Unlit pairs. Long-term IRU. Your transponders, our right-of-way.
Single-mode G.652.D pairs between addressable A and Z endpoints across our Punjab footprint. You light it the way you want — coherent, grey optics, OTN, doesn't matter — we hand you a measured, OTDR-baselined fibre and keep it that way for the term.
A glass pair on long-term lease.
Dark fibre is the underlying transport layer of any modern network: a pair of single-mode strands between two physical points, with no electronics from us in the path. We hold the right-of-way, the duct, the splice closures and the OTDR records. You bring the terminating equipment and decide what runs on it — 100G coherent today, 400G tomorrow, OTN, dark-wave, point-to-point Ethernet, or a private DWDM line system.
Our Punjab footprint is built on terrestrial long-haul between Lahore, Faisalabad, Multan and Islamabad, with metro builds inside Lahore (Gulberg, Johar Town, Cantt, DHA, Sundar industrial estate), Faisalabad (industrial estate + Madina Town) and Islamabad (Blue Area, I-9, I-10). For new endpoints we run a route study, walk the last mile, and quote build versus IRU based on what we already have in the ground.
Built for operators that want the layer below.
Dark fibre customers are typically running a network of their own. If you'd rather buy a circuit, look at DPLC.
Carriers extending reach
Other LDIs and metro carriers IRU pairs from us where their build doesn't cover — Bahawalpur, DG Khan, Sahiwal, the Sundar industrial belt.
Hyperscaler / cloud edges
Operators landing capacity into Lahore or Islamabad and pushing it onto our pairs to reach customer DCs without sub-leasing managed bandwidth.
Banks running their own DWDM
Tier-1 banks with in-house transmission teams who want a guaranteed pair between primary and DR sites and no shared SLA risk.
Mobile backhaul aggregators
MNOs aggregating BTS clusters who need predictable fibre cost between their MSCs and macro-cells.
Research & defence networks
Closed networks where layer-1 isolation is a contractual requirement, not just a preference.
DC operators inside Punjab
Carrier-neutral facilities that want pairs into peering DCs and submarine landings reached via Karachi.

From request to lit pair.
- 01
Route study
Day 0 – 5. We confirm A/Z addresses, walk last mile if needed, mark splice points and quote build vs IRU.
- 02
Order + civil
Day 5 – 30 if civil works are required. Permits, microtrenching or conduit pull, splice closures.
- 03
Splicing + OTDR
Day 25 – 40. End-to-end splice, OTDR sweep both directions, loss budget signed off.
- 04
Handover
Day 35 – 45. Cabinet rack-and-stack, LC handoff, OTDR PDF and as-built drawings handed over.
Typical end-to-end timeline 30–45 days where existing pairs are available; new builds are quoted with their own civils schedule.
What customers ask before signing.
Do you sell strands or pairs?
What's the longest A–Z route you can deliver as a single pair?
Do you support G.654.E for high-power coherent?
Can we co-locate amplifiers/transponders at your POPs?
What happens on a fibre cut?
Do you offer 1+1 georedundancy?
How is pricing structured?
If dark fibre is too low-level — buy the layer above.
