G655 Single-mode optical fiber

Short Description:

DOF-LITETM (LEA) Single Mode Optical Fiber is a Non-Zero Dispersion Shifted Fiber (NZ-DSF) with large efective area.

Product Application

DOF-LITETM (LEA) is ideal for high data-rate, multi-wavelength long haul transmission. It has a large efective area for improved power handling plus dispersion optimized for dense wavelength division multiplexing (DWDM). It is suitable

for transmission in the conventional C-band (1530-1565 nm) and L-band (1565- 1625 nm). DOF-LITETM (LEA) exceeds the requirements of today’s high- channel-count 2.5 Gb/s and 10 Gb/s systems, and supports migration to next generation 40 Gb/s data rates.

Product Benefits

DOF-LITETM (LEA) has a large efective area for improved power handling plus dispersion optimized for dense wavelength division multiplexing (DWDM). This combination reduces the onset of non-linear transmission efects such as four-wave mixing and self-phase modulation, whilst also reducing the cost and complexity of dispersion compensation.

Manufacturing Process

We controls every stage of the manufacturing process so that quality is built in to every meter of fibre, rather than selected out at the end through testing. To ensure the accuracy and precision of the manufacturing process, we routinely calibrates and recertifies process equipment and measurement benches against internationally traceable standards from NPL/NIST, and follow test methods compliant with EIA/TIA, CEI-IEC and ITU standards.

International Standards

The DOF-LITETM (LEA) ccomplies with ITU-T G655 C & D Optical Fiber Specification.
