Notes:

1. Circuit ground is internally isolated from chassis ground.

2. TFAULT is an open collector/drain output, which should be pulled up with a 4.7k – 10k Ohms resistor on the host board if intended for use. Pull up voltage should be between 2.0V to Vcc + 0.3V.A high output indicates a transmitter fault caused by either the TX bias current or the TX output power exceeding the preset alarm thresholds. A low output indicates normal operation. In the low state, the output is pulled to <0.8V.

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

4. Should be pulled up with 4.7kΩ- 10kΩ host board to a voltage between 2.0V and 3.6V. MOD_ABS pulls line low to indicate module is plugged in.

5. Internally pulled down per SFF-8431 Rev 4.1.

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

FAQ

Listed below are answers to our most commonly asked questions. Don't see your question?Contact our customer service team. We would be glad to assist you.

What is an optical network terminal (ONT)? How does it differ from a regular modem?

An optical network unit (ONU) is an end device in a fiber optic network that converts optical signals transmitted via fiber optics into electrical signals (for use by routers, computers, and other devices), and vice versa.

What is the architecture of a fiber optic network (PON)?

Fiber optic networks typically use a passive optical network (PON) architecture, which is divided into three layers

What are the functions of the PON port and LAN port on an optical network terminal (ONT)?

PON port (fiber optic interface): Connects to the fiber optic cable entering the home and receives optical signals (usually SC/APC interface, blue square head).

Why does the optical network terminal need to register LOID/SN?

LOID (Logical Identifier) or SN (Serial Number) is the credential used by operators to bind user identities, and is used for OLT authentication of optical modems.

Optical modem dialing vs. router dialing: which is better?

Ordinary users: Optical modem dialing. Game/NAS users: Switch to bridge mode and dial up using a high-performance router.

How to determine whether the fiber optic signal is normal?

Check the optical modem indicator lights Log in to the optical modem management interface: Check the optical power (unit: dBm)
