Low loss PON splitter
G657A2 Low Loss PON Fiber Optic Splitter 2×8
This G657A2 low loss PON fiber optic splitter is a passive planar lightwave circuit (PLC) device that splits optical power from two inputs to eight outputs without requiring external power.
It offers a wide splitting portfolio from 1(2)×2 up to 1(2)×64, maintaining stability over temperature and wavelength with low insertion loss, low input polarization sensitivity, excellent uniformity, and low return loss.
The splitter is available in small form factor nickel‑copper blockless packages, ABS box modules, and cassette (slot‑in) types, and can be supplied with various fan‑out configurations and pre‑terminated SC/FC/ST/LC APC or UPC connectors.

Key Benefits
1. Optimizes PON/FTTx
network performance by combining low loss, low PDL, and high uniformity in a compact passive device.
2. Simplifies deployment
in FTTx cabinets, ODFs, and closures thanks to small footprint and multiple packaging options.
3. Reduces maintenance
and replacement costs due to robust environmental and mechanical stability.
4. Supports multiple application
scenarios including FTTB/FTTH/FTTC, PON, LAN, and test equipment with a single splitter platform.
