FIELD: optical engineering.
SUBSTANCE: dispersion-compensated fiber when being reeled upon small spool does not result to losses and it has stable temperature characteristic. For fibers with compensation of dispersion within wave range of 1,53 50 1,63 micrometers, bend losses with diameter of reeling of 20 mm are equal to 5dB/m and less. Chromatic dispersion equals to -120 ps/nmxkm, cut-off wavelength does not exceed 1,53 micrometers. External diameter of envelope equals to 80-100 micrometers, external diameter of coating equals to 160-200 micrometers. Adhesion property of surface of coating gum does not exceed 10gs/mm. Volumetric relation is reduced at least twice comparing to traditional module of dispersion-compensated fiber.
EFFECT: stable temperature characteristics; low losses; low dispersion of polarized mode in dispersion-compensated fiber.
