Description
Planar lightwave circuit (PLC) optical fiber splitter is a type of optical power management device that is fabricated using silica optical waveguide technology to distribute optical signals from Central Office (CO) to multiple premise locations. Yingda full arrange PLC Splitter in balanced split ratio or unbalanced split ratio, which feature small size, high reliability, wide operating wavelength range and good channel-to-channel uniformity.
- Balanced splitter mainly are splitter 1*2, 1*4, 1*8, 1*16, 1*32, 1*64, 1*128, 2*2, 2*4, 2*8, 2*16, 2*32, 2*64, etc.
- Unbalanced splitter mainly are splitter 1*3, 1*5, 1*6, 1*9, 1*12, etc.
If unbalanced splitter made by fused coupler 1×2, it can be any rations like: 1/99, 110/90, 15/85, 20/80, 25/75, 30/70, 35/65, 40/60, 45/55, 50/50. But if use PLC chip, due to the annual quantity is not so big as the plc splitter, so 1*3 unbalanced fiber optic plc splitter we can make now is 80/20, 70/30, 60/40, 40/60.
Fiber Optic Splitter 1×3 Unbalanced Features
- Low insertion loss and high return loss
- PDL automatic screening system(Ultra low PDL is available)
- High reliability and stability
- Connector can up to grade B
- 100% 3D tested by Daisi and Sumix
- High-low temperature cycle test
- 100% test before delivery
- FTTH Cabling solution could be design
1×3 Unbalanced Optical Splitter Application
Passive optical network (such as EPON, GPON, BPON, FTTX, FTTH, etc.), and supports multiple users to share a single PON interface.
