Description of BIDI SFP Transceiver


Bi-directional (BIDI) Small Form Factor Pluggable (SFP) transceiver module series is specifically designed for the high performance integrated duplex data link over a single optical fiber. These transceiver modules are compliant with the SFP Multisource Agreement (MSA).

With the hot pluggability, these modules offer an easy way to be installed into SFP MSA compliant ports at any time without the interruption of the host equipments operating online.BIDI SFP transceiver module series using a long wavelength DFB laser diode and enable data transmission up to 80km on a single-mode (9/125μm) optical fiber.


Structure feature of BIDI SFP Transceiver


The transmit and receive functions are contained in a SFP 20 pin package with a Duplex LC or SC connector interface. The transmitter incorporates a highly reliable 1310 nm or 1550 nm Laser (FP laser for narrow, Intermediate distance and DFB laser for long distance) and a driver circuit which converts data to light with APC function.

The output power can be disabled via the single TX_Disable pin. Logic LVTTL HIGH level disables the transmitter. The receiver incorporates an efficient InGaAs/InP PIN or APD photodiode receiver converting the light signal into an electrical current which is amplified and regenerated into data.


Application Fields of BIDI SFP Transceiver

  1. FTTH, FTTX, ATM/SONET, SDH, Ethernet, Fiber Channel
  2. High speed I/O bus extension, systems interconnects
  3. Data Communication for SAN and LAN
  4. Routers and switches, computer cluster cross-connect
  5. Industrial control links and media converters
