The practical transmission range of an electrical cable can be extended by converting between electrical and optical signals using an HDMI-optical converter that receives an SFP+ optics transceiver. A pair of SFP+-based HDMI adapters/extenders can connect to a pair of HDMI cables, where one of the HDMI cables is connected to an HDMI Source and one of the HDMI cables is connected to an HDMI Sink. Each of the SFP+-based HDMI cable extenders can terminate with an SFP+ port to house a hot pluggable SFP+ transceiver. The apparatus can transmit 10 G video data to the distance that is supported by the SFP+ product.

A converter apparatus is provided enabling conversion of data between different form factor pluggable standards. The converter comprises a first connector that connects to a first device according to a first form factor pluggable standard, and a second connector that connects to a second device according to a second form factor pluggable standard. The converter further comprises a signal processor coupled between the first connector and the second connector. The processor converts at least one of transmit signals in the first form factor pluggable standard to transmit signals in the second form factor pluggable standard and receive signals in the second form factor pluggable standard to receive signals in the first form factor pluggable standard. A controller in the converter is coupled to the processor and to the first and second connector. The controller configures the processor to be used for converting signals between the form factor pluggable standards.

An apparatus, in accordance with particular embodiments, includes an interface configured to establish connections within a copper network. The apparatus also includes a receptacle configured to receive a conventional small form-factor pluggable (SFP) module or a compact SFP module and to direct the SFP modules to a first connector. The first connector connects either of the SFP modules to the node. A pin of the first connector is configured to receive a module detection signal and to transmit data to the compact SFP module. The apparatus also includes a low pass filter coupled to the pin of the first connector that passes the module detection signal to the node. The apparatus is further configured to establish two duplex connections with an optical fiber network if the compact SFP module is connected and to establish one duplex connection with the optical fiber network if the conventional SFP module is connected.

An apparatus includes a transceiver device mounted on a printed circuit board and configured to selectively transmit and receive signals at a first data rate or signals at a second data rate. An X2 form factor pluggable connector disposed at one end of the printed circuit board includes first and second pins that respectively convey signals at the first and second data rates between the transceiver device and a system device. A port device disposed at an opposite end of the printed circuit board conveys signals between the transceiver device and a network device. A management circuit determines which of the first and second data rates is selected based on transmissions between the system device and the network device and controls the transceiver device to transmit and receive signal at the first data rate via the first pins and at the second data rate via the second pins.

Adaptive power setting techniques for optical transceivers are provided. Optical signals are received at a first optical transceiver device that are transmitted from a second optical transceiver device. A receive power of the optical signals received at the first optical transceiver device from the second optical transceiver device is determined. A characteristic of optical signals transmitted by the first optical transceiver device to the second optical transceiver device is modulated to indicate to the second optical transceiver device a disparity of the receive power with respect to a target receive power level at the first optical transceiver device. Conversely, the first optical transceiver device adjusts a power level of optical signals transmitted by the first optical transceiver device to the second optical transceiver device based on a characteristic of the optical signals received at the first optical transceiver device.
