RFQ worksheet (CSV)
The fields we need for an accurate quotation: rate, form factor, host, fibre, reach, quantity and destination. Opens in Excel or Sheets.
Link planning checklist (CSV)
A row per link: host ports, fibre grade, measured loss, connector, environment and the module you intend to use.

How to choose the right optical transceiver for your network
Work from host port to finished RFQ: form factor, reach class, fiber grade, loss budget, wavelength plan, temperature grade and platform coding.
Network design
DAC or AOC: what should your RFQ include?
Passive and active copper, AOC construction, reach limits per data rate, breakout options, power, bend radius and the coding both ends need.
