GTTD-ZZ1G(1.25G單纖）
GTT TELECOM生產(chǎn)的SFP光纖模塊（1.25Gigabit Small Form Factor Pluggable）是一種可熱插拔的，獨(dú)立于通信協(xié)議的光學(xué)收發(fā)器，通常傳輸光的波長是 850nm, 1310nm 或1550nm，用于1.25G bps的SONET/SDH，光纖通道，gigabit Ethernet，10 gigabit Ethernet和其他應(yīng)用中，也包括 DWDM 鏈路。
光模塊按照封裝形式和速率等分類，常見的有SFP，1X9,SFP+,XFP，QSFP,CFP,GBIC,CXP,CFP2,CFP4,CWDM和DWDM系列等等。GTT TELECOM生產(chǎn)的光模塊種類齊全，穩(wěn)定性高，兼容能力強(qiáng)，遠(yuǎn)銷海內(nèi)外，具有較好的聲譽(yù)。

Descriptions
Small Form Factor Pluggable (SFP) transceiversare compatible with the Small Form Factor Pluggable Multi-Sourcing Agreement (MSA),The transceiver consists of sections: the LD driver, the limiting amplifier, the digitaldiagnostic monitor.
The optical output can be disabled by a TTL logic high-level input of Tx Disable,ａnd the system also can disable the module via I2C. Tx Fault is provided to indicatethat degradation of the laser. Loss of signal (LOS) output is provided to indicate theloss of an input optical signal of receiver or the link status with partner. The systemcan also get the LOS (or Link)/Disable/Fault information via I2C register access.
