WB170
Compact 3G 1RU Transport SDI and Multi Format Interface
Description
Compact 3G 1RU Transport SDI and Multi Format Interface The WB170 is designed as an ultra compact 19” rack-mount media converter for the conversion of up to 32 independent 3G-SDI, HD-SDI, SD-SDI and ASI signals into fibre optical cable. The WB170 fits applications where space is at a premium but no compromises on the broadcast performance can be accepted. Applications
- Studios requiring 3G/HD links to main CAR and with wall mounting capability Integration with existing routing/equipment infrastructure to provide multiple fibre I/O
- Low cost and high density distribution
- Remote ingest points and tie-lines between OB vans and Studios
The WB170 can be populated with WB172 transmitter or receiver cards or the Multi Format WB172-63 SFP cards. All cards are inserted from the front of the frame. Each incoming signal on a WB172T is auto-sensed, equalised and then reclocked prior to conversion and transmission down a separate single optical fibre. The WB172R is the corresponding receiver for the conversion of two independent optical signals into electrical 3G-SDI, HD-SDI, SD-SDI and ASI. The incoming optical signal is fed to a trans-impedance and limiting amplifier before being electrically reclocked on the outputs. The WB172 is available in multimode, singlemode, WDM and CWDM variants to suit any fibre application. The WB172-63 and WB172-63TR provide a base unit that comprises two SFP cages. By using different SFP converter modules the functionality of the unit can be adapted to suit different applications. Multi format SFPs include conversion to and from Composite, HDMI, DVI, optical and SDI. Units can also be used for regenerating optical signals from multimode to singlemode or re-mapping wavelengths within existing fibre systems.
