Description
The F-tone Networks FTQ2-HG-SR4I-CPRI is a Four-Channel, Pluggable, Fiber-Optic SQFP28 for 4*24.33 Gigabit 5G eCPRI QSFP28 SR4（Industrial Grade）Applications. This transceiver is a high performance module for short-range multi-lane data communication and interconnect applications.Each lane can operate at 24.33Gbps up to 70 m using OM3 fiber or 100 m using OM4 fiber. These modules are designed to operate over multimode fiber systems using a nominal wavelength of 850nm. The electrical interface uses a 38 contact edge type connector. The optical interface uses an 12 fiber MTP (MPO) connector. This module incorporates F-tone Networks proven circuit and VCSEL technology to provide reliable long life, high performance, and consistent service.
