D-LINK DMC-920R Converter
Availability: In Stock
DescriptionThis media converter combines transmit and receive signals onto one fiber strand using two wavelengths. This design avoids the budget losses incurred by the single-wavelength single-fiber technology, and minimizes the possibility of reflections in the system. The units on both ends of a link are different. One module uses one wavelength to transmit and a second wavelength to receive, while the other module flips that relationship. For this reason these units are used in pairs.A pair of one-channel single fiber is used for media conversion between 10/100BASE-TX and 100BASE-FX.Two differ ent transmitting wavelengths, one wavelength with bi-directional for both transmit and receive.- DMC-920R: This media converter provides 1310 micron for TX, 1550 micron for RX.- DMC-920T: This media converter provides 1550 micron for TX, 1310 micron for RX.Fiber cable support is 9/125um, 10/125um single-mode fiber , maximum 20 km cable distance.General featuresInterfaceNumber of Ports• 1 x 1000BASE-T RJ-45 port• 1 x 1000BASE-LX bidirectional SC portStandards• IEEE 802.3ab for 1000BASE-TX• IEEE 802.3z for 1000BASE-LXData Transfer Rate• 2000 Mbps (full-duplex)Duplex Mode• Full-duplexMedia Types• 1000BASE-T: 4-pair Cat. 5, Shielded Twisted Pair (STP) (up to 100 m)• 1000BASE-LX: Single-mode fiber optic cable with SC connector (up to 10 km)Media Exchange Interface• Auto-MDI/MDIXFunctionalityTransmission Mode• Store-and-forwardForwarding Rate• Full wire-speed forwarding rateManagement• Through the DMC-1000 chassis with the DMC-1002 management module installedManagement Functions• LLR (enable/disable)• Fiber modePhysicalDiagnostic LEDs• Power• LINK/ACTAC Input• 5 V/1 A external power adapterTemperature• Operating: 0 °C to 40 °C (32 °F to 104 °F)• Storage: -10 °C to 70 °C (13 °F to 158 °F)Humidity• 10% to 90% RH, non-condensingDimensions• 120 x 88 x 25 mm (4.72 x 3.46 x 0.98 in)Weight• 300 g (0.66 lbs)Fiber Wavelength• TX: 1310 nm• RX: 1550 nmSupported Fiber Cable Length• Up to 10 kmEmission Certifications (EMI)• FCC Class A• VCCI Class A• CE Class A
