摘要:
A laser driver IC has an RS flip-flop for latching a signal that indicates an event of fault detection, to output it as an internal fault signal, and a fault signal processing section for generating a disable signal for inactivating the driving function of the laser driver IC in response to output of the RS flip-flop. One of outputs of the fault signal processing section is connected to a fault signal output terminal linked to outside the laser driver IC.

摘要:
To provide a photoelectric composite wiring component combining both characteristics of low power consumption of transmission over electrical wiring and large transmission capacity of optical transmission over optical wiring, and exhibiting a high power efficiency for the transmission capacity. A mechanism for switching between transmission of a transmission signal over an electrical transmission path and that over an optical transmission path depending on the modulation rate or the transmission rate of the transmission signal is provided. When the modulation rate or the transmission rate of the transmission signal is low, power supply to an optical transmitting/receiving section is stopped and the signal is transmitted over the electrical transmission path, thus achieving low power consumption. When the modulation rate or the transmission rate of the transmission signal is high, the signal is transmitted over the optical transmission path, thus achieving a large transmission capacity.

An optical transceiver comprising a metal case, and an insulating film at least partially covering a case projecting from a host device when the optical transceiver is set in the host device. A method for coating the optical transceiver to be set in the host device comprises steps for sticking a tape to the receptacle portion with a silicone film of the case projecting from the host device when the optical transceiver is set in the host device, for stripping the tape after masking the part other than the receptacle portion, and for immersing the case entirely in a cation electrodeposition paint tank to form an insulating film composed of a cation electrodeposition coating film at the receptacle portion.

A package with a locking mechanism has: a package main body insertable into a cage formed in a host instrument; a package head integrated with the package main body; a latch member provided with the package main body, the latch member restricting detachment of the package main body from the cage when it is inserted into a hole formed in a wall of the cage and it is at a contact plane thereof in contact with a front edge of the hole while protruding from a predetermined face of the package main body; and a revolving shaft disposed perpendicular to a direction in which the package main body is inserted into and detached from the cage, the latch member being pivoted on the revolving shaft. The revolving shaft is disposed near the contact plane of the latch member.
