New high-temperature coating for single- and multimode fibers
j-fiber GmbH offers an improved high-temperature coating for its singlemode and multimode fiber portfolio. The new coating system benefits from:
- superior microbending performance (Table 1)
- improved coating strippability (Table 2)
- low loss at low and high temperatures (0,05 dB/km, Fig. 1)
- low loss after coloring (Fig. 2)
The upper use temperature is +150°C long-term and 200°C short-term, thereby maintaining the excellent high-temperature stability of the former coating system.
The new high-temperature coating complies with current Rohs and Reach regulations.

|Typ. Attenuation Increase at -45°C||Typ. Attenuation Increase at -65°C|
|New Coating System||< 0,4 dB/km||< 1,5 dB/km|
|Former Coating System||< 1,5 dB/km||< 3 dB/km|

|Typical Average Strip Force (N)||Typical Peak Strip Force (N)|
|New Coating System||< 2,5||< 4|
|Former Coating System||< 3,5||< 5|
