From my old Telecom days TX was on the left when facing upstream.

Now where's my walking stick. <br>

<div>There's probably a standard for it somewhere. The below

[AusNOG] TX/RX Conventions<br>
</font> </div>
<br>
Hi,<br>
<br>
I'm interested to understand which conventions/standards
(if any) are being used by operators to identify the
TX/RX in fibre patching panels/trays - in environments
like a meet me room or datacentre.<br>
<br>
For example, if someone is allocated ports 3&4 some
operators seem to use the "low" port as the TX, while
others use the low port as the RX. Also interested to
understand whether the convention specifies whether the
TX/RX is egress from the port or is specifying the
signal into the port.<br>
<br>
Thanks.<br>
Tom<br>
