25G 850nm 多模SFP28有源光缆 - 北亿纤通|F-tone Networks-全球光芯片光器件光模块光通信系统产品领导者!

Description
F-tone Networks SFP28 Active Optical Cables are direct-attach fiber assemblies with SFP28 connectors. They are suitable for very short distances and offer a cost-effective way to connect within racks and across adjacent racks.
The F-tone Networks FTCS-25G-CS-Oxxx is a single-Channel, Pluggable, Fiber-Optic SFP28 for 25 Gigabit Ethernet and Infiniband EDR Applications. It is a high performance module for short-range data communication and interconnect applications which operate at 25.78125 Gbps up to 70 m using OM3 fiber or 100 m using OM4 fiber without FEC ,or 300m using OM4 fiber with FEC. This module is designed to operate over multimode fiber systems using a nominal wavelength of 850nm. The electrical interface uses a 20 contact edge type connector.

Features
● Hot-pluggable SFP28 form factor
● Supports 25Gbps data rate
● Maximum link length of 70m on OM3 MMF and 100m on OM4 MMF without FEC, or 300m om OM4 MMF with FEC
● 850nm VCSEL laser and PIN photo-detector
● Internal CDR on both Transmitter and Receiver channel
● Single 3.3V power supply
● Power dissipation < 1W
● Digital diagnostics functions are available via the I2C interface(Optional)
● RoHS 2.0 compliant
● Case operating temperature
Commercial: 0 ~ +70℃
Industrial: -40 ~ +85℃

Applications
● 25GBASE-SR Ethernet
