* Connector Options, Power Supply and NA Conversion Adaptor
Standard optical input connector of OE convertor uses FC type.
It can be changed to one of the types of SC, FSMA, F05, G-OCN or ST with additional fee.
Note that those optional receptacles do not come with dust protection caps shown in the Image 1.
Standard electrical output connector is BNC plug type shown in Image 2.
It can be changed to either type of SMA plug, SMA jack, or BNC jack with additional fee.Please specify the options when you order. We will make quote.

*** Image 1-2-4 : G-OCN is Originally designed by Graviton ***
G-OCN is a universal optical connector for 2.5 mm φ ferrule.
It works as a receptacle to fix one of the optical connectors, FC, SC, ST and F05 type which equips 2.5 mm φ ferrule on the top of the plug.
G-OCN is designed for convenience to start measuring by saving your time to assemble.
It is useful for short-term use to measure optical wave forms and so on.
However, it is not recommended to use it for long-term use applications such as general communication devices.
After an optical connector is plugged in, please avoid giving any pressure to the optical connector.
When plugging an optical connector, as the housing of the plug is not supported and only the ferrule is fixed, the connector and the ferrule could be damaged by any pressure.
The image shows an example of plugining in an SC connector to G-OCN. |
How to plug in/unplug an optical connector
* G-OCN has a sleeve in the center for 2.5 mm φ ferrule.
* Plug in the ferrule to the sleeve completely until it hits.
* Turn the knurled knob clockwise (direction A of the red arrow) to close the split sleeve to to fix the ferrule.
* To unplug the ferrule, turn the knurled knob counterclockwise (direction B of the red arrow) about hafl-way, after making sure the split sleeve is loosen, pull out the ferrule carefully.
* For printing : G-OCN
Note)
* When the ferrule is hard to pull out, after making sure the knurled knob is loosen, move it side to side carefully to lose, then unplug it.
* It is not recommended to use it for long-term use applications such as general communication devices.

* DC Power Supply Unit
The DC Power to the O/E converter, when the instrumental device which uses with the O/E convert has ± 15V output terminal of LEMO OS-4P type the supplied cable should be used.
If you do not have the power supply output which is compatible to the instrumental device, we can provide DC power supply.
Please contact us for quotation.
** Note : If you need to control the noise precisely, a dropper type power supply is strongly recommended.
If you do not care about the noise so much, a switching type DC power supply can be used.
Dropper type DC Power Supply [ Left ]:G1W-15 (COSEL) , [ Right ]:APS-1503W (Power Science Co., Ltd.)
As "G1W-15" has been discontinued, Graviton sales it as our stock lasts, then switches to "APS-1503W" without prior notice.
** Note : The power supply that we can sell is Japanese specification (input voltage AC100V) only.
* Auxiliary power cable
Some of the electronic instruments, used together with the O/E converter, does not have a DC power supply output
connector that can be fitted to the dedicated power cable. In such a case , using the auxiliary power cable, supply ± 15V
DC power to O/E converter from such as the external off-the-shell power supply.
[1] Connect an auxiliary power cable to the external power supply.
After checking the output of the power supply is off, connect the power supply and auxiliary power cable. Connect the
RED wire of auxiliary power cable to +15V, the BLACK wire to GND, and the BLUE wire to -15V.
The faulty wiring of a power supply cable causes failure to the O/E converter. Work carefully so as not to make
connection mistake.
[2] Connect a dedicated power cable and an auxiliary power cable.
[3] Plug in a dedicated power cable to the power connector of the O/E converter.
Before the power cable will be connected to the O/E converter, check that the power switch, shown in [4], is OFF.
[4] Turn ON the power supply unit and turn the switch of an O/E converter.
As an order of powering on, turn on the power supply, the first. As an order of powering off, the order of power off
does not matter.
** Note : If you need to control the noise precisely, a dropper type power supply is strongly recommended.
If you do not care about the noise so much, a switching type DC power supply can be used.
Supply range from your power supply: [Please refer to the following as a guideline]
Positive (+) voltage: +15V ±5% (±0.75V for +15V: range of +14.25 to +15.75V)
Negative (-) voltage: -15 V ±5% (±0.75 V for -15 V: range of -14.25 to -15.75 V)
* NA Conversion Adaptor
When delivering the light outputted from CD or DVD pickup, if a large core diameter fiber is placed directly on the top of the objective lens, the NA of the light may be too large to collect the light.
To solve this issue, using GC-3420 NA conversion adapter can guide the light within a range of NA 0.34 into the optical fiber with NA 0.2.
Please contact us for quotation.
