HMIM-1POS

Introduction

The 1-port SDH/SONET interface module (HMIM-1POS) supports interface rates up to 155.52 Mbps

(STM-1/OC-3).

The HMIM-1POS can use the protocols such as PPP, Frame Relay, and HDLC at the data link layer and IP

at the network layer. It allows direct transmission of packets over SONET/SDH.

It supports:

• The following types of SFP transceiver modules:

{ Multi-mode short-haul (1310 nm) SFP module

{ Single-mode medium-haul (1310 nm) SFP module

{ Single-mode long-haul (1310 nm) SFP module

{ Single-mode ultra-long haul (1550 nm) SFP module

• 155.52 Mbps fractional interface
