Company profile

Optical access and fiber power, specified as one chain.

Guanheng is a supplier and specification partner for PON access, Power over Fiber, PoE switching and 1550 nm transport. We size the chain and supply the documents; the local contractor installs it.

Supplier + specification partner

A supplier that shows the arithmetic

Guanheng supplies optical access and fiber-power equipment to integrators, contractors, project owners and distributors in Southeast Asia, Africa, the Middle East and South Asia. The range covers GPON/EPON/XGS-PON OLT and ONU, PLC and PoF splitters, PoE switches, hybrid cable and 1550 nm transmission.

The work starts before the product: an endpoint list, a distance, a load and a mains condition. From those four facts we calculate the optical budget and the power budget, then choose the chain. The quotation states the split ratio, the connector polish, the PoE/PoF load and the assumptions it uses.

Equipment comes from qualified manufacturing partners. We confirm the model-level datasheet and test documents, keep the connector and PON mode consistent, and support the integrator through the pilot and the handover. We do not claim a factory we do not own, and we do not publish a case study without permission.

How a project moves

Five steps from site data to handover

Site data sheet

Endpoint count, distance, mains, load and country. The input table that everything else follows.

Optical and power budget

Split ratio, fibre/connector/splice loss, 3 dB margin and the PoE/PoF load, written down.

Bill of materials

The chain and the spares, with the assumptions and the model-level documents attached.

Pilot / FAT

One site or one batch configured and tested on the actual headend before the rollout.

Delivery and handover

Staged shipment, as-built labels, test records and the document pack.

Why buyers work with us

Four things a catalogue cannot do

Specification first

We start from the endpoint, the distance and the mains condition, not from a model number.

One bill of materials

OLT, splitter, ONU, PoE/PoF and cable are quoted as one chain, so the interfaces match.

Model-level documents

Datasheet, test data and certificates are supplied for the quoted model — not as a blanket claim.

Export support

Packing list, HS code, Incoterm and staged delivery are agreed before the shipment leaves.

Applications

Where the chain is used

CCTV, outdoor wireless, campus and FTTH are the four most common starting points. Each design begins with the place, the device and the distance.

Certifications & Recognition

Documents that travel with the model

Equipment is produced by qualified manufacturing partners under ISO 9001 quality systems. CE, RoHS and FCC documents, model-specific test reports and optical power test data are supplied with the quotation for the selected model. The images below are representative; the model-level file is the controlling document.

CE compliance documents RoHS compliance FCC documents (where applicable) Manufacturing partner ISO 9001 Model-specific test reports Optical power test data Export packing inspection IEC / EN standards referenced

Representative certificates are shown. Model-level certificates and test reports are supplied with the quotation for the selected model.

Partner production network

Where the equipment is built and tested

Photos from the qualified manufacturing partners that build the models we supply. These are partner facilities, not an Guanheng-owned factory.

Production and test

SMT, assembly, ageing, optical test and packing

The production photos cover the processes that matter for a PON or PoE unit: board assembly, final assembly, ageing, optical power test and export packing.

OEM / ODM

Customisation, quoted per project

Logo, label, packing and documentation are the usual starting points. Port mix and enclosure changes need a tooling and quantity discussion.

Logo and label

Product label, silkscreen and packaging branding on project quantities.

Packing

Retail or project cartons, palletisation and moisture protection for the destination.

Documentation

Manual, datasheet and label set in the agreed language.

Port configuration

Port mix, PoE/PoF outputs and connector polish discussed against the project BOM.

Company profile

What we do, and what we do not

01Sourcing and specification

We select models from qualified manufacturing partners and verify the datasheet against the project requirement. The same chain may combine PON access, PoE switching, PoF and 1550 nm transport, so the interfaces are checked together rather than bought separately.

02Optical and power budgeting

Every project quote includes the worst-case optical budget and the PoE/PoF load. The calculation includes splitter loss, fibre loss, connectors, splices and a 3 dB ageing margin. If the margin is negative, we change the split or the route before quoting.

03Documentation and export

Model datasheets, splitter batch test data, packing list, HS code and Incoterm accompany the order. We do not act as the importer of record; the buyer or the buyer’s broker confirms the classification, duty and type approval.

04Scope boundary

We supply equipment, design support and documentation. Cable trenching, splicing, installation and commissioning are carried out by the local contractor or integrator. We support the commissioning remotely and do not claim installation capability we do not have.

Six answers are enough to start: endpoint count, longest run, mains condition, load per device, country and services. If a number is missing, we state the assumption instead of hiding it.
