What is a PLC Splitter?

A PLC (Planar Lightwave Circuit) splitter is a passive optical device that splits a single optical input into multiple outputs with precise power distribution. Unlike traditional FBT (Fused Biconic Taper) splitters, PLC splitters use semiconductor manufacturing techniques to create waveguide circuits on a silica substrate.

This technology enables PLC splitters to achieve:
• Uniform power splitting across all output ports
• Low insertion loss (typically 0.3-0.5dB for 1x32)
• Excellent wavelength independence (1260-1650nm)
• Compact size and high reliability
• Consistent performance across wide temperature ranges

PLC splitters are the preferred choice for high-port-count applications in modern PON networks, where precise power budgeting and long-term stability are critical.

FAQ

Q1: What is the difference between PLC splitter and FBT splitter?

A: PLC splitters use planar lightwave circuit technology with precise waveguide patterns on a silica substrate, offering better uniformity, lower insertion loss, and wavelength independence. FBT splitters use fused biconic taper technology, which is more cost-effective for low port counts (1x2, 1x4) but has higher loss and poorer uniformity for high port counts.

Q2: What splitting ratios are available for PLC splitters?

A: Opelink offers standard splitting ratios of 1x2, 1x4, 1x8, 1x16, 1x32, and 1x64. We also provide 2xN configurations (2x4, 2x8, 2x16, 2x32) for applications requiring dual inputs. Custom ratios can be manufactured upon request.

Q3: What is the typical insertion loss of a 1x32 PLC splitter?

A: Opelink's 1x32 PLC splitters feature typical insertion loss of ≤17.0dB, with premium versions achieving ≤16.5dB. This includes the theoretical splitting loss of 15.05dB (10×log32) plus excess loss of approximately 1-2dB.

Q4: Can PLC splitters be used for both 1310nm and 1550nm wavelengths?

A: Yes, Opelink PLC splitters operate across a wide wavelength range of 1260-1650nm, making them suitable for both 1310nm and 1550nm applications, as well as CWDM and DWDM systems. The insertion loss variation across this range is typically less than 0.5dB.

Q5: Do you offer OEM/ODM services for PLC splitters?

A: Yes, we provide comprehensive OEM/ODM services including custom logos, packaging, fiber lengths, connector types, and labeling. Our engineering team can also design custom splitter configurations for specific applications. Minimum order quantities apply for custom products.
