Module OYI-1L311xF

1250Mb/s SFP 1310nm 10km Optical Transceiver

Module OYI-1L311xF

OYI-1L311xF Small Form Factor Pluggable (SFP) transceivers are compatible with the Small Form Factor Pluggable Multi-Sourcing Agreement (MSA), The transceiver consists of five sections: the LD driver, the limiting amplifier, the digital diagnostic monitor, the FP laser and the PIN photo-detector, the module data link up to 10km in 9/125um single mode fiber.

The optical output can be disabled by a TTL logic high-level input of Tx Disable, and the system also 02 can disable the module via I2C. Tx Fault is provided to indicate that degradation of the laser. Loss of signal (LOS) output is provided to indicate the loss of an input optical signal of receiver or the link status with partner. The system can also get the LOS (or Link)/Disable/Fault information via I2C register access.

Notes:

1. Circuit ground is internally isolated from chassis ground.

2. Laser output disabled on TDIS >2.0V or open, enabled on TDIS <0.8V.

3. Should be pulled up with 4.7k-10k ohms on host board to a voltage between 2.0V and 3.6V.MOD_DEF

(0) pulls line low to indicate module is plugged in.

4. This is an optional input used to control the receiver bandwidth for compatibility with multiple data rates (most likely Fiber Channel 1x and 2x Rates).If implemented, the input will be internally pulled down with > 30kΩ resistor. The input states are:

1) Low (0 – 0.8V): Reduced Bandwidth 2) (>0.8, < 2.0V): Undefined

3) High (2.0 – 3.465V): Full Bandwidth

4) Open: Reduced Bandwidth

5. LOS is open collector output should be pulled up with 4.7k-10k ohms on host board to a voltage between 2.0V and 3.6V. Logic 0 indicates normal operation; logic 1 indicates loss of signal.

OYI-FOSC-D109H

The OYI-FOSC-D109H dome fiber optic splice closure is used in aerial, wall-mounting, and underground applications for the straight-through and branching splice of the fiber cable. Dome splicing closures are excellent protection of fiber optic joints from outdoor environments such as UV, water, and weather, with leak-proof sealing and IP68 protection. The closure has 9 entrance ports on the end (8 round ports and 1 oval port). The shell of the product is made from PP+ABS material. The shell and the base are sealed by pressing the silicone rubber with the allocated clamp. The entry ports are sealed by heat-shrinkable tubes. The closures can be opened again after being sealed and reused without changing the sealing material. The closure’s main construction includes the box, splicing, and it can be configured with adapters and optical splitters.
