Optical Spectrum Analyzers Specifications

Help with Optical Spectrum Analyzers specifications:

Test Equipment Type

	Form Factor
	Your choices are...
	Bench Top		The optical spectrum analyzer is the larger bench top type.
	Hand Held		The optical spectrum analyzer is portable.
	Rack Mount		The optical spectrum analyzer is rack mountable.
	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.
	Cable Type:
	Your choices are...
	Single-mode		Single-mode optical fibers will allow only one mode to propagate. The fiber has a very small core diameter of approximately 8 µm. It permits signal transmission at extremely high bandwidth and allows very long transmission distances.
	Multimode		Multimode fiber optic cables support the propagation of multiple modes. Multimode fiber may have a typical core diameter of 50 to 100 µm with a refractive index that is graded or stepped. It allows the use of inexpensive LED light sources and connector alignment and coupling is less critical than single mode fiber. Distances of transmission and transmission bandwidth are less than with single mode fiber due to dispersion.
	Single-mode / Multimode		Multiplexer can be used with both single mode and multimode cable types.
	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 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. They 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.

	Search Logic:		All matching products will have a value less than or equal to the specified value.
	Optical Power Range:		The detection power range of the fiber identifier.
	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.
	Dynamic Range:		The ratio of the maximum to minimum power level of an optical signal.
	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.
	Return Loss:		Return loss is the ratio (expressed in units of dB) of optical power reflected by a component or an assembly to the optical power incident on a component port when that component or assembly is introduced into a link or system.
	Search Logic:		All matching products will have a value less than or equal to the specified value.
