10Gbps 1310nm 20km LC SFP+
The SFP+ transceivers are high performance, cost effective modules supporting data rate of 10Gbps and 20km transmission distance with SMF. The transceiver consists of three sections: a DFB laser transmitter, a PIN photodiode integrated with a trans-impedance preamplifier (TIA) and MCU control unit. All modules satisfy class I laser safety requirements. The transceivers are compatible with SFP Multi-Source Agreement and SFF-8472 digital diagnostics functions.

What is the difference between SFP and SFP+ 10G?
SFP and SFP+ are both small form-factor pluggable transceivers used in networking equipment for transmitting data over fiber optic cables. The main difference between the two is their speed.
SFP modules have a data rate of up to 1Gbps, while SFP+ modules have a data rate of up to 10Gbps. This means that SFP modules are typically used for slower connections such as 10/100/1000 Ethernet, while SFP+ modules are used for higher speed connections such as 10 Gigabit Ethernet.
Another difference is that SFP modules are typically used for shorter distances, while SFP+ modules can be used for longer distances. SFP modules are designed for distances of up to 550 meters over multi-mode fiber and up to 10 kilometers over single-mode fiber. SFP+ modules, on the other hand, can transmit data over distances of up to 40 kilometers over single-mode fiber.
In terms of physical size, SFP and SFP+ modules are almost identical, with the main difference being the number of electrical contacts. SFP modules have 20 contacts, while SFP+ modules have 30 contacts.
