200G QSFPDD LR8光模块

Description
The F-tone Networks FTQD-2H-LR8xx is an Eight-Channel, Pluggable, Fiber-Optic QSFP DD LR8 for 2×100 Gigabit Ethernet Applications. This transceiver is a high performance module for data communication and interconnect applications. It integrates eight data lanes in each direction with 208Gbps bandwidth. Each lane can operate at 26Gbps up to 10km over G.652 SMF. These modules are designed to operate over singlemode fiber systems using LAN-WDM 8 wavelengths. The electrical interface uses a 76 contact edge type connector. The optical interface uses duplex LC connector. This module incorporates F-tone Networks proven circuit and Optical technology to provide reliable long life, high performance, and consistent service.

Note：

• Even if the TDP < 1 dB, the OMA min must exceed theminimum valuespecified here.
• See Figure 4 below.
• The receiver shall be able to tolerate, without damage, continuous exposure to a modulated optical input signal having this power level on one lane. The receiver does not have to operate correctly at this input power.
• Measured with conformance test signal at receiver inputfor BER = 1×10^-12.
• Vertical eye closure penalty and stressed eye jitter are test conditions for measuring stressed receiver sensitivity. They are not characteristics of the receiver.
