1550nm Narrow Linewidth Laser
Output Power up to 60mW Linewidth as low as 60KHZ
Output Power up to 60mW Linewidth as low as 60KHZ
Using DFB laser chip and butterfly package "Standard ITU wavelength spacing reduces the equipment requirements of hubs and wide temperature range ensures stability in harsh environments" "Meets Telcordia GR-468-CORE standards and RoHS requirements covering DWDM bands"
These singlemode 1550 nm laser diodes can reach high power in nanosecond pulse regime up to 500 mW. Most Turn-key diode + driver solutions are optimized from single-shot to CW performances with pulse width lengths down to 1 nanosecond. The 1550nm laser diode precision pulses are generated internally by an on-board pulse generator, or on demand from an external TTL signal. It becomes easy to generate complex burst shapes.
ORTE7151-CXX-X is a Dense Wavelength-Division Multiplexing(DWDM)laser for analog applications.It features a distributed feedback chip for Ratio Frequency(RF) applications,and is available in a wide range of standard ITU wavelengths.The lasers are offered as either forward-path (40MHz – 860MHz) or return-path ( 5MHz – 200MHz) modules.
The 1X2 wavelength division multiplexer and isolator hybrid device (1X2 IWDM) can be used in EDFA with high isolation requirements, which can not only ensure the optical isolation to meet the requirements, but also reduce the size of the entire EDFA module. Pump light can also be injected into an Erbium-doped fiber (EDF) from port 2 of the fiber to act as an optical amplifier. IGFF combines an optical isolator with a gain flattening filter (GFF) to create a device that does both and can be scaled down. The optical isolator functions as described above to block reverse optical input. A filter can be added behind the optical isolator core. When the film is plated on the filter, the transmission spectrum is just complementary to the transmission spectrum gain of the isolator core, that is, it plays the role of gain flattening. This optical passive hybrid device, mainly used in EDFA and Raman amplifiers, has small size, accurate gain distribution matching, optical path non-adhesive and ROHS standard compatibility.
