Upper limit of light reception for 80km 100Mbps optical modules
For links up to 80 km without amplification, the modules ZR/ER 1550 nm offers the best ranges. The Elfcam range includes 40G ZR4 (80 km) and 25G LR (80 km) modules compatible with major switch brands (Cisco, Arista, Mellanox, HPE, Juniper). An SFP (Small Form-factor Pluggable) module transmits data over fiber using specific wavelengths and power levels, which directly influence how far the signal can travel before degradation occurs. This is why two modules with the same form factor can have dramatically different ranges—some limited. For inter-site links between 15 and 80 km, 1550 nm modules are therefore preferable to standard 1310 nm modules.

100M optical module light receiving sensitivity
Receive sensitivity defines the minimum optical power required to maintain an acceptable bit error rate (BER ≤ 1E-12) at specific data rates. This parameter depends on multiple technical factors including photodetector type (PIN/APD) and transimpedance amplifier (TIA) noise. When it comes to evaluating the performance of an optical transceiver, two key factors come to the fore: Output power (TX Power) and Receiver Sensitivity (RX Sensitivity). An understanding of these concepts is pivotal to establishing an effective and efficient optical network. It specifies a module's capability to perform in harsh environments and helps network operators determine the maximum reach or link margin available in the system. For example, SONET specifies that the BER must be 10 -10 or better.
