Draka’s Enhanced Single-Mode Fiber (ESMF) provides improved performance across the entire 1260 nm to 1625 nm wavelength spectrum. It has a low dispersion in the 1310 nm window and low attenuation in the 1383 nm water-peak region to allow use of the extended band (1360 nm to 1460 nm). With its wide operating spectrum, ESMF expands the future growth capability of the fiber and allows flexible configuration of voice, data, and video services within the fiber. It can be used in all cable constructions, including loose tube, tight buffered, ribbon, and central tube designs.

The tighter geometrical, attenuation and PMD specifications of ESMF enable superior performance in long-haul, metropolitan, access and premises applications in telecommunications, CATV and utility networks. ESMF is completely interchangeable with standard single-mode fiber.

Draka’s Advanced Plasma and Vapor Deposition (APVD™) manufacturing process ensures the highest quality and purity of fibers. Proprietary ColorLock™ coating process further enhances the performance, durability and reliability of the fiber, even in the harshest environments.

The fiber complies with or exceeds the ITU-T Recommendation G.652.D, the IEC International Standard 60793-2-50 type B.1.3 Optical Fiber Specification, Telcordia GR-20-CORE, ANSI/ICEA S-87-640 and RUS 7CFR 1755.900.

Features:
• Low 1383 nm (water-peak) attenuation
• Low hydrogen sensitivity
• Lower PMD of 0.06 ps/√km link design value
• Low 1460 nm attenuation (< 0.25 dB/km)
• Proprietary APVD™ manufacturing process
• Revolutionary ColorLock-XS coating process

Advantages:
• Provides expanded fiber capacity and cost savings through use of cheaper lasers in the entire 1260 to 1625 nm range, multiplexing filters and higher number of channels
• Low attenuation in the 1383 nm region even as fiber ages, for improved performance and long life
• Extends the PMD distance performance, reducing regeneration costs
• Easy design of low cost laser and filter based systems over a wide wavelength range
• Ensure efficient Raman pumping for C-band amplification
• Superior geometry, uniformity and purity
• Increased reliability, durability, and superior aging performance, resulting in lower maintenance and replacement costs. Makes color a component of the coating, thus enhancing fiber identification and colored fiber reliability. Consistent, vibrant color for easy-of-use and flexibility
