Optical Isolators Specifications

Help with Optical Isolators specifications:

Isolator Type

	Your choices are...
	Inline Isolator		An isolator with pigtail and connectors that can be integrated effectively into a fiber optic system.
	Free Space Isolator		An isolator with no connectors that is mounted in some manner to the object in need of isolation.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
	Connector Type:
	Your choices are...
	Biconic		Biconic connectors have precision tapered ends for low insertion loss.
	D4		D4 connectors contain composite zirconia ceramic ferrules for durability. They feature a high-performance threaded mounting system and a keyed body for repeatability and intermateability.
	ESCON		ESCON connectors derive their name from their original application, IBM's enterprise system connection (ESCON) for mainframe computers. ESCON connectors are similar to FDDI connectors, but contain a retractable shroud instead of a fixed shroud. ESCON connectors have two 2.55 mm ceramic ferrules and a robust strain relief design.
	FC		FC connectors have an all-zirconia ceramic ferrule for durability, a high-performance threaded mounting system, and a keyed body for repeatability and intermateability. FC connectors are used primarily with single mode fibers and in telephone, instrumentation, and high-speed communication links.
	FDDI		Fiber distributed data interface (FDDI) connectors are designed for use in FDDI networks, a LAN technology that uses dual, counter-rotating 100-Mbps fiber optic rings. FDDI connectors are duplex devices that contain two 2.5 mm ferrules. A fixed shroud protects the ferrules from damage.
	LC		LC connectors include a polished, zirconia ceramic ferrule and a push / pull-style housing with a latching mechanism. LC connectors are half the size of standard fiber optic cable connectors. They are suitable for both public and private networks.
	Loopback		Loopback connectors are used to test transceiver systems.
	MTP		MTP connectors are threaded and well-suited for high density applications.
	MT-RJ		Unlike other fiber optic connectors, MT-RJ connectors hold two fibers with a single ferrule. MT-RJ connectors are a variation of MT connectors, but use a smaller ferrule.
	MU		MU connectors contain a ferrule with a diameter of 1.25 mm. Applications include high-speed data communications, voice networks, telecommunications, and dense wavelength division multiplexing (DWDM). MU connectors are also used in multiple optical connections and as a self-retentive mechanism in backplane applications.
	SC		Subscription channel (SC) connectors are coaxial, medium-size devices with a constant 50Ω impedance and a frequency range of 0 - 11 GHz. They are larger than BNC connectors, but about the same size as Type N devices.
	SMA		Subminiature-A (SMA) connectors are intended for use on semi-rigid cables in components. They directly interface the cable dielectric without air gaps.  SMAs are not intended for permanent connections.
	ST		Straight tip (ST) connectors use a quick release, bayonet coupling that requires only a quarter turn to engage or disengage. Built-in keying provides repeatable performance because ST connectors always mate with a coupling bushing in the same way. ST connectors are used in FDDI cabling applications.
	Other		Other unlisted fiber optic connectors.
	Search Logic:		Products with the selected attribute will be returned as matches. Leaving or selecting "No Preference" will not limit the search criteria for this question; products with all attribute options will be returned as matches.

Isolator Performance

	Center Wavelength:		The wavelength the isolator is designed for.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
	Isolation:		A measure of how effectively back reflections are prevented to how well the isolator transmits.
	Search Logic:		All matching products will have a value greater than or equal to the specified value.
	Insertion Loss:		The attenuation caused by the insertion of an optical component.
	Search Logic:		All matching products will have a value less than or equal to the specified value.
	Polarization Dependent Loss:		The attenuation caused by polarization.
	Search Logic:		All matching products will have a value less than or equal to the specified value.
	Aperture:		The size of the isolator opening through which light passes.
	Search Logic:		All matching products will have a value greater than or equal to the specified value.
	Maximum Power:		The maximum output power the isolator can handle.
	Search Logic:		All matching products will have a value greater than or equal to the specified value.

Environment

	Operating Temperature:		This is the full required range of ambient operating temperature.
	Search Logic:		User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria.
