The IANOS pre-terminated module is a "single" module which is pre-connectorised directly with a specific cable length. The pre-terminated system can be supplied as follows:
- With a module at both ends
- With a module at one end and a harness assembly at the other end
- With a module at one end and the other end loose for fusion splicing
Pre-terminated modules reduce the installation time considerably compared to spliced pigtails. Furthermore, they help data center operators achieve a near perfect length management of cables between racks. Generally, the pre-terminated module will be placed in a server rack and the other end will be spliced into a high-density LISA cross-connect rack. Pre-terminated systems can also be used to reduce the optical loss across a link by reducing the number of mated connector pairs, but care should be taken not to compromise flexibility if the infrastructure is upgraded to higher data rates at a later stage.
