Estimate fiber link loss, remaining optical margin, and pass / warning / fail status for data center, FTTH, ODN, MPO/MTP and PON projects. Use it before ordering fiber optic cable, patch cord, pigtail, adapter, attenuator, PLC splitter, termination box or ONU-related products.
Use real project values where possible. Default assumptions can be adjusted below.

After calculation, copy this checklist and send it with your project inquiry. It helps ZION confirm fiber type, connector type, link length, polarity, splitter ratio and test report requirements before quotation.
RFQ checklist will be generated after calculation.
The result below helps buyers and engineers identify which product details should be confirmed before quotation or sample preparation.
Use stable LC / SC / FC / ST connector geometry, clean end-face control and test report confirmation.
For high-density links, confirm low-loss grade, polarity method, pin type and 100% test results.
For FTTH / PON, splitter ratio, uniformity, connector type and package style strongly affect link margin.
For indoor FTTH, tight routing and termination box applications, bend-insensitive fiber can reduce field risk.
To receive a more accurate quotation, buyers should define not only the cable type, but also connection structure, polarity, test requirement and packaging.
It is the total allowable optical loss between transmitter and receiver. It includes fiber attenuation, connectors, splices, MPO/MTP connections, splitter loss, attenuator loss and engineering reserve.
PLC splitters divide optical power into multiple outputs. In many PON links, splitter loss is much higher than fiber attenuation or connector loss, so it often determines whether the link margin is acceptable.
Low-loss MPO/MTP is recommended for high-density data center links, multiple cassette transitions, 40G / 100G / 400G cabling, or any link with limited optical budget.
Yes. G.657.A2 bend-insensitive fiber is useful for indoor FTTH, termination boxes, compact routing, wall outlets and areas where small bending radius may increase field loss.
Send ZION your fiber type, connector type, length, splitter ratio, MPO polarity and test report requirement. Our team can support cable, patch cord, pigtail, adapter, attenuator, PLC splitter, ODN and FTTH product selection.
