10G/25G SFP28 Narrow Band Tunable |

Raytel 10G/25G SFP28 narrow band tunable series transceivers are designed for 5G front haul application , with the low cost and high quality performance . The transceiver is incorporated with a narrow band tunable laser (with 6/12 channels tuning range ) and APD-TIA receiver, which is suitable for the high link budge networks. The 10G SFP+ tunable products can be up to 20km reach , the 25G SFP28 tunable products can be up to 10km reach without dispersion compensation in fiber . The Operation Administration and Maintenance (OAM) function, which is meet G.698.4(G.metro) standard ,can be implemented to the transceivers and very helpful for managing the remote units .There are LC bi-directional and LC duplexer receptacle types available .
Key Features:
• C-band 6 / 12 Channels Tunable with 100GHz Spacing
• With / Without G.698.4 OAM Function
