Fiber Optic Interface

Multimode ports are labeled MM. Singlemode ports are labeled SM. Extended distance ports are labeled LH (Long Haul) or ELH (Extended Long Haul). Each fiber port provides an SC or LC connector. For informa- tion about the cable lengths supported by each model, refer to the table in the Technical Specifications section.

When making connections, be sure that the transmit (TX) optical conductor of the “twister” connects to the receive (RX) optical conductor of the connected device; and be sure that the transmit (TX) optical conductor of the device connects to the receive (RX) optical conductor of the “twister”.

Once power is applied to the unit, correct connectivity can be verified via the LINK LED.

BWDM Interface

The bidirectional wavelength division multiplexed (BWDM) port provides one singlemode SC connector that supports a maximum segment length of 20km. BWDM units must always be used in complementary pairs. That is, a -1X or -AX must be connected to a -1X or -AY. The -1X and -AX units are designed to transmit data at a wavelength of 1550nm and receive at 1310nm. Correspondingly, the -1Y and -AY units transmit data at 1310nm and receive at 1550nm.

5Apply Power

Power is applied to the “twister” from the desktop power supply. The power supply is equipped with an S760 hollow-type plug for insertion into the DC jack located on the back of the unit and the standard IEC 320-type AC power receptacle. All standalone units use a 100-240V universal desktop power supply.

Connect the DC input jack located on the back of the “twister” before connecting to the AC outlet.
