What is the difference between optical Ethernet and PON?
Point-to-point optical Ethernet assigns an Ethernet link to each access device. H3C multichannel Ethernet can carry separate Ethernet channels through a matched passive assembly. PON instead uses an OLT, passive splitters and registered ONUs that share a PON port. Compare usable busy-hour bandwidth, optical loss, endpoint power, management, compatibility and migration effort—not just the amount of fiber.
Is an all-optical network suitable for every building?
No single architecture fits every site. Existing certified copper, available floor rooms, route distances, local power and maintenance skills may favor conventional Ethernet. Fiber may help long routes or distributed access, but APs, ONUs and switches still need electricity. Start with the retained assets and service requirements, then compare complete equipment, cabling, power and operating costs.
Can you design a network from architectural drawings?
Yes. Drawings help establish zones, routes, equipment rooms and proposed device positions. We also need intended use, client/device counts, existing systems and required services. The first deliverable can identify assumptions and missing inputs; RF coverage, actual cable condition, optical loss and installation constraints need site verification before a final construction or purchasing release.
Can we keep some existing switches and cabling?
Often, after checking model/release support, available ports, uplink capacity, PoE budgets, fiber measurements and copper test results. A migration schedule should label each item retain, replace or add, show temporary interconnections, define the outage and rollback plan, and test voice, video, authentication and management before the next zone is moved.
How do you select H3C models for a project?
We start with device roles and exact interfaces, then check capacity, environmental conditions, power input/output and required software. The full model suffix matters: FS5500V2-24UXS6Y-EI has base 2.5GE access and licensed upgrades on selected ports, while ES4200-8P2RX-B has different PoE budgets under local and remote power. The proposed model, accessories and unresolved configuration items are listed together.
Are transceivers and licenses included in the quotation?
They are included only when expressly listed. Ask for quantity and exact SKU of both optical ends, fiber/connector type, wavelengths, rated loss/distance, PSU/fan sets and feature/AP/security licenses. Multichannel optics must be a matched generation/set; PON needs the correct OLT board, optic class and ONU interoperability. A chassis price alone is not a complete network BOM.
How are APs and access devices powered?
Use a compatible PoE copper port, local AC/DC adapter, or an approved hybrid fiber/copper power system. Glass fiber carries data only. Hybrid cables use electrical conductors alongside fiber and need voltage-drop, gauge, length and receiver checks. Calculate each PSE port limit and total switch/ONU budget, including startup, losses, reserve and the required single-supply failure condition.
Can the network carry CCTV, IPTV and IP phones?
Yes, when interfaces and service requirements are compatible. CCTV adds sustained recording traffic and storage/retention demand; IPTV may require multicast with an IGMP querier and controlled replication; phones need the supported SIP/PBX platform, power and QoS. Define VLANs, routing/ACLs, DHCP/DNS, time synchronization, peak demand and backup power, then test the actual endpoint/software combination.
Can H3C equipment work with other brands?
Standards-based Ethernet and selected optical links can interoperate when speed, wavelength, connector, fiber and configuration match. That does not guarantee proprietary management, stacking, PON ONU registration or hybrid power compatibility. Give us the exact other-brand model and firmware so the common protocol path, unsupported functions and required bench tests can be identified.
Do you provide wholesale project pricing?
NexPro-Link supplies H3C and partner-brand equipment with wholesale and project quotations. Send models and quantities if you have a BOQ, or drawings if selection is still open. The offer confirms exact configuration, regional availability, accessories, licenses, warranty/support scope, payment and delivery terms. No fixed discount, stock position or lead time is implied by these reference pages.
What information is needed for a network BOQ?
Start with the country, building use, new-build/upgrade stage, drawings or current device list, and the services to connect. Useful follow-up inputs are port/client counts, distances, fiber/copper tests, power and UPS needs, security boundaries, availability targets and preferred brands. Use the downloadable checklist and leave unknown fields blank; uncertain quantities are identified before quotation.
Are the displayed projects actual installations or reference designs?
These six projects are reference designs prepared to explain architecture, model selection and BOM structure. They are not claims of completed customer installations. Each states its assumed scale, port/power calculations and outstanding site inputs. Official H3C product photographs or hardware drawings are identified separately from application imagery, and model sources are linked beside the specifications.
