Connection Information
SMALL FORM-FACTOR PLUGGABLE (SFP) OVERVIEW
Connections between the control
surface and processing core, all
Hydra2 network connections,
connections between I/O boxes
and routers and router-to-router
connections between cores, are all
made via SFP modules.
SFPs can be provided for RJ45 copper
connections, as well as singlemode or
multimode fibre on LC connectors. This
allows for each port’s connection type to
be chosen to suit cable-run distances and
the existing infrastructure. SFPs can be
changed easily on a port by port basis, as
and when required.
Note, only fibre SFPs can be used for
Summa surface to core connections.
If Calrec are supplying SFPs for your
installation, the correct quantity of SFPs
are supplied pre-fitted. The type of each
connection—copper, singlemode fibre or
multimode fibre—should be specified at
the time of order to ensure the correct
SFP types are supplied. Additional SFP
modules can be ordered if required. If a
system is to be connected to an existing
Hydra2 network, please discuss this with
your Calrec project leader, sales person
or local distributor to ensure that SFPs
are provided and ports provisioned for the
additional router to router connections.
SFPslotorientation
SFP modules plug into front panel slots
on router and modular I/O controller
cards and rear panel slots on fixed format
I/O boxes. The modules can be fitted or
removed whilst the system is powered up
and without removing or opening any card
or box casings.
Note the orientation of the SFP modules
as shown in the illustrations on this page.
Modules fitted in even numbered router
ports (left hand column) are fitted the
opposite way around to those in the
odd numbered router ports (right hand
column). Likewise for fixed format I/O
boxes, the primary SFP module is the
opposite way around to the secondary
SFP module. The modules are orientated
so that the release catch for the RJ45/LC
connector plugs, once inserted, are on the
outside edge.
For modular I/O box controller cards,
both SFP slots are orientated so that
the release catch on the cable/fibre
connector is on the right-hand side.
SFPlatchingandextraction
Calrec source SFP modules from various
manufacturers. All types used conform
to the same specification, however the
latching mechanisms can vary slightly.
The standard copper SFP and some fibre
SFPs, as shown in the photograph on
the previous page, have latch/extraction
handles. On insertion, the handles should
be set against the outer edge (the same
side as the release catch on the RJ45 /
LC connector plug that fits into the SFP)
to lock it into place and prevent accidental
removal if cables are pulled.
To remove this style of SFP, remove the
cable/fibre and slide the handle (copper)
or lift the handle out (fibre) to the inside
edge, as shown in the diagram to the right.
The module can then be removed by
pulling on the handle.

ROUTER CARD SFP ORIENTATION
FIXED FORMAT I/O BOX SFPS
• Router card shown with copper
SFPs fitted in ports 1-4,
singlemode fibre (button release)
in ports 5-8.
• I/O box shown with singlemode
fibre SFPs (button release) fitted.
• Both SFP types above have
a handle latching mechanism,
shown in the locked position. The
unit on the left is a singlemode
duplex LC fibre module. The unit
on the right is a copper RJ45
module.
