China–Hong Kong dedicated lines
100G across multiple border crossings
The risk on an international link is rarely raw bandwidth — it is a single route failing and taking the business with it. International segments are carried over the licensed international networks of China Mobile CMI, China Unicom CUG and China Telecom CTG; Fredyun converges them into multiple 100G paths across different border crossings that back each other up.
What this service covers
Multi-crossing 100G transport
Multiple 100G circuits over different border crossings on a 400Gbps global backbone, with dynamic routing that avoids congestion at any single crossing.
IEPL / MPLS / SD-WAN
Mix and match transport types; international and domestic segments planned as one wide-area network.
Dark fibre
Point-to-point dark fibre with dedicated, physically isolated bandwidth — suited to financial institutions and data-centre interconnect.

How to think about it
Where the international capacity comes from. CMI, CUG and CTG hold China's international telecom licences and supply the circuits. Fredyun buys that licensed capacity and does the work on top of it: converging the three networks, steering routes, provisioning end to end and running the service. Fredyun's own licence is a trans-regional value-added telecom licence (B1-20235481) covering IDC, ISP, CDN and domestic internet VPN — trans-regional, not international.
What that structure buys you. When one carrier's international path congests or fails, traffic moves to one of the other two. You do not sign three contracts, manage three relationships or arbitrate three fault tickets. Converged routing, a single SLA and one accountable party is the layer Fredyun adds.
Choosing a transport type. IPLC is an end-to-end dedicated circuit that never touches public-network equipment — the most stable latency and jitter, the right answer for trading and replication. IEPL delivers point-to-point bandwidth as Ethernet and is far easier to configure and scale; it is the workhorse of international networking. MPLS suits many-site any-to-any topologies. SD-WAN sits above all of them, steering applications across whichever links exist. In real projects they coexist.
Licence scope
International and Hong Kong / Macau / Taiwan capacity is not built by Fredyun. China Mobile International (CMI), China Unicom Global (CUG) and China Telecom Global (CTG) hold the international telecom licences and supply the underlying circuits. Fredyun procures that licensed capacity and delivers convergence, routing, end-to-end provisioning and operations on top of it.
Fredyun itself holds a trans-regional value-added telecom business licence (B1-20235481) issued by China's Ministry of Industry and Information Technology, covering IDC, ISP, CDN and domestic internet VPN — trans-regional, not international. This boundary is stated explicitly in every proposal and contract.
What clients ask most
Which border crossings does the international segment use?
Traffic runs over multiple 100G circuits across different border crossings rather than depending on any single one. That capacity comes from the licensed international networks of China Mobile CMI, China Unicom CUG and China Telecom CTG; Fredyun converges them into three physically isolated backbone routes, so a failure on any one network moves traffic to a backup without interruption. Global backbone capacity is 400Gbps.
Can you reach HKEX? Do you do exchange connectivity?
Yes. Fredyun provides HKEX SDNET access with microsecond-class latency for trading systems, and exchange connectivity across APAC and to CME in the United States. These sit in the ultra-low-latency international financial line portfolio; access points, redundancy design and latency targets are fixed during solution design.
What is the difference between IEPL and IPLC?
IPLC is an end-to-end dedicated circuit that does not traverse public-network equipment, giving the most stable latency and jitter. IEPL delivers point-to-point bandwidth over Ethernet and is more flexible to configure and scale. Trading and replication workloads that need determinism usually take IPLC or dark fibre; conventional international networking usually takes IEPL. The link survey stage produces a recommendation against your latency target.
What availability do you commit to?
PoP-to-upstream-ISP availability 99.99%, end-to-end link availability 99.5%, 24/7 monitoring with proactive alerting, overall service fulfilment above 98% and 100% VIP fault tracking. The SLA for a specific circuit is confirmed during solution design alongside the T&Cs and delivery milestones.
Is Fredyun licensed?
Fredyun holds a trans-regional value-added telecom business licence (B1-20235481) issued by China's Ministry of Industry and Information Technology, valid 16 Jan 2024 – 14 Nov 2028, covering IDC (31 cities), ISP (nationwide), CDN (nationwide) and domestic internet VPN (nationwide). It has also passed China's Multi-Level Protection Scheme (MLPS/等保) and holds ISO 27001 and ISO 9001 certification. Note that this is a trans-regional licence, not an international one — international and HK/Macau/Taiwan capacity comes from the three carriers named above.
How long does provisioning take?
3 days to 1 week where both ends are inside existing PoP coverage; about 2 weeks where a new access segment or dark-fibre build is needed. The exact schedule is confirmed after the link survey, together with the solution and delivery milestones.
