12.5Gb/s 1590nm光发射机 This Lightwave Transmitter is a high performance digital lightwave transmitter designed for optical communications up to 12.5 Gb/s bandwdiths. It has an internal L-bａnd 10mW DFB laser, a 13.5GHz Lithium Niobate (LN) Mach-Zhender Modulator, and an ultra-broadbａnd RF driver. Instead of the built-in DFB, users can also use an external tunable laser with the transmitter. It is compliant with standards such as OC-192, STM-64, and 10G Enet. Optical links can be established quickly with this product. | Technical Specifications | | Model Number | LT-1590-12.5G-B | | | | | Electro-Optic Specifications | | | | | | Modulation Format | 12.5Gb/s | | | | | Modulation Bandwidth | 15GHz minimum | | | | | Modulator Type | DFB + Lithium Niobate External Modulator | | | | | Input RF Voltage | > 0.5Volt p-p | | | | | RF Return Loss, S11 | >15 dB @ 10GHz, >12 dB @ 15GHz | | | | | Optical Output Power | > 7dBm | | | | | Modulator Bias Mode | 15 VDC | | | | | Extinction Ratio | > 13 dB at 10Gbs, >23 dB at 500Mb/s | | | | | RF Impednace | 50Ohm | | | | | RF Drive Volatge Control | 2.0 - 7.5Volt p-p | | | | | Modulator Voltage Range | 7.0Volt p-p at 12.5Gbs | | | | | Rise/Fall Time | 40ps maximum | | | | | Optical Specifications | | | | | | Laser Type | DFB, 10mW | | | | | Laser Wavelength | 1570-1600nm, user select | | | | | Laser Power Level | 20mW | | | | | Relative Intensity Noise | | | | | | Side Mode Suppression Ratio Ratio | 40 dB typical | | | | | Optical Isolation | 30dB minimum | | | | | Environment / User Interface | | | | | | External Laser Input | Panda, FC/APC | | | | | RF Input Connector | SMA | | | | | Output Optical Connector | FC/APC | | | | | Polarization Extinction Ratio | | | | | | Output Fiber | SMF 28 | | | | | Display | LCD | | | | | Computer Interface | RS-232 | | | | | Control | Key lock switch, Laser ouput, Drive Voltage, Bias Control | | | | | Power Supply | 80-240VAC, 43-63Hz | | | | | Dimensions | 350(W)x250(H)x250(D) | | | | | Operation Temperature Range (C) | 0˚C to +40˚C | | | | | Storage Temperature Range (C) | -10˚C to +70˚C | | | | | | | | | | | | | | | |
