> Cabling the Channelized Line Cards
> This chapter provides information about the physical interfaces and instructions for installing the cables on the CLC2 (STM-1/OC-3).
> This chapter includes the following sections:

> • | Channelized Line Card Interfaces

> • | Cabling the Optical SFP Interface

> Channelized Line Card Interfaces
> The CLC2 card supports two types of Small Form-factor Pluggable (SFP) transceiver modules. The type of optical fiber interface on the line card is dictated by the SFP modules installed on the card. The SFP modules are hot-pluggable.
> SFP Modules Supported by the CLC2

> SFP Module Type | Card Identification | Interface Type | Cable Specifications
> Single-mode Optical Fiber | Channelized (STM-1/OC-3) SM IR-1 | Single-mode Fiber, LC duplex female connector | Fiber Types: Single-mode optical fiber Wavelength: 1310 nm Core Size: 9 micrometers Cladding Diameter: 125 micrometers Range: Intermediate/21 kilometers Attenuation: 0.25 dB/KM Min/Max Tx Power: -15 dBm/-8 dBm Rx Sensitivity: -28 dBm
> Multi-mode Optical Fiber | Channelized (STM-1/OC-3) Multi-Mode | Multi-mode Fiber, LC duplex female connector | Fiber Types: Multi-mode optical fiber Wavelength: 1310 nm Core Size: 62.5 micrometers Cladding Diameter: 125 micrometers Range: Short/2 kilometers Min/Max Tx Power: -19 dBm/-14 dBm Rx Sensitivity: -30 dBm

> Important: Because of the optical SFP interface, this product has been tested and found to comply with the limits for Class 1 laser devices for IEC825, EN60825, and 21CFR1040 specifications.
> The following figure shows the LC-connectors for the CLC2. Each SFP fiber interface provides both transmit (TX) and receive (RX) on the port
> CLC2 Fiber Interfaces
> Cabling the Optical SFP Interface
> To use the optical SFP interface on the a channelized line card, follow the instructions below.
> Warning: Only trained and qualified personnel should install, replace, or service this equipment. Invisible laser radiation may be emitted from the aperture of the port when no cable is connected. Avoid exposure to laser radiation and do not look into open apertures. Be sure to keep the cover on the interface when it is not in use. Laser Klasse 1 - nur speziell ausgebildetes Personal darf dieses Geraet warten. Nicht in den Laser schauen, um Augenverletzungen zu vermeiden. Nicht genutzte Buchsen mit der entsprechenden Kappe verschliessen.

> Step 1 | Remove the cover from the SFP interface.

> Step 2 | Insert the optical cable from a network device into the interface and ensure that it is securely in place.
