DWDM stands for Dense Wavelength Division Multiplexing. It sends many independent data channels over a single fibre pair, each on its own wavelength (colour) of light. A multiplexer combines the wavelengths at one end and a demultiplexer separates them at the other, so you can multiply the capacity of fibre you already own or lease, from 10G up to hundreds of gigabits per wavelength, without laying new cable.

DWDM is a Layer 1 (physical layer) technology. It transports light on the fibre and is transparent to the protocols it carries, so Ethernet, Fibre Channel and OTN services can share the same fibre. That's also why PacketLight encrypts at Layer 1: every bit on the wavelength is protected, whatever the protocol.

Dark fibre is optical fibre that is installed but not yet lit by any equipment. Organisations lease or buy it to build private, high-capacity links between their own sites, such as data centres, trading floors, campuses or government facilities. You light dark fibre with your own equipment, and PacketLight DWDM lets one fibre pair carry many separate 10G, 100G or 400G services at once, so you get far more value from every fibre you lease.

Both send multiple wavelengths over one fibre. CWDM (Coarse WDM) uses widely spaced channels (20 nm), supports up to 18 channels and suits shorter, lower-cost links. DWDM uses tightly spaced channels in the C-band, supports far more channels and higher speeds, and can be amplified with EDFAs for long-distance routes. For 100G–600G capacity, Layer-1 encryption and long reach, DWDM is the right choice. Our engineers will tell you which fits your link.

A muxponder aggregates several lower-speed client services into one high-capacity DWDM wavelength. A transponder maps one client signal to one wavelength. Platforms like the PacketLight PL-4000M mix 10/25/100GbE, 16/32G Fibre Channel and OTU2/OTU4 services onto 100–600 Gbps coherent uplinks, which saves wavelengths and fibre.

Layer-1 (optical) encryption protects data on the transport layer itself, below Ethernet and IP. Every bit on the wavelength is encrypted at full line rate, whatever the protocol, with negligible added latency and no loss of throughput. IPsec and MACsec work higher in the stack and add overhead. PacketLight uses GCM-AES-256 with EC Diffie-Hellman key exchange, certified to FIPS 140-2/3 Level 2.

The PL-4000M supports up to 600G per 1U chassis, with dual CFP2-DCO or QSFP-DD coherent uplinks running at 100–600 Gbps. It combines high capacity, built-in AES-256 Layer-1 encryption and hot-swappable optics, power and fans in a compact carrier-grade unit. Ask us for the PL-4000M datasheet or a sizing for your link.

Reach depends on your fibre, the data rate and the modulation. PacketLight supports flexible modulation, from QPSK for long-haul routes to 16-QAM for high-capacity metro and DCI links, and EDFAs extend distance where needed. Our engineers calculate a link budget on your actual fibre route before recommending a design.

Yes. PacketLight is legacy-friendly. It interoperates with third-party transponders, amplifiers and existing fibre plant, so you can upgrade capacity or add encryption without a full rip-and-replace.

PacketLight gives full service and OTN visibility and integrates with the Viavi ONMSi Optical Network Management System. ONMSi adds full optical-layer monitoring with real-time alarms, analytics and fault isolation, all without affecting the transport wavelength. For high-security links, VIAVI FTH-5000 real-time fibre monitoring can also detect fibre breaks, physical disturbances and potential tapping attempts.

We combine EDFAs, optical switching, 1+1 OTN protection and multi-path routing to remove single points of failure. For a leading financial institution in Sydney, Cloudtronics deployed a four-path, fully redundant 400G DWDM network with Layer-1 encryption, built on the PacketLight PL-4000M with PL-1000IL and PL-300 for optical switching and amplification, and designed to stay up through multiple concurrent fibre failures.

Yes. Clients across Australia and Southeast Asia rely on Cloudtronics. We have offices in Sydney and Melbourne, an office in Indonesia and an R&D lab in the USA.

Pricing depends on the number of sites, link distances, capacity per link, protection (redundancy) and whether you need Layer-1 encryption. Send us those details through the quote request form.
