Encapsulation type: eSFP
Transmission distance: ≤ 80 km
Fiber type: single-mode, LC
Standard: CWDM
Operating temperature: 0°C to 70°C
NOTE
The operating temperature cannot exceed 45°C when CWDM optical modules are used
on the S2750-28TP-EI-AC.
l Transmit power: 0 dBm to 5.0 dBm
l Receiver sensitivity: ≤ -28.0 dBm
l Overload optical power: -9.0 dBm
l Extinction ratio: ≥ 8.5 dB
NOTE
The appearance of CWDM and DWDM optical modules is similar to that of common optical modules.
These optical modules are distinguished by their labels. In practice, the corresponding optical fibers are
labeled to distinguish the optical modules.
