Featured concept
100G data center interconnect
A planning concept for short-reach 100G switch links: how to record the fiber path, size the optical budget and shortlist QSFP28 optics or DAC.

for real links.
Ten worked application concepts: what to document, which product families to evaluate, how the optical budget behaves and what belongs in the BOM. These are engineering references, not customer case studies.
Application concept
Campus fiber backbone
How to plan a multi-building campus backbone: fiber survey, 10G uplink classes, gigabit edge links and an optical budget that survives future re-patching.
Application concept
Single-fiber access connectivity
A reference plan for halving strand use with BiDi optics: matched wavelength pairs, budget arithmetic and media converters at the far end of the drop.
Application concept
Copper-to-fiber migration
A staged plan for replacing distance-limited copper runs with fiber: where converters fit, where copper SFP modules fit, and how to phase the cutover.
Application concept
25G server access links
How to plan 25G server-to-leaf links: adapter and switch inputs, SR versus LR selection, breakout from 100G, and acceptance against FEC counters.
Application concept
Industrial cabinet connectivity
Planning network connectivity inside plant cabinets: temperature grades, DIN-rail switches, DC supply, vibration and fiber uplinks out of the noise floor.
Application concept
Fiber links for IP surveillance
A planning reference for camera backhaul over fiber: bandwidth per stream, converter placement, single-fiber drops and recorder-side aggregation.
Application concept
FTTx and PON-adjacent gigabit access with BiDi SFP
A planning concept for point-to-point gigabit access built on BiDi SFP optics: wavelength plans, aggregation sizing and subscriber-side termination.
Application concept
Metro and long-haul links beyond 40 km
Planning links of 80 to 120 km: 1550 nm budgets, APD receivers, chromatic dispersion, amplification choices and the measurements that must precede ordering.
Application concept
PoE camera and outdoor edge connectivity
Planning powered edge devices outdoors: PoE class budgeting, temperature grades, DC supply sizing, surge exposure and where the fiber boundary belongs.
Note
These are planning concepts.
Every page on this list describes how a class of link is planned and specified. None of them claims a delivered customer project, a named site or a measured result.
