To daisy chain host units:
On the upstream host, use optical ports O2 to O8) to connect to the
downstream host port O1
Use O2 to O8 to connect remotes
Do not connect O1 to remotes
Set the reference clock for the first host in the chain to
Internal
(Host A in
Set the reference clock to
Optical
for all downstream hosts (Host B, C and D in
To daisy chain remote units:
Connect O1 on the first daisy-chained remote to the host
Connect O2 on a daisy chained remote to O1 on the next downstream remote
The number of daisy-chained remotes depends on the optical delay of the system. See
Configuring Optical Delay Compensation
For example, in Figure 9-9, only Host B and C deliver both signal S1 and S2 to
remotes. With the additional optical port capacity provided by Host C, the system allows
for a total of 13 remotes connected directly to hosts carrying both signals.
To further increase the number of remotes, the example also shows how remotes can
be daisy chained. Remote A and B, and Remote D and E are daisy-chained remotes,
each connected to a single host optical port. The combined signal coming from the
host, is fed over one fiber to each remote in the chain.
