FAQ

Q1: What single-mode fiber types are available for this bare optical fiber?

A: We offer three single-mode fiber options: G652D, G657A1, and G657A2.

Q2: What is the attenuation rate of this bare optical fiber?

A: The attenuation rate for this single-mode bare optical fiber is 0.35dB/km.

Q3: What cable lengths are available?

A: Available cable lengths include 100 meters, 200 meters, 300 meters, 500 meters, 1000 meters, and 2000 meters.

Q4: What connector options can I choose from?

A: We offer multiple pre-terminated connector configurations, including SC/UPC-SC/UPC, SC/APC-SC/APC, SC/UPC-SC/APC, FC/UPC-FC/UPC, FC/APC-FC/APC, and FC/UPC-FC/APC. You can also select the “No Need Connectors” option if you prefer raw bare fiber. The product generally supports FC, SC, ST, and LC connector styles.

Q5: What are the spool dimensions for the different cable lengths?

A: All spools have a uniform inner diameter of 5.3 cm and a height of 3.5 cm. The outside diameter varies by cable length:

  • 500 meters: 6.5 cm Outside Diameter
  • 1000 meters: 7.3 cm Outside Diameter
  • 2000 meters: 9.0 cm Outside Diameter

Sourcing these single-mode bare fiber spools in G657A2 and G657A1 specifications has significantly enhanced our custom optical component manufacturing line. The fiber consistently achieves the specified low attenuation rate of 0.35dB/km, providing excellent optical power budget preservation across long-distance and FTTA networks. The bend-insensitive G657A2 core strips cleanly and fuses effortlessly without micro-fracturing. Having access to spool lengths ranging from 100 meters to 2000 meters makes raw material planning efficient for varying production run sizes.

We purchased 1000m and 2000m spools of G652D bare single-mode optical fiber for benchtop testing and fusion splicer arc calibration. Selecting the "No Need Connectors" option gave us clean, raw optical fiber wound precisely onto standardized spools (featuring a uniform 5.3cm inner diameter with a compact 7.3cm to 9.0cm outside diameter). The fiber payout from the spool is smooth and snag-free during high-speed winding, and the 0.35dB/km attenuation performance fully satisfies ITU-T G.652D optical standards.

Ordering pre-terminated bare fiber assemblies with factory-installed SC/APC and FC/APC connectors saved our team a substantial amount of time during custom OTDR launch fiber preparation. The 0.35dB/km attenuation rate paired with high-precision SC/APC angled physical contact ferrule terminations ensured ultra-low back-reflection during link characterization. The availability of G652D, G657A1, and G657A2 single-mode fibers across diverse length options (from 100m up to 2000m) makes this an exceptionally versatile product line for telecom OEM suppliers.
