DTC-01 OC-1 Single Mode Transceiver with Clock Recovery Features Full Compliance with OC-1 SONET Specifications Long Reach 1310 nm & 1550 nm and Intermediate Reach Eye Safe (Class I Laser Safety) Multi-sourced 2x9 package style Duplex SC or ST or FC connector - 40C to +85C Operating Temperature (option "A") Single +5 V supply & DATA & CLOCK PECL interface Wave Solder Process Compatible Description InGaAs PIN photodiode and a transimpedance amplifier IC with internal AGC for wide dynamic range. A PLL clock recovery IC is used to generate PECL data and clock. A Signal Detect status TTL output is also included. The DTC-01 fiber optic transceivers with clock recovery offer a simple, convenient way to interface ATM/SONET/SDH OC-1 PCBs to single mode fiber optic cables. Both Long Reach (1300 nm or 1550 nm) and Intermediate Reach versions are available using either DFB Lasers or Fabry Perot Lasers where appropriate. All modules satisfy Class I Laser Safety requirements in accordance with the US FDA/CDRH and international IEC-825 standards. The transceiver operates from a single +5V supply over an operating temperature range of 0C to +70C ("B" option) or - 40C to +85C ("A" option). The package is made of either conductive plastic with blue color (Duplex-SC version) or metal (FC and ST version) for excellent EMI shielding. The transmit and receive functions are contained in a two-row, 18-pin (2x9) package with a Duplex SC or ST or FC connector interface. The transmitter includes the laser driving circuitry as well as an Average Power Control (APC) loop to stabilize the transmitter average optical output power. A Transmitter Disable input, a Laser Back Facet Monitor and differential Laser Bias Monitor outputs and a Transmitter Alarm output are provided.

Interface circuit: The power supply line should be well-filtered. All 0.1 mF power supply bypass capacitors should be as close to the DTC transceiver module as possible. The two front GND posts should be grounded to Circuit Ground or Chassis Ground. Laser Safety: All transmitters are Class I Laser products per FDA/ CDRH and IEC-825 standards. They must be operated under specified operating conditions. Transmitter: When the DATA+ input is at logic HIGH and DATAinput is at logic LOW, the LD is ON; and vice versa. In single-ended applications, the unused input pin should be biased to VCC - 1.29 V. The transmitter is normally enabled (i.e. when the TX DISABLE input is not connected). When the TX DISABLE input voltage is higher than VCC - 2 V, the laser is turned off independent of the input data. A Transmitter End-of-Life Alarm (TALM) is also provided, which will switch to TTL level HIGH when the laser is reaching its End-of-Life. The transmitter incorporates an Average Power Control (APC) loop to stabilize the transmitter average optical output power against temperature variation. The APC loop always acts to keep the transmitter average optical output power at a constant value (assuming that the transmitter is enabled). Therefore, when the input data is all continuous "zeroes" or all continuous "ones", the transmitter optical output power is a constant level equal to the nominal average optical output power (not at the "OFF" level or at the "ON" level). Receiver: Both differential outputs (DATA+ and DATA-, CLOCK+ and CLOCK-) are PECL levels requiring termination (50 ohms to VCC - 2 volts or 510 ohms to GND is recommended). For optimum performance, both outputs should be terminated in the same manner, even if only one is used. The Signal Detect circuit monitors the level of the incoming optical signal and generates a TTL logic LOW signal when insufficient Optical Communication Products, Inc.

For full compliance with OC-1 Intermediate Reach standard, the DTC-01-xx-T-L3 modules are recommended. 2. For full compliance with OC-1 Long Reach 1310 nm standard, the DTC-01-xx-A-L0-LR1 and DTC-01-xx-B-L0-LR1 modules are recommended. The DTC-01-xx-A-L0-LR1 uses a DFB laser to satisfy the - 40C to +85C requirement for Center Wavelength. 3. For full compliance with OC-3/STM-1 Long Reach / L-1.2 standard, the DTC-01-xx-A-L0-LR2 and DTC-01-xx-B-L0-LR2 modules are recommended. Both modules use DFB lasers. However, the DTC-01-xx-A-L0-LR2 is specified only over - 25C to +70C. 4. The LR1 (- 40C to +85C) & LR2 options are available only with DFB lasers and L0 optical output power level.
