Shenzhen E-Linkchina Technology Co., Ltd. has built fiber optic communication, video transmission and CCTV transmission equipment since 2001. This site presents its documented range — 440 catalogue models in 65 categories — organised the way engineers specify it: by link, by interface, by power class.
SDI in three generations, HDMI to 4K, DVI, USB, KVM and analog HD — the catalogue's headline range.
Industrial injectors from site DC power: 30W PoE+ to 100W 802.3bt PoE++, AI Smart Managed models included.
Power back out for non-PoE devices, and powered hops beyond the 100-metre channel.
Managed and unmanaged conversion, SFP-cage and OEO — copper to fiber at every rate to 10G.
Serial, E1, telephone and PDH: the legacy circuits, carried on glass without redesign.
PON-first module families — XGS-PON and GPON OLT — with SFP/SFP+ and QSFP shelves beside them.
Camera estates are built on fiber spines with copper clusters — and on combination hardware, like the documented extender that merges eight Gigabit PoE channels with forward and backward 3G-SDI on one fiber unit. Start from the architecture, then choose models.
Every page on this site follows the same discipline, and it is worth stating once, plainly. Models are listed by their official product names from the manufacturer's catalogue. Where a model's specification has been captured from its official product page, the page says so; where it has not, the model is listed with its series and a note that the full specification is confirmed at quotation. Model names are never treated as specifications, distances are never promised without a named optical module, and company self-descriptions are attributed as such.
Before payment, confirm the exact model, its fitted configuration and its full specification in writing. That sentence appears across this site because it is the sentence that prevents every classic failure in this industry — and we would rather repeat it than have you learn it.
Tell us the signal, the distance, the fiber and the quantity. The export team replies with the exact models and their confirmed specifications.
