Metro DWDM
Reach calculator, wavelength plan, dB margin review, and 100G/400G module selection for resilient metro routes.
Finisar solution work combines product selection, link budgeting, compliance references, sample coordination, and field handoff. The packages below are written for teams that need an answer beyond a shopping cart: what will work, what should be tested, what data should be kept, and how the NOC should be prepared.
For a metro carrier, that may mean 100G DWDM optical transceiver planning with amplifier assumptions. For an FTTH provider, it may mean GPON splitter guidance and OPEX modeling. For an enterprise or datacenter team, it may mean a disciplined QSFP-DD rollout with thermal notes and replacement stock planning.

Reach calculator, wavelength plan, dB margin review, and 100G/400G module selection for resilient metro routes.
GPON and XGS-PON split planning, ONT handoff notes, outside plant guidance, and low-loss connector discipline.
QSFP-DD thermal review, MPO polarity planning, 400G ZR+ selection, and port traceability for dense switch fabrics.
Compliance package, sample logistics, NOC contacts, replacement logic, and technical documents for first deployment.
Each package starts from the same engineering inputs: required data rate (10G to 800G), reach in metres or kilometres, fiber type (OS2 single-mode or OM4 multi-mode), wavelength plan (1310 nm grey, 1550 nm DWDM C-band, or 100 GHz ITU-T G.694.1 grid), and the host platform's QSFP-DD or OSFP port profile. Finisar runs the dB power budget against the worst-case insertion-loss stack (connector, splice, dispersion, BER margin) and flags any hop that needs a dispersion compensation module, an EDFA boost, or a step up to coherent ZR+. Sample units arrive paired with S-parameter touchstone files, ORAN 7.2x compliance notes, and a ready BER and PIM acceptance template, so the first lab burn-in is the same gate the carrier will use for production sign-off.
Onboarding finishes with a written handoff to the NOC: spare optic count by SKU, MTBF projections, RMA escalation path, and a labelled patch schedule mapped to the ODF and switch fabric. That paperwork is what turns a successful pilot into a repeatable rollout across additional metro rings, FTTH OLT shelves, or 400G fabric pods.
Send the route, traffic target, product category, and deployment date. Finisar will respond with the next engineering questions and a practical BoM path.
