This page is the reference we point engineers, buyers and auditors to when they ask “what can the plant actually make, and how is it tested?” Everything below comes from our published datasheets and the factory test regime — not from a brochure.

What the published range actually covers

These ranges are computed from the specification tables on this site, so they describe real, quoted products rather than a theoretical maximum. The smallest item is GJFJH Indoor Single-Mode Breakout Cable with Tight-Buffered Fibres at 4.1 mm; the largest is GYTA33 GYTA333 Armoured Submarine and River Crossing Cable at 20.6 mm.

Parameter	Published range	Basis
Cable outer diameter	4.1 – 21 mm	covers FTTH drop cable through large duct cable
Fibre count	1 – 288 cores	single-core drop cable up to ribbon loose-tube duct cable
Allowable tensile force (short term)	200 – 10,000 N	short-term value per model; the long-term figure is typically one third to one half of it
Allowable crush resistance (short term)	105 – 1,200 N	per IEC 60794-1-2 E3 method; exceeds the 1000 N often specified for duct cable
Bending radius	10D static / 20D dynamic (standard families)	D = cable outer diameter; values differ by model, check each datasheet

Test regime: routine vs type test

The distinction matters in an audit. Routine tests run on every production length and the result goes on the test report shipped with the drum. Type tests are performed on a representative sample of a design and quoted on the datasheet; they are not repeated per drum.

Check	When	Method / reference
Attenuation at 1310 / 1550 nm	Every length (routine)	OTDR bi-directional, IEC 60793-1-40; single-mode limit 0.36 / 0.22 dB/km at 1310 / 1550 nm
Attenuation at 850 / 1300 nm	Every multimode length (routine)	IEC 60793-1-40
Length and fibre count verification	Every length (routine)	Drum counter cross-checked against OTDR trace
Visual and dimensional inspection	Every length (routine)	Outer diameter, sheath thickness, print legibility
Tensile strength	Type test	IEC 60794-1-2 E1
Crush resistance	Type test	IEC 60794-1-2 E3
Repeated bending / torsion / flexing	Type test	IEC 60794-1-2 E6, E7, E8
Temperature cycling	Type test	IEC 60794-1-2 F1, −40 to +70 °C typical for outdoor cable
Water penetration	Type test	IEC 60794-1-2 F5B, 1 m head, 24 h
Sheath integrity (spark test)	Every length (routine)	In-line DC spark tester on the sheathing line

What a buyer receives with each shipment: attenuation test report per drum, reel length list, and the applicable type-test report for the design on request. Third-party inspection (SGS, BV, TÜV) can be arranged at the buyer’s cost.

Product families and what each is for

Each row links to the specification table for that family. Use it when you need the model-level numbers rather than the range above.

Family	Typical models	Where it is used
Outdoor duct and aerial	GYTS, GYTA, GYTA53, GYXTW, GYFTY	Metro and backbone routes, duct and lashed aerial
ADSS aerial	ADSS, GYFTY83, GYFTY86, Mini ASU	Overhead power corridors, no messenger wire needed
Aerial figure-8	GYTC8S, GYXTC8S	Self-supporting aerial drops on existing poles
Direct buried	GYTA53, GYTA04, GYFTZY63	Underground routes, rodent and moisture protection
FTTH drop	GJXH, GJYXCH, GJYXFCH, GJYXFCH, hybrid GDXH / GDFJH	Last-mile subscriber connections
Indoor and data centre	GJFJH, GJSFJV, OM3 / OM4 breakout	Riser and plenum runs, patch panels, DC trunks
Mining and industrial	MGTSV, MGXTSV, MGTS33, GJFZY53(FR)	Flame-retardant routes, shafts, tunnels
Sensing and composite	GTSXY, SCTG33Y, GDXTW, GDVV	DTS monitoring, 5G RRU hybrid feed
Passive and accessories	PLC splitter, ODF, patch panel, adapters	Distribution and termination

Standards we quote against

Datasheets on this site reference the following. If your tender cites a different edition, tell us and we will state compliance explicitly rather than assume it.

• IEC 60793-1-40 — attenuation measurement
• IEC 60794-1-1 / -1-2 — optical cable generic specification and test methods
• IEC 60794-3 — outdoor cables
• IEC 60794-4 — aerial optical cables along electrical power lines (ADSS)
• IEEE Std 1222 — All-Dielectric Self-Supporting fibre optic cable
• ITU-T G.652.D — single-mode fibre, low water peak
• ITU-T G.657.A1 / A2 — bend-insensitive single-mode fibre
• YD/T 769 — China industry standard for outdoor optical cable

What we are not

Stating this plainly saves both sides time:

• We are a cable assembler, not a fibre drawer. Fibre is bought from tier-1 suppliers and comes with the supplier’s own attenuation certificate.
• We do not publish an ISO certificate number. Our management systems are established and operated to ISO standards; the certificate held by our parent company expired on 10 December 2023 and is therefore not quoted.
• We do not claim a monthly output figure. Capacity depends on the mix of models and is quoted per order after the specification is fixed.

Request the details

Send the route, fibre count and environment and we will come back with a model, a test plan and a lead time. Typical lead time is 7–15 days for standard models after drawing approval.
