Agiltron NanoSpeed™ Ultra-Fast NxM Fiber Optical Switch 10ns
(10ns rise/fall time, polarization insensitive, all wavelengths, bidirectional, up to 20W)
DATASHEET
Product Overview
The NS Ultra-Fast Series (NF) fiber optical switch is based on a patented electro-optical configuration featuring low optical loss, wide temperature operation, and polarization insensitivity. The NS fiber optical switch has ultra-high reliability and can continuously operate for over 25 years in a vibration environment (passed Telcordia and space qualifications). The switch is bidirectional and available with configurations of polarization-independent or polarization-maintain. The rise/fall time is intrinsically related to the crystal properties, and the repetition rate is associated with the driver. The NF Series switch is mounted on an electronic driver having a 5V TTL control signal SMA input and a DC power supplier. There are poor frequency response sections in which the on/off ratio does not meet the spec due to the device's mechanical resonances. The on/off ratio can be optimized for certain frequencies with requests.
The NS series switches respond to a control signal with any arbitrary timing with frequency from DC up to MHz. The switch is usually mounted on a tuned driver prior to shipping. The electrical power consumption is related to the repetition rate the switch is operated.
The dual-stage configuration increases the extinction ratio or cross-talk value.

Notes:
- [1] For 1x4, for 1x8 adds 1dB, for 1x12 adds 2dB, for 1x24 adds 3dB. Measured without connectors. Each connector adds 0.2 to 0.3dB.
- [2] ± 25nm, The typical cross talk is measured at DC-20kHz and may be degraded at a higher repeat rate.
- [4] The standard version is defined at 1310nm/1550nm. For the shorter wavelength, the handling is reduced. High power version has a fiber end beam expander, thus cost more.
- [5] The driver is optimized at a repeat rate >500kHz. The specs exclude a few resonant frequency points. The performance can be optimized at other frequencies.

[1]. Red Wavelength Bands are special orders. They use special crystals.
[5]. High-power connectors can ordered as special.
Red Color-marked is special order with a higher price and longer lead time.
Note: PM1550 fiber works well for 1310nm, PM1310 fiber choice costs extra.
Application Notes
Fiber Core Alignment
The minimum attenuation for these devices depends on excellent core-to-core alignment when the connectors are mated. This is crucial for shorter wavelengths with smaller fiber core diameters that can increase the loss of many decibels above the specification if they are not perfectly aligned. Different vendors' connectors may not mate well with each other, especially for angled APC.
Fiber Cleanliness
Fibers with smaller core diameters (<5 µm) must be kept extremely clean. Contamination at fiber-fiber interfaces, combined with the high optical power density, can lead to significant optical damage. This type of damage usually requires re-polishing or replacement of the connector.
Maximum Optical Input Power
Due to their small fiber core diameters for short wavelength and high photon energies, the damage thresholds for the device are substantially reduced compared to the common 1550nm fiber. To avoid damage to the exposed fiber end faces and internal components, the optical input power should never exceed 20 mW for wavelengths shorter than 650nm. Agiltron produces a special version to increase the handling by expanding the core side at the fiber ends.
