ATEX Zone 1 Optical Transceiver

Request Number N177380
Need details
Description

Process Automation components are often installed into hazardous areas, such as ATEX Zone 1. To allow for distribution of communications technology such as PROFINET also in these areas, a suitable optical Transceiver is needed.

 

Background

System Ambient temperature -40°C … +70°C no fan

 

  • Operating temperature range: -40°C to + 85°C min., better to +95°C
  • Low Power consumption: e.g. 250mW (typ.) / 400mW (max.)
  • Wavelength: 1310nm
  • Fiber-Connector: LC for 50μm Multimode-Fiber (Distance up to 500m)
  • Operation in: Ex-Zone 1 (look at diagram above)
  • Availability of the Transceiver: 10 years min.
  • Diagnostics via I²C-Interface: TBD
  • Moisture proofing: e.g. PCBA coated for SFP, grouted for SFF
  • RoHS compliant
  • Annual need: 2000-7000 Pieces (additional rise expected due to use in other product families as well)

 

Key Success Criteria
  • 100Base-FX Ethernet compatible
  • Power supply 3.3V (typ.)
  • Electrical Interface (Signals) of Phy-Side of the Siemens-ASIC:
    • Receiver Data Input: LVPECL (3.3V PECL) differential
    • Transceiver Data Output: 3.3V / 12mA differential
    • Signal Detect Input: LVPECL (3.3V PECL) differential
    • Diagnose (SDA, SCL): 3.3V / 6mA CMOS
  • Endurance: long-life (e.g. 10 years at 24h, 365d p.y.)

 

Possible Approaches
  • Form Factor:
    • SF F (Possible Solution: 2 x SFF (op is) mounted on a pluggable module (PCB), grouted)
    • SF P (Solution ?: ATEX Ex II 2G (1G) Ex ib [op is Ga] IIC T4 Gb with Definition of

Ex-parameters: Voltage(i), Current(i), Power(i), Capacitance(i), Inductance(i))
