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. OM3/OM4 multimode fiber is optimized for short, high-density links, typically in data centers. These modules are extensively used in 100Mbps Ethernet, Gigabit Ethernet, 1G/2G fiber channel, and synchronous optical networks (SONET/SDH). This product is already in your quote request list.
