GJXFH, GJXH, GJYXCH: Nahea ia ma'iti i te taura FTTH tano no ta outou opuaraa

Noa'tu e, ua faahiti mai ta outou taata hoo tao'a ia outou e pae numera taa ê no te mau hoho'a taura — GJXFH, GJXH, GJYXCH, GJYXFCH, GJFJU. You need to answer one question before the PO can move: which one does this project actually need?

This guide is written for the person doing that decision. It skips the “what is a fiber drop cable” refresher (that lives in our Te hoê buka arata'i no te mau hoho'a) and gets straight to model-level selection.

If you buy for an FTTH rollout, resell drop cables to regional ISPs, or spec them into a project design, you will finish this in about ten minutes and walk out with a defensible model pick.

What the Letters in GJXFH Actually Mean

Chinese drop cable model codes follow the YD/T 1258 telecom standard. Once you learn the pattern, every future model name reads like a spec sheet:

Letter	Te auraa	What it tells you about the cable
G	Communication-use optical cable	It is a telecom optical cable, not a copper or power hybrid
J	Indoor use (as a prefix)	Ua hamanihia na mua ' ' e no te faaohipa i roto i te fare
Y	Te faaohiparaa i rapaeau (as a prefix)	Ua hamanihia no te mau vahi i rapae
X	Bow-type / tuha'a manu rere	Te fare tahua, hoho'a mai te va'u hoho'a
F	Melo o te puai (Te faatumu i ni'a i te hoho'a)	A hi'o i te faaararaa i raro nei
C	Te patururaa ia'na iho na roto i te hoê ve'a taa ê	E arapoa fetia aore ra FRP to'na no te tape'a i to'na iho afa'i
H	Sheath (ei suffix)	E tapao i te ahu o waho
J (i ropu i te waehere, e.g. GJFJU)	Aramid / KFRP hu'ahu'a puai	Te haapuraa taatoa e ere i te mea metala

GJXFH — The Indoor Bow-Type Workhorse

GJXFH is what most residential FTTH rollouts install between the building’s distribution box and the subscriber’s ONT. It is designed for indoor conditions: temperature-stable environments, protected pathways, moderate pulling forces during initial installation.

Typical 1-fiber GJXFH datasheet (based on a real production spec):

Parameter	Iteraa rau o te peu maitai
Numera o te Fiber	1 (also 2 / 4-core versions)
Te huru o te Fiber	G.657.A2 bend-insensitive single mode
Attenuation @1310 nm	≤ 0.4 dB/km
Attenuation @1550 nm	≤ 0.3 dB/km
Macro-bending loss @1625 nm, 7.5 mm × 1 turn	≤ 1.0 DB
Jacket dimensions	3.0 × 2.0 mm (LSZH, black or white)
Melo o te puai	0.5 mm (steel or FRP, confirm on PO)
Long-term tensile load	40 N
Short-term tensile load	80 N
Min. radius piko (Te mau mana'o tauturu no te / Te mau mana'o tauturu no te)	30 mm / 15 mm
Te anuvera e tere ra	-40 i te +70 °C
Te anuvera o te haaputuraa	-40 i te +70 °C

Why G.657.A2 matters more than the price tag

Two drop cables can look identical on paper, differ by only $0.02 i te metera, e a rave noa â i te hoê maitiraa taa ê roa no te oraraa a muri a'e o ta outou taata hoo.

G.657.A1 E faatere oia i te mau pi'o au noa, tera râ, e ino roa ' tu â i raro a'e i te ~10 mm radius.G.657.A2 — te hu'ahu'a i roto i te faataaraa i ni'a nei — e tape'a ïa i te hoê faito teitei 1.0 dB o te ereraa i te macro-bending noa'tu i te hoê 7.5 mm radius i te 1625 m.

