Tengchi G.657.A2 200µm Singlemode Fiber Datasheet
The 亮睿®+特微TM G.657.A2 200µm singlemode fiber from Tengchi (Nanjing) Fiber Co., Ltd. uses an optimized coating design that keeps the glass diameter the same as conventional 245 µm fibers while reducing the overall coating diameter. This enables superior optical and transmission performance across the full 1260‑1625 nm waveband and full compatibility with ITU‑T G.657.A2 and IEC 60793‑2‑50 standards.
Key characteristics include very low attenuation (≤ 0.34 dB/km at 1310 nm, ≤ 0.20 dB/km at 1550 nm), low dispersion, low PMD, excellent attenuation uniformity, and outstanding macro‑bend resistance (minimum bend radius 7.5 mm). The fiber is suited for FTTH, large‑core cables, micro‑cables and other high‑density deployment scenarios, reducing cable diameter and installation cost. This manual is written in Chinese.

Questions answered in 特恩驰 manuals
What is the minimum bend radius for the fiber and its loss at 1550 nm?
The fiber can be bent to a minimum radius of 7.5 mm with a loss not exceeding 0.5 dB at 1550 nm.
How does the fiber perform under humidity and temperature stress?
After 30 days at 85 °C and 85 % relative humidity, the additional attenuation remains ≤ 0.05 dB/km at both 1310 nm and 1550 nm.
