AS Fiber Optical Coupler – Multiple Coupling Ratios for Fiber Networks
When working with fiber optic networks, different applications require different levels of optical signal distribution. AS Fiber Optical Coupler is available in multiple coupling ratios so that network installers, ISPs and fiber technicians can select the required ratio according to their network requirement.
The available ratios are 50:50, 60:40, 70:30, 75:25, 85:15, 90:10 and 95:05.
The main advantage of keeping multiple ratios in one product range is flexibility. A 50:50 fiber coupler can be used where approximately equal optical power distribution is required, while ratios such as 90:10 or 95:05 can be used where a smaller portion of optical power needs to be coupled or tapped.
Optical couplers are commonly available in different coupling ratios, and the insertion loss characteristics vary according to the selected ratio
What is an AS Fiber Optical Coupler?
An AS Fiber Optical Coupler is a passive optical component used to divide, combine or tap optical power between fiber paths according to a specified coupling ratio.
For example, a 50:50 coupler is intended for approximately equal power distribution between its two output paths, while a 90:10 coupler provides a substantially different distribution between the two paths.
This makes different coupling ratios useful for different fiber network designs and optical signal distribution requirements.
Important: Actual insertion loss, operating wavelength, fiber type, connector type and package specifications should be verified from the product datasheet for the particular AS Fiber Coupler supplied.
Which AS Fiber Coupler Ratios Are Available?
You can select the required ratio from the following options:
1. AS Fiber Coupler 50:50
The 50:50 Fiber Optical Coupler provides an approximately equal coupling ratio between the two output paths.
Price: ₹95
It can be selected when the application requires near-equal optical power distribution.
2. AS Fiber Coupler 60:40
The 60:40 Fiber Optical Coupler provides an unequal optical power distribution between the two output paths.
Price: ₹95
This ratio can be selected when the network design requires a controlled 60/40 power distribution.
3. AS Fiber Coupler 70:30
The 70:30 Fiber Optical Coupler provides a 70/30 coupling distribution.
Price: ₹95
It can be useful for applications where one optical path requires a larger share of the coupled signal than the other.
4. AS Fiber Coupler 75:25
The 75:25 Fiber Optical Coupler provides a 75/25 coupling ratio.
Price: ₹95
This option is suitable for applications requiring a more unequal optical power distribution.
5. AS Fiber Coupler 85:15
The 85:15 Fiber Optical Coupler provides an 85/15 coupling ratio.
Price: ₹95
This type of ratio can be useful where the main optical path requires a larger portion while a smaller portion is coupled to another path.
6. AS Fiber Coupler 90:10
The 90:10 Fiber Optical Coupler provides a 90/10 coupling ratio.
Price: ₹95
It is useful for applications requiring a high-power main path with a smaller optical tap.
7. AS Fiber Coupler 95:05
The 95:05 Fiber Optical Coupler provides a 95/05 coupling ratio.
Price: ₹95
This ratio is particularly useful where only a small portion of the optical signal needs to be tapped while keeping most of the signal on the primary path.
Different coupler ratios such as 90/10 and 95/5 are commonly specified with significantly different insertion-loss values on their primary and secondary ports, so the exact datasheet should be checked before designing a link around a particular ratio. check Saplliter

Which Fiber Coupler Ratio Should You Choose?
The correct ratio depends on your optical network design.
| Ratio | General Distribution |
|---|---|
| 50:50 | Approximately equal distribution |
| 60:40 | Moderate unequal distribution |
| 70:30 | Higher primary-side distribution |
| 75:25 | Higher primary-side distribution |
| 85:15 | High primary-side / low secondary-side |
| 90:10 | High primary-side / small tap |
| 95:05 | Very high primary-side / small tap |
These ratios describe the intended coupling relationship; they should not be treated as guaranteed measured optical power percentages without the manufacturer’s test specifications.
Where Can AS Fiber Optical Coupler Be Used?
The AS Fiber Optical Coupler can be considered for a range of fiber-optic applications, including:
- FTTH networks
- FTTx networks
- ISP fiber networks
- Telecom networks
- PON-related applications
- Optical signal monitoring

- Fiber communication systems
- Network testing applications
- Fiber optic equipment
Fiber couplers are used across telecommunications, CATV, LAN and network-monitoring applications, depending on their construction and specifications.
How Does a Fiber Optical Coupler Work?
A fiber optical coupler distributes optical power between optical paths according to its specified coupling ratio.
For example:
50:50:
The optical power is divided approximately equally between the two paths.
70:30:
One path receives the larger portion and the other receives the smaller portion.
90:10:
Most of the optical power remains on the primary path while a smaller portion is coupled to the secondary path.
95:05:
The secondary path receives only a small portion of the optical power.
The actual optical output depends on the coupler design, wavelength, insertion loss and other optical parameters.

Is 50:50 Better Than 90:10 Fiber Coupler?
Neither ratio is universally better. The correct choice depends on the requirement of the optical network.
A 50:50 Fiber Coupler is intended for approximately equal distribution, whereas a 90:10 Fiber Coupler is intended for a much more unequal distribution.
Similarly, 95:05 is useful when only a small portion of the optical signal needs to be coupled.
Therefore, select the coupling ratio according to the required optical power distribution rather than simply choosing one ratio for every installation.
