Yingda manufactures various single mode fused biconical taper splitters with wavelengths of 1310nm, 1490nm, and 1550nm. Before placing an order, customers need to specify whether they require a single wavelength, dual wavelengths, or three wavelengths simultaneously. For multimode fiber, the typical wavelength is 850nm. Those single mode fiber coupler are widely used in fiber optic communication systems, CATV, FTTH, and fiber optic sensors.
The 1×2 Coupler 85/15 with SC/APC connectors is constructed with hytel 250um single-mode fiber and a 900um loose tube jacket. The input has white loose tube pigtail, and the output have red and blue pigtails sc. Since it’s an unbalanced cable splitter, to differentiate between the different splitting ratios, each optical fiber is equipped with a numerical identification ring. The loss of each unbalanced fiber splitter FBT is precisely controlled within a reasonable range, as follows:
| 1×2 Coupler Loss | Without Connector | WithConnector | |||
| Coupling Ratio | Loss (dB) | Loss (dB) | |||
| 15% | 85% | 8.44 | 0.91 | 9.3 | 1.2 |
Our company provides safe and reliable blister packaging boxes for each tapered fiber optic splitter, 2 splitters per box. Both splitters with and without connectors are packaged in the same type of blister boxes. For cost savings, PP bags can also be used for packaging, either one splitter per bag or 10 splitters per bag, etc. Please inform us of your specific packaging requirements in advance. Each product comes with independent packaging specifications and test reports.
