VS-44FO - Connecting the VS-44FO 9
5 Connecting the VS-44FO
This section describes how to connect the VS-44FO. The VS-44FO can switch one
of the four fiber optic inputs to any or all of the four fiber optic outputs, as the
example in Figure 3 shows.
Always switch off the power to each device before connecting it to your
VS-44FO. After connecting your VS-44FO, connect its power and then
switch on the power to each device.
The customer can replace any SFP module with a standard SFP
module but Kramer guarantees correct operation only with Kramer
supplied modules.
All SFP modules (up to four) must be of the same type: either MSA or
non-MSA.
Only modules Laser Class I acc. 21 CFR 1040 and Class 1 per IEC
60825-1 are allowed in this product.
The following optional SFP modules are tested and approved for use with the
VS-44FO:

SFP-IN/OUT-2KM – SFP Fiber Optic Module SM 2km 3G HD-SDI Tx/Rx

SFP-IN/OUT-30KM – SFP Fiber Optic Module SM 30km 3G HD-SDI Tx/Rx

SFP-IN/OUT-40KM – SFP Fiber Optic Module SM 40km 3G HD-SDI Tx/Rx
To connect the VS-44FO, do the following:
1. If SFP modules are preinstalled in your unit, go to step 4 below (and ignore
steps 1 to 3). If not, continue with step 2.
2. Insert an SFP module into each IN/OUT slot to be used (see Section 5.1 ).
3. Set the SFP Select button on the rear panel depending on the type of SFP
used. Press in for Non-MSA and release for MSA. The setting is saved after
powering the device ON.
4. Connect up to four fiber optic sources to the IN connectors (for example, 3G
HD-SDI video players connected to a Kramer 690T transmitter).
