 产品描述(Description):

1000Base SFP 千兆以太网光模块主要应用在Gigabit Ethernet千兆以太网, Fibre Channel光纤通道, Optical Supervisory Channel OSC等领域,是目前交换机,路由器等网络设备主流的光模块产品。 100Base SFP 百兆光模块主要应用在FAST Ethernet快速以太网。产品符合SFP MSA,IEEE802.3标准与光纤通道FC-PI-2Rev.7.0标准。该款产品通过与光纤协同工作,为数据通讯提供完整的双向数据链路连接,实现数据信息的高速、透明转发。 

HE-LINK Copper Small Form Pluggable (SFP)transceivers is high performance, cost effective module compliant with the Gigabit Ethernet and 1000- BASE-T standards as specified in IEEE 802. 3-2002 and IEEE 802.3ab, which supp- orting 1000Mbps datarate up to 100 meters reach over unshielded twisted-pair category 5 cable. The module supports1000 Mbps full duplex data-links with 5-level Pulse Amplitude Modulation (PAM) signals. All four pairs in the cable are used with symbol rate at 250Mbps on each pair. The module provides standard serial ID information compliant with SFP MSA, which can be accessed with address of A0h via the 2wire serial CMOS EEPROM protocol. The physical IC can also be accessed via 2wire serial bus at address A0h.