Na te aha e 1625 nm ohipa? No te mea ho'i e, i taua matapihi roa ra, te vai ra te mau ma'i e te oraraa a muri a'e o te faanahoraaTe haamaitairaa XGS-PON 10G te ora nei te mau tapa'o. Ia haamaitai ana'e te hoê ISP i te 10G FTTH, e nehenehe te hoê ISP e faaohipa i te A1 i teie mahana, e faaruru i te hoê taura faaho'i-faahou-raa moni rahi, no te mea eita ta te mau hu'ahu'a tahito e nehenehe e tapea i te taiva ore o te tapao i raro a'e i te hoê â mau pi'o. Te hoê taura A2, i te pae hopea, te hoê faanahoraa parururaa moni iti no te pato'i i te faaauraa i te faanahoraa i muri iho a te taata faatere.

Te mana'o paraparau a te taata tufa:
Ia faaho'i ana'e te hoê taata hoo tao'a i ta outou hoo GJXFH no te mea e $0.03/m moni iti a'e te hoê tata'uraa, ask which fiber grade the cheaper cable uses. If it is A1, you can honestly say: “That $0.03 saving becomes a full re-cabling cost when they move to XGS-PON in three years.” Buyers who buy for operators care about that math.

When not to use GJXFH

Indoor design means indoor use. Do not deploy GJXFH outdoors on an aerial pole or in a self-supporting span. The LSZH jacket is not formulated for continuous UV exposure, the thin cross-section will not survive ice load, and there is no messenger wire to carry the cable’s own weight over any distance.

If a buyer asks you whether “GJXFH outdoor” versions exist, the honest answer is no. What they need isGJYXCH e aore râ,GJYXFCH — outdoor cables with an integrated messenger. Read on.

GJXH — Steel-Reinforced Indoor Bow-Type

GJXH is often used interchangeably with GJXFH in supplier catalogues, and the confusion is real. In our reading of the market, the practical distinction is this: GJXH consistently ships with a phosphated steel wire strength member and slightly higher tensile ratings than the FRP-marked variant.

Typical 2-fiber GJXH datasheet:

Parameter	Iteraa rau o te peu maitai
Numera o te Fiber	2 (also 1 / 4-core versions)
Te huru o te Fiber	G.657.A2 (confirm A1 vs A2 on order)
Attenuation @1310 nm	≤ 0.4 dB/km
Jacket dimensions	3.1 × 2.0 mm (LSZH, taata ereere)
Melo o te puai	2 × 0.45 mm phosphated steel wire
Long-term tensile load	100 N
Short-term tensile load	200 N
Min. radius piko (Te mau mana'o tauturu no te / Te mau mana'o tauturu no te)	60 mm / 30 mm
Te anuvera e tere ra	-20 i te +60 °C

The most common mistake with GJXH

We have seen technicians pull GJXH through 20-meter conduit runs, up ceiling voids, or across short aerial spans. In every one of those cases the deployment worked on day one and produced customer complaints six months later — micro-fractures inside the fiber, gradual attenuation creep, and a service call to replace the run.

A 100 Te auraa no te hoê tau maoro N, o te auraa ïa e, e nehenehe te taura e tape'a i to'na iho poihâ e te puai hutiraa au noai muri a'e i te faautaraa ' tu e te static. E ere te auraa e e nehenehe ta outou e huti i te reira 15 metera no te pato'i i te friction. Mai te mea e, e hinaaro ta outou taata faauta i te hoê puai hutiraa faufaa, I te rahiraa o te taime, GJYXCH i te 300 N taime roa, noa'tu te hoê tauiraa poto i roto i te fare e i rapae.

Eaha mau te auraa o te parau " patururaa ia'na iho "

E mea faufaa te parau. E amo te hoê taura toparaa ia'na iho i to'na iho teimaha pohe e te mata'i, e (i roto i te mau vahi toetoe a'e) te hopoi'a toetoe, ma te titau ore i te hoê arapoa taa ê. Na te vea i amuihia i roto i te GJYXCH e rave i te reira.

For spans up to ~80 meters this design is efficient and cheap. Beyond 80 meters — think longer road crossings, river crossings, or rural aerial runs between poles further apart — the messenger geometry no longer holds the required sag and tension. That is where ADSS cable takes over.

