Fused Coupler, Single Window, Low Loss, C or L Band
FFCH Series
Key Features
• Broad wavelength coverage over multiple bands
• High-power handling
• Wide range of standard parts readily available
• Proven reliability
Applications
• Passive optical networks
• CATV
• Network expansion
• Fixed attenuation (select
configuration option 0)
The single-window fused coupler splits or combines light with high performance
over a wide bandwidth. These components are manufactured using a highly
automated process to achieve consistent quality and reliability.
These high-performance standard parts are available with a variety of tap ratios,
operating wavelengths, and housing and connector options, and can therefore be
specified in a wide range of applications, enabling rapid design cycles and new
project builds. Reliability is assured through qualification to Telcordia GR-1221.

Tap ratio
≤
five percent, the Insertion Loss including WDL, PDL and TDL; Tap ratio > five percent, the Insertion Loss including WDL and PDL, not including TDL.
In 2x2 couplers with a coupling ratio of 20 percent or lower, insertion loss is not specified for launch through second input port (P4).
Change in insertion loss over the operating wavelength range.
Change in insertion loss over all input polarization states.
Change in insertion loss from –5 to 75°C. Guaranteed by design when tap ratio higher than five percent.

1. For wavelength within ±5 nm of the specified range performance will be maintained for signal path insertion loss, PDL, TDL, directivity and return loss. The only parameters to increase will be tap
insertion loss and WDL. Maximum values of increase are:
Tap ratio = 1%, maximum tap insertion loss and WDL increase = 0.1 dB.
Tap ratio = 2 to 9%, maximum tap insertion loss and WDL increase = 0.07 dB.
Tap ratio = 10 to 50%, maximum tap insertion loss and WDL increase = 0.05 dB.
2. For 1x2 and 2x2 configurations.
3. TDL is specified from –5 to 75°C.
