TruePhase 1550 fibers designed to operate at 1550 nm, maintain linear polarization and are available in standard and reduced buffer sizes. These fibers are made specifically for use with premium photonic devices such as phase-sensitive Lithium Niobate Modulators.
Used as a source laser pigtail, TruePhase 1550 fibers preserve the coherence of emitted laser light. The 250 buffer size is recommended for PMD compensators, which use longer lengths of fiber.