Two common misuses

Do not direct-bury GJYXCH. The jacket is not designed for soil contact, moisture pressure, or rodent load. For direct burial, spec an armored outdoor cable such as GYTA53.

Do not exceed the max span. We have watched installers hang GJYXCH across 100-meter road crossings “just this once” because ADSS was not on hand. Within one storm season, cable sag exceeded compliance limits and pole loading became a safety risk. Match the design to the span, not the calendar.

Bottom Line — Match the Model to the Deployment

Buying a drop cable well is an act of translation. The customer says “we need FTTH last-mile,” which really means “we need the specific model that fits this deployment’s environment, tension profile, EMI risk, e te huriraa o te oraraa.” E faariro te tumu raau faaotiraa i nia nei i taua huriraa ra e maha uiraa.

Eaha te hoê taura FTTH e paturu ia'na iho?

A self-supporting drop cable has an integrated messenger element — usually a steel wire in GJYXCH or an FRP rod in GJYXFCH — that carries the cable’s own weight across an aerial span between two support points, typically utility poles. This eliminates the need for a separate lashing wire, simplifying aerial installation. Typical maximum span is ~80 meters; longer runs should use ADSS cable instead.

What is the maximum aerial span for a GJYXCH drop cable?

Approximately 80 meters between support points, under standard conditions. Beyond that distance, cable sag exceeds compliance limits under wind and ice load, and the messenger tension can compromise pole hardware. For spans between 80 e 200+ Te mau mana'o tauturu no te, deploy ADSS cable, which is engineered for longer aerial runs.

Can I bury GJYXCH cable directly underground?

Aita. Ua tapo'ihia te GJYXCH no te faaite i te UV e te huru o te reva, eiaha no te tape'araa i te repo, Te faaheporaa i te haumi i ni'a i te repo, e aore râ, te parururaa. No te tanuraa ti'a'tu, a faaohipa i te hoê taura tama'i mai te GYTA53 e te hoê taura tama'i e te hoê ahu tano.

Ehia roaraa te hoê taura FTTH matauhia i te hoê reel?

I te rahiraa o te taime, o te roaraa o te reel 2 i te 3 kilometera no te GJXFH i roto i te fare / GJXH e i rapa GJYXCH. Hou a faaoti ai i te PO, a haapapû i te ô ti'a e te mau titauraa atoa no te roaraa o te opuaraa e ta outou taata hoo.

Eaha te puai o te hoê taura toparaa e hinaaro mau no ta ' u opuaraa?

Te faataahia ra te reira i ni'a i te huru o te faautaraa, aita i ni'a i te i'oa o te taura. I te rahiraa o te taime, e titau te mau faanahoraa poto i roto i te fare i te 40–100 N (GJXFH e aore râ, GJXH). Te hutiraa mai i te, i ni'a i te tapo'i, and short aerial transitions require higher rated cables — even for short outdoor spans, spec GJYXCH at 300 N taime roa. Under-speccing the tensile rating is the single most common cause of latent micro-fracture failures we see in the field.

How do I verify drop cable quality before accepting delivery?

Request a factory OTDR trace and attenuation report for every reel, keyed to the batch number. Visually inspect the sheath for consistent color, embedded print marking, and no material inconsistency. Random-sample a short section from each shipment, tatara i te ahu, and confirm that the strength member material physically matches your PO specification. Any mismatch between the PO and the actual construction should trigger an immediate quality dialogue with the supplier.

What fiber grade should I specify for future-proof FTTH deployments?

A faataaG.657.A2 e aore râ, teitei a'e. Older-generation G.657.A1 fiber shows significant macro-bending loss at bend radii below 10 mm, especially at 1625 nm — the wavelength window used for XGS-PON 10G FTTH network expansion. Deploying A1 today may force an operator into a costly network re-cable when they upgrade. A2 fiber holds ≤ 1.0 dB loss at a 7.5 mm radius i te 1625 m, effectively covering the operator’s next upgrade cycle at a marginal cost premium.
