Title: Optical communication network
Inventor: REONARUDO JIYOOJI KOOEN
IPC: H04B10/272
Filed: 1992-12-14
Abstract: PURPOSE: To provide an optical communication network in which a coupling loss is not deteriorated. CONSTITUTION: This optical communication network is provided with a primary fiber 10 for operating transmission between a distribution node and a telephone station, plural distribution fibers(DF) 50 terminated at an optical network unit(ONU) 40 for operating transmission between the ONU 40 and a node 30, and optical coupler 60 in the node 30. Also, this ONU 40 is provided with a monitor 70 which receives transmission including diagnostic information and a by pass line(BL) 90 passing through one part of transmission from the DF 50 to the monitor 70 without passing through the coupler 60. Also, this ONU 40 is provided with a passive comportment (PC) for physically labeling the transmission in the BL 90 so that the diagnostic information can be assigned to each DF 50.  This label is operated by assigning time delay, monitor wavelength, or the combination of the time delay and the wavelength to each DF 50. Thus, monitored transmission coupling loss can be saved for the normal network, and each DF 50 can be identified by purely using a PC.

Abstract: PROBLEM TO BE SOLVED: To obtain a sheet which is used for printing with a water-base ink and does not exhibit any change in physical properties, adhesiveness, and deliquescence even at high temp. and humidity by forming a water-base-ink absorption layer comprising a high-mol.-wt. polydioxolane on the surface of a thermoplastic resin substrate. SOLUTION: This sheet is obtd. by forming a water-base-ink absorption layer comprising a high-mol.-wt. polydioxolane represented by formula II and obtd. by polymerizing a 1,3-dioxolane monomer represented by formula I on at least one side of a substrate comprising a thermoplastic resin. The obtd. sheet is excellent in stability and resistances to humidity and water at high temp. and humidity, though having a high hydrophilicity, esp. a high solubility in warm water. Even when the sheet has absorbed moisture, it does not exhibit any change in physical properties (e.g. clarity of gloss), adhesiveness (e.g. stickiness or blocking), deliquescence, and blur of a printed water-base ink, thus exhibiting an excellent storage stability.
