    摘要： An optical connector includes a base member having a first hollow bore extending from a first end toward a second end, and a recess coaxially aligned with the first hollow bore. The recess has a first internal perimeter and a second internal perimeter. The first perimeter is smaller than said second perimeter. The base member can have a post extending up from a bottom of the recess. The first hollow bore passes through the past and terminates at an end of the post. The post can have an end that terminates substantially in alignment with at least a portion of a termination region disposed between the first internal perimeter and the second internal perimeter.

    摘要： Systems and methods are disclosed measuring the turn-on and turn-off times of an optoelectronic transceiver's transmitter circuitry. The method includes generating a two bit sequences from separate bit sequence generators using the same controlling pattern. The first bit sequence is transmitted through an optoelectronic device and compared with corresponding bit groups in the second bit sequence. The optoelectronic device is disabled and a count of compared bit groups is kept until the comparison indicates that the optoelectronic device is completely off. Using the count and one or more of the bit groups, a turn-off time is calculated. Alternatively, the method is used to calculate a turn-on time. The optoelectronic device is enabled and a count is kept from the time the device is enabled to when the comparison of the corresponding bit groups indicates that the optoelectronic device is completely on.

    摘要： A receive optical subassembly comprises a header assembly positioned inside an outer shell that interfaces with a receive optical fiber. The header assembly comprises an upper surface upon which one or more optical components can be mounted, the upper surface defined at least in party by a standard plane. The header assembly further comprises an angled surface that is angled with respect to the standard plane. The angled surface can comprise, for example, a sloped cavity stamped inside the header assembly, or an angled shim positioned on top of the header assembly upper surface. An optical receiver mounted on the angled surface receives an incoming optical signal but reflects at least a portion of stray optical signals away from the incoming optical signal.

    摘要： Method and apparatus of attenuating an optical signal without adding extra components is presented. The drive current of the optical signal source is set to meet a predetermined bandwidth requirement and exceed a predetermined amplitude requirement. An optical isolator that is used to prevent back-reflections from reaching the optical signal source is used to achieve the desired amount of attenuation. More specifically, the invention includes controlling the attenuation by tuning an angle θ between the transmission axis of a polarizer that is part of the optical isolator and the original polarization state of the optical signal. By increasing the angle θ, the amount of attenuation is increased; by decreasing the angle θ, the amount of attenuation is decreased. The invention allows continuous tuning of the angle θ.

    摘要： A system and method for testing the jitter tolerance and signal attenuation tolerance of an optoelectronic device is disclosed. The system includes a generation circuit, delay circuit and comparison circuitry. A first sequence of bits is generated, delayed, and sent to the optoelectronic device. The optoelectronic device receives the bits and retransmits them as a second sequence to the comparison circuitry, which compares the two bit sequences to determine a bit error rate. The bit error rate is then used to determine the jitter tolerance and, in an alternate embodiment, the signal attenuation tolerance of the optoelectronic device being tested.
