KTX-485-D3AA

NEW PRODUCT 2.5Gbps VCSEL TOSA KTx-485-D3AA Description VCSEL module, TOSA(Transmitter Optical Sub Assembly) consists of reliable 850nm VCSEL, back monitor PIN PD and plastic SC or LC receptacle. The power monitor PD can be used with appropriate feedback control circuitry to set a constant power level for each VCSEL. The parts of plastic SC or LC receptacle are actively aligned. This module guarantees high coupling efficiency, high slope efficiency, low operating current and low tracking error over wide temperature range(0℃ to +85℃) and provides high optical performance.
