1611-nm wavelength. The
SFP port uses the standard pin out as per the SFP MSA and accepts MSA-compliant
transceivers. The transceivers must be capable of supporting 100Base-FX. For more
information, see the list of supported SFP tranceivers in the
TCX Series Optical Transport
System Feature Guide

The cooling system in TCX1000-RDM20 consists of two fan modules. The fan modules
can be hot-swapped—you do not need to power off the TCX1000-RDM20 or disrupt the
TCX1000-RDM20 function to replace a fan module.
The TCX1000-RDM20 has two 650-W power supplies, either AC or DC depending on
your configuration. Only one power supply is required to power the device, while the
second power supply provides redundancy. When the TCX1000-RDM20 has both power
supplies installed and is connected to power, the device has full power redundancy. If a
power supply fails or is removed, the other power supply balances the electrical load
without interruption. Each power supply provides 12 VDC output with a standby voltage
of 12 VDC. The power supplies can be hot-swapped—you do not need to power off the
TCX1000-RDM20 or disrupt the TCX1000-RDM20 function to replace a power supply.
