摘要： Systems and methods for performing closed-loop diagnostics in optical transceiver. The TOSA of an optical receiver includes a primary transmit module and a secondary receiver module. The transmit module transmits a data signal to a ROSA of another optical transceiver. The ROSA has a secondary transmit module that can transmit a diagnostic data signal back to the secondary receiver module of the TOSA. The TOSA can use the diagnostic data received from the ROSA to automatically adjust itself and perform closed-loop feedback functions. The closed loop diagnostics can be implemented in a network where one transceiver may be connected with more than one other transceiver in a multi-node configuration.

摘要： An optoelectronic device uses microcode to perform an end of life calculation for the optoelectronic device. In a disclosed example, the optoelectronic device senses environmental and operational parameters under changing conditions during device operation. The optoelectronic device then calculates the end of life for itself based on one or more of the sensed environmental and/or operational parameters. The calculation can be done in real time and using digital logic. The calculation can provide a result in a format which is useful to a host system with which the device is connected. The optoelectronic device may automatically shut itself down upon reaching its calculated end of life.

摘要： An optical transceiver module is authenticated in a host system. A host generates a data string and writes the data string to a first predetermined memory location known to the transceiver. The data string is cryptographically altered (either encrypted or decrypted) by the transceiver and written to a second predetermined memory location known to the host. The host retrieves the cryptographically altered data string and performs a complementary cryptographic operation (either a decryption or encryption, respectively) thereon, creating a resulting data string. If the resulting data string is equal to the data string written to the first predetermined memory location, the transceiver is authenticated. The host and the transceiver may switch roles, with the transceiver generating the data string, the host cryptographically altering it, and so on. The host encrypts data strings when the transceiver decrypts data strings, and vice versa.
摘要翻译：光收发模块在主机系统中进行认证。主机生成数据串并将数据串写入收发器已知的第一预定存储器位置。数据串被收发器加密地改变（加密或解密）并被写入主机已知的第二预定存储位置。主机检索加密改变的数据串并执行补码加密操作（分别是解密或加密），创建结果数据串。如果结果数据串等于写入第一预定存储器位置的数据串，则收发器被认证。主机和收发器可以切换角色，收发器生成数据串，主机加密地改变它等等。当收发器解密数据串时，主机会加密数据串，反之亦然。

摘要： A method of maintaining desirable optical performance of an optoelectronic apparatus at extreme temperatures is disclosed. At a first temperature, a first bias current at which the laser generates optical signals at a first level is determined. At a second temperature outside of a predefined range of the first temperature, a second bias current at which the laser generates optical signals at a second level is determined. If the second temperature is greater than the higher end-point temperature of the predefined range, the second predefined level is defined to be less than the first predefined level. If the second temperature is less than the lower end-point temperature of the predefined range, the second predefined range is defined to be greater than the first predefined level.

摘要： Systems and methods for validating a data link between two communication modules, such as optical transceiver modules configured for bidirectional optical communication, are disclosed. In one embodiment a method according to the invention includes a first optical transceiver module transmitting a first validation optical signal to a second optical transceiver module via an optical waveguide, such as an optical fiber, that physically interconnects both transceivers. The first validation optical signal is received by the second optical transceiver module, which lights an indicator light on its housing and returns a second validation optical signal to the first optical transceiver module. Upon receipt of the signal, the first transceiver lights its indicator light and enables data transfer to occur between both transceivers. In other embodiments, the validation signals can be encrypted or scrambled to authenticate the transceivers as legitimate devices, or can contain identifying or descriptive information regarding the transceivers.

摘要： An integrated reflecting and focusing structure for use in optical transmitters and receivers to redirect optical signals when an optoelectronic device of the transmitter or receiver is positioned in an off-center relationship with respect to an intended light path is disclosed. The integrated reflecting and focusing structure simplifies construction while reducing complexity of the device. In one embodiment, an optical subassembly is disclosed and includes a housing and an optical fiber that is coupled to the housing. An optoelectronic component, such as a laser diode, is positioned in the housing and is configured to produce a light beam. The subassembly further includes an integrated focusing and reflecting prism that serves as a means for simultaneously redirecting and focusing the light beam while in transit between the laser diode and the optical fiber. The focusing feature combined with redirection of the light beam obviates the need for a separate lens assembly.

摘要： This disclosure concerns methods for calibrating optical emitters. For example, one calibration method is employed in connection with an optical transceiver that includes a laser. A range of temperatures is defined that includes low end and high end temperatures. At a first temperature, within the range, a first bias current to the laser is adjusted until the laser generates an optical signal at a first predefined power level. At a second temperature outside the range, a second bias current to the laser is adjusted until the laser generates an optical signal at a second predefined power level. If the second temperature is greater than the high end temperature, the second predefined power level is defined as less than the first predefined power level, and if the second temperature is less than the low end temperature, the second predefined power level is defined as greater than the first predefined power level.
