Product Details
The SFP+ DWDM 40KM transceiver comprises three main components: a cooled EML laser transmitter, a PIN photodiode integrated with a trans-impedance preamplifier (TIA), and an MCU control unit. All modules meet Class I laser safety standards. These 10G DWDM 40KM transceivers are compatible with the SFP Multi-Source Agreement and support the SFF-8472 digital diagnostics functions. The 10G SFP+ DWDM C21 40KM modules find extensive application in 10Gbps DWDM optical systems, specifically 10GBASE-ZR operating at 10.3125Gbps, 10GBASE-ZW operating at 9.953Gbps, LTE systems, and other optical links.

FAQ
1. What cable is used for SFP+?
A: SFP + cable is a high speed cable with SFP+ connector modules at both ends. It uses the connector to transmit and receive data for 10Gbps.
2. What is the voltage of SFP+?
A: The DC impedance of SFP+ inductance should be less than 1 ohm to ensure that the supply voltage of SFP+ is stable at 3.3V.
