Description

Class B+ GPON OLT SFP transceiver delivering 2.488 Gbps downstream and 1.244 Gbps upstream over single‑fiber with 1490/1310 nm wavelengths. Suitable for ODNs up to 20 km with typical split ratios supported by B+ optical budgets.

Features

- B+ optical budget for mainstream GPON deployments
- BiDi single‑fiber operation reduces cabling
- Standards‑compliant interop with GPON ONTs
- DOM support for optical health monitoring
- Up to 20 km ODN coverage (design-dependent)

FAQs

Q: Is this an OLT or ONU module?
A: This is an OLT GPON SFP. It plugs into an OLT-capable port on your platform and serves multiple ONUs/ONTs via the ODN.

Q: What split ratios are supported?
A: Split ratio depends on total optical loss. Class B+ budgets commonly support up to 1:64 under typical ODN designs.

Q: Will it interoperate with Class C+ ONTs?
A: Yes, class interop is possible if the overall ODN budget is within limits and the OLT platform supports it.

Q: What connector type should I patch with at the ODN?
A: The module uses LC on the transceiver; adapt as needed to your ODN connector type (often SC/APC) via appropriate patching.
